Petite enfance et reconnaissance. Analyses à partir de l’œuvre d’Axel Honneth
Authors: Plaisance Eric
Published: November 2019

Le concept de reconnaissance est central dans l’œuvre du philosophe et sociologue allemand Axel Honneth. Ce n’est pas la reconnaissance au sens de la perception des choses ou des êtres, mais la reconnaissance morale et intersubjective des personnes, ce qui est, selon Honneth, au cœur de la constitution du lien social. Le premier niveau de cette reconnaissance concerne les relations affectives et, tout d’abord, les relations entre le jeune enfant, sa mère et son environnement proche. Dans ce texte, je propose de prolonger et de compléter les analyses de Honneth sur les processus de reconnaissance de la petite enfance en distinguant plusieurs aspects: la reconnaissance de l’âge spécifique de la petite enfance au cours de l’histoire; la reconnaissance moderne du jeune enfant et même du bébé comme une « personne » et leur place dans les institutions telles que crèches, jardins d’enfants, écoles maternelles (en prenant l’exemple de la France après la seconde guerre mondiale) ; les processus de reconnaissance mutuelle des jeunes enfants (par exemple à travers les activités de coopération dans les jeux); la reconnaissance interactive des jeunes enfants avec déficiences et difficultés diverses dans la problématique internationale actuelle de l’éducation inclusive.
Educação infantil em tempo integral: “mérito da necessidade” ou direito?
Authors: Araújo Vania Carvalho de , Auer Franceila , Neves Kalinca Costa Pinto
Published: November 2019

Tomando por referência o estudo exploratório realizado por Araújo (2015) sobre as práticas e as estratégias de atendimento da educação infantil em tempo integral em vinte instituições públicas do estado do Espírito Santo, este artigo problematiza a condição de vulnerabilidade e risco social das crianças e de suas famílias utilizada como critério predominante de matrícula, segundo relato de 90% dos gestores entrevistados. Chama a atenção para a necessária discussão sobre o modo como a demanda por vagas no tempo integral tem resultado em formas controversas de acesso ao manter as crianças mais próximas do “mérito da necessidade” do que das prerrogativas do direito. Conclui-se que, quando o “mérito da necessidade” se estabelece como critério predominante de acesso à educação infantil em tempo integral, uma visão reducionista do direito se interpõe, subvertendo-o como recurso equalizador de oportunidades e instância de mediação societária.
Educação infantil e suas infâncias: cultura, políticas e formação humana
Authors: Voltarelli Monique Aparecida , Araújo Vania Carvalho de
Published: November 2019

Encontrar novos espaços de interlocução sobre alguns temas que atravessam a Educação Infantil é o objetivo deste Dossiê. O esforço de reunir colaboradores que há anos vem dedicando grande parte de suas vidas a favor das diferentes infâncias e da educação infantil parece ser o maior mérito deste trabalho, pois é por meio de experiências profissionais tão diversas que é possível tornar público temas e problematizações que emergem do cotidiano da educação infantil e de suas infâncias. Os textos aqui apresentados reacendem lampejos de possibilidades em um contexto tão avesso ao enraizamento da cidadania nas práticas sociais, pois se trata de insistir na produção acadêmica como um bem público e por onde as prerrogativas do direito, da afirmação da diferença, da democracia se articulam com a produção de um conhecimento ético, responsável e emancipador.
Evaluation of Local Cryotherapy after Anterior Cruciate Ligament Reconstruction. Critical Review of the Literature
Authors: Bednarski Piotr , Kiwerski Jerzy
Published: November 2019

Background. At a time of innovative medical technologies development, it is paramount that medical services be evaluated with regard to their effectiveness. Research in physical medicine and rehabilitation, as well as the specialty itself, is relatively young; however, the number of publications in the field has recently been increasing. The main aim of this article is to evaluate the effectiveness of cryotherapy, including local cryostimulation, after anterior cruciate ligament reconstruction.
Material and methods. The present paper reviews scientific publications extracted from the Medline Embase, Cochra­ne Library, and PEDro databases according to a pre-designed search strategy. The review analysed publications where the authors indicated cryotherapy as an intervention in patients after ACL reconstruction and the study endpoints referred to analgesic or anti-oedema effects.
Results. As a result of selection, 16 publications were chosen for the analysis, including 1 meta-analysis, 2 systematic reviews and 13 RCTs. Only the results of randomised studies are presented. Endpoints referring to analgesic effects were present in all of the studies in the analysis, while endpoints referring to anti-oedema effects were present in five studies. Statistically significant results constituted 62% of the results for analgesic effects and 60% for anti-oedema effects.
Conclusions. 1. The currently limited evidence from randomised studies is not sufficient to draw final conclusions on the effectiveness of cryotherapy in patients after anterior cruciate ligament reconstruction. 2. It seems that cryotherapy can serve as an adjunct analgesic treatment in the early period after arthroscopic ACL reconstruction, while there is no notable improvement in patients after this procedure in reducing oedema.
Öffentliche Rundfunkorganisationen als Media Commons?
Authors: Schweizer Corinne
Published: November 2019

This volume uses the theory of the commons, which is often associated with Elinor Ostrom, to conduct a holistic analysis of public service broadcasting. The author argues that social participation, collaborative production and open access to content, as well as distance to markets and the state, are central to the legitimacy of this form of media organisation in the digital age. She discusses three opposing approaches to the theory of the commons and related ‘conceptual stumbling blocks’, and suggests 18 characteristics in order to analyse media organisations as ‘media commons’. By means of a document analysis, she examines 30 public service broadcasting organisations—including ‘the usual suspects’, like ARD, the BBC, ORF or SRG, but also lesser known organisations. She concludes that public service broadcasters feature some, but by no means all, of the characteristics of ‘media commons’ and that they operate with varying degrees of sustainability.

The Concept of "Fast Track Surgery" as an Influencer on the Dynamics of Components of Stress-Realizing and Stress-Limiting Systems in the Perioperative Period
Authors: Gerbali Oksana Yu. , Gumenyuk Lesya N. , Sarchuk Elena V. , Kerimov Enver Ya. , Karakursakov Nariman E.
Published: November 2019

The concept of "Fast Track Surgery" has been of increasing interest, which implies accelerated recovery and a decrease in the frequency of postoperative complications, namely, a decrease in the body's stress response to surgery. The study aimed to assess the effect of Fast Track Surgery on the degree of surgical treatment trauma based on the dynamics of the functional integration of hormonal components of the stress-realizing / stress-limiting systems in the perioperative period. The study was conducted in 3 groups of patients. Groups of patients are comparable in age, sex, diagnosis of an underlying disease, degree of operative-anaesthetic risk ASA, intraoperative parameters, which allowed to carry out an analytical evaluation of the results of the study as objectively and reliably as possible. In the postoperative period, the maximum increase in stress-realizing system parameters in all groups was registered in patients after 1 day after surgery, less significant after LSSI-F: the concentration of daily excretion of dopamine exceeded the preoperative values by 1.2 times, epinephrine 2.0 times, norepinephrine in 1.3 times. Along with the activation of the stress-realizing system, a dynamic increase in the activity of the stress-limiting system was noted: after LSSI-F, the level of GABA increased by 1.3 times, after TSSI, the GABA secretion increased 1.2-fold. Laparoscopic SSI in combination with "Fast Track Surgery" contributed to a decrease in the intensity of the patient's stress response to the operating injury, which, in turn, significantly increased the effectiveness of simultaneous treatment and the quality of life of patients.
Outstretched Index Finger - A Pointer is Peculiar Behaviour Characteristic of Angelman Syndrome in Adults – A Case Series Study
Authors: Martin Peter
Published: November 2019

Objective: To describe a behavioural feature, the outstretched pointing (and shaking) index finger, as a clue to the clinical diagnosis of Angelman syndrome (AS) in adults.
Methods: A case series, consisting of 43 adult individuals with the clinical diagnosis of AS, approved by genetic testing is presented. In 16/43 patients the clinical diagnosis was made by the author, mostly due to behavioural signs, including the pointing gesture, which he had increasingly noticed as a behavioural key feature in his adult patients with AS.
Conclusion: Pointing with the outstretched index finger is a communicative gesture frequently seen in adult persons with AS. Its absence is most likely due to more limited motor and/or intellectual functions, in phenotypes caused by deletions of 15q11-13 respectively. It can be seen as a clinical sign that significantly contributes to the diagnosis in adulthood.

Investigating the Prevalence of Latent Tuberculosis among Healthcare Workers of Major Hospitals of Ahvaz, Iran
Authors: Bavarsad Amir Hooshang , Idani Esmaiel , Shoushtari Maryam Haddadzadeh
Published: November 2019

Background and Objective: Healthcare and laboratory workers in hospitals have a higher exposure to hospital-acquired infections (HAIs) than the general populations. Tuberculosis (TB) infection is a common HAI that is communicated from the patients with TB admitted or hospitalized in the healthcare centres. This study aims to determinate the incidence and prevalence of latent TB infection among healthcare workers in the major Hospitals in Ahvaz, Khuzestan province, Iran.
Methods: This is a case-control study conducted on healthcare workers diagnosed with TB between January 2010 to December 2017. The study population consisted of healthcare workers of the three major hospitals of Ahvaz, Khuzestan including Imam Khomeini Hospital, Golestan Hospital and Shafa Hospital. All subjects underwent Mantoux tuberculin skin test (TST) and after 48 to 72 hours the reaction was measured as the length of induration. The induration equal to or greater than 10 mm was considered as positive TB. Moreover, the subjects and controls were asked to complete a self-administered questionnaire on potential risk factors for TB.
Results: Among 513 subjects, male and female subjects were respectively 186 and 327. Of all subjects, 67 subjects (male: 42; female: 25) showed positive TST (10 mm ≤ induration) and 275 subjects showed 5 mm >induration. There was a significant relationship between TST result and the workplace of the subjects. Gender showed no significant relationship with the TST result.
Conclusion: All healthcare workers who are in direct contact with TB patients must undergo regular TB screening test and the workers should be trained for self-conducting TST.
Does Late-Onset Huntington Disease Represent a Distinct Symptomatic Picture? Evidence for a Selective Deficit in Executive Function and Emotion Recognition, in the Absence of Behavioral and Psychiatric Disorders
Authors: Cossu Maria Cristina , Conti Matilde , Palma Veronica Di , Boccia Maddalena , Sabatini Umberto , Guariglia Cecilia
Published: November 2019

Huntington Disease (HD) is an autosomal-dominant, neurodegenerative disorder, including motor, cognitive, emotional and behavioral symptoms. Motor symptoms used to set the clinical onset, typically emerge in the middle age. Here, we describe the case of a patient, who received a genetic diagnosis at 75 years and developed motor symptoms at 80. The Patient shows severe motor symptoms in the absence of personality changes or psychiatric disorders typically observed in HD. For what attain neuropsychological profile, it results unaltered apart from a specific deficit in emotion recognition and general slowness on executive functioning tasks, reflecting a specific trade-off between accuracy and rate of performances, that is a selective impairment in fine-tuning of resources. Both of these deficits in the Patient could be ascribable to the frontostriatal atrophy, evidenced by Computed Tomography. While deficit in emotion recognition is a well-known symptom in HD, a deficit in fine-tuning of resources regards a specific aspect of executive function. The ability of fine-tuning resources is the latest step in the development of executive functions, and it could be also the first level to be impaired in HD. We proposed that deficit in fine-tuning of resources could be the core of the neuropsychological deficit in late-onset HD.

ABSTRACT:
The purpose of this work is to optimize the fracture resistance of the EPS parts used in the packaging of electronic products by using iterative DE-Experiment Design, as a more effective methodology to improve the performance of the productive processes than when It is done in isolation. The iterative DE was applied in a process of molding polyethylene pieces (EPS) in three stages: selection, modeling and optimization. In the selection stage the most important factors of the process were determined; in the modeling stage he determined how the important factors affect the process and in the optimization stage the optimum levels were established. Keeping the process operating within the ranges obtained brought with it a better control of the process with the following benefits: Reduction of the cycle time in 26.6. %; Reduction of the extra monthly time in 77%, and Reduction of charges for returns of rejected products in 85%.

Keywords: Process Improvement Strategy, Design of Iterative Experiments, Optimization of packaging resistance.

The Paradoxes of Network Neutralities
Authors: Newman Russell A.
Published: November 2019

An argument that the movement for network neutrality was of a piece with its neoliberal environment, solidifying the continued existence of a commercially driven internet.

Media reform activists rejoiced in 2015 when the FCC codified network neutrality, approving a set of Open Internet rules that prohibitedproviders from favoring some content and applications over others—only to have their hopes dashed two years later when the agency reversed itself. In this book, Russell Newman offers a unique perspective on these events, arguing that the movement for network neutrality was of a piece with its neoliberal environment rather than counter to it; perversely, it served to solidify the continued existence of a commercially dominant internet and even emergent modes of surveillance and platform capitalism. Going beyond the usual policy narrative of open versus closed networks, or public interest versus corporate power, Newman uses network neutrality as a lens through which to examine the ways that neoliberalism renews and reconstitutes itself, the limits of particular forms of activism, and the shaping of future regulatory processes and policies.

Newman explores the debate's roots in the 1990s movement for open access, the transition to network neutrality battles in the 2000s, and the terms in which these battles were fought. By 2017, the debate had become unmoored from its own origins, and an emerging struggle against “neoliberal sincerity” points to a need to rethink activism surrounding media policy reform itself.
The Artist in the Machine
Authors: Miller Arthur I.
Published: November 2019

An authority on creativity introduces us to AI-powered computers that are creating art, literature, and music that may well surpass the creations of humans.

Today's computers are composing music that sounds “more Bach than Bach,” turning photographs into paintings in the style of Van Gogh's Starry Night, and even writing screenplays. But are computers truly creative—or are they merely tools to be used by musicians, artists, and writers? In this book, Arthur I. Miller takes us on a tour of creativity in the age of machines. 

Miller, an authority on creativity, identifies the key factors essential to the creative process, from “the need for introspection” to “the ability to discover the key problem.” He talks to people on the cutting edge of artificial intelligence, encountering computers that mimic the brain and machines that have defeated champions in chess, Jeopardy!, and Go. In the central part of the book, Miller explores the riches of computer-created art, introducing us to artists and computer scientists who have, among much else, unleashed an artificial neural network to create a nightmarish, multi-eyed dog-cat; taught AI to imagine; developed a robot that paints; created algorithms for poetry; and produced the world's first computer-composed musical, Beyond the Fence, staged by Android Lloyd Webber and friends.

But, Miller writes, in order to be truly creative, machines will need to step into the world. He probes the nature of consciousness and speaks to researchers trying to develop emotions and consciousness in computers. Miller argues that computers can already be as creative as humans—and someday will surpass us. But this is not a dystopian account; Miller celebrates the creative possibilities of artificial intelligence in art, music, and literature.
From the Inside Out
Authors: Harrison Jill Lindsey
Published: November 2019

An examination of why government agencies allow environmental injustices to persist.

Many state and federal environmental agencies have put in place programs, policies, and practices to redress environmental injustices, and yet these efforts fall short of meeting the principles that environmental justice activists have fought for. In From the Inside Out, Jill Lindsey Harrison offers an account of the bureaucratic culture that hinders regulatory agencies' attempts to reduce environmental injustices.

It is now widely accepted that America's poorest communities, communities of color, and Native American communities suffer disproportionate harm from environmental hazards, with higher exposure to pollution and higher incidence of lead poisoning, cancer, asthma, and other diseases linked to environmental ills. And yet, Harrison reports, some regulatory staff view these problems as beyond their agencies' area of concern, requiring too many resources, or see neutrality as demanding “color-blind” administration. Drawing on more than 160 interviews (with interviewees including 89 current or former agency staff members and more than 50 environmental justice activists and others who interact with regulatory agencies) and more than 50 hours of participant observation of agency meetings (both open- and closed-door), Harrison offers a unique account of how bureaucrats resist, undermine, and disparage environmental justice reform—and how environmental justice reformers within the agencies fight back by trying to change regulatory practice and culture from the inside out. Harrison argues that equity, not just aggregated overall improvement, should be a metric for evaluating environmental regulation.
Material and Mind
Authors: Bardt Christopher
Published: November 2019

An in-depth exploration of the interaction between mind and material world, mediated by language, image, and making—in design, the arts, culture, and science.

In Material and Mind, Christopher Bardt delves deeply into the interaction of mind and material world, mediated by language, image, and the process of making. He examines thought not as something “pure” and autonomous but as emerging from working with material, and he identifies this as the source of imagination and creative insight. This takes place as much in such disciplines as cognitive science, anthropology, and poetry as it does in the more obvious painting, sculpture, and design. In some fields, the medium of work is, in fact, the very medium of thinking—as fabric is for the tailor.

Drawing on the philosophical notions of the “extended mind” and the “enactive mind,” and looking beyond the world of material-based arts, Bardt investigates the realms in which material and mind interweave through metaphor, representation, projection, analogues, tools, and models. He considers words and their material origins and discusses the paradox of representation. He draws on the design process, scientific discovery, and cultural practice, among others things, to understand the dynamics of human thinking, to illuminate some of the ways we work with materials and use tools, and to demonstrate how our world continues to shape us as we shape it. Finally, he considers the seamless “immaterial” flow of imagery, text, and data and considers the place of material engagement in a digital storm.

Published: November 2019

This was the first study in Yemen, and Gulf of Aden aims to investigate the marine organisms in ballast water and sediments, and gives baseline information defines the zooplankton, phytoplankton and invertebrates, associated fuel tankers. Samples from Ballast water were taken from three ships that arrived at Mukalla Port, the Hadhramout coast from ports of Hamriyah port, U.A.E; ports of Taheri, Iran; and Bosaso Somalia (MT: Gulf Petroleum III, MT: Prime Royal, and M T: Breu) respectively. The marine organisms in samples were presented by three taxonomic groups, phytoplankton, zooplankton and benthos. Fifty-eight taxa were identified within this study; which consisted of 17 phytoplankton, 18 zooplanktons and 23 Benthos. The highest density of phytoplankton was 21 Ind/L, with the occurrence of 17 species found in ballast water, while 22 Ind/50cc of 2 species in sediment samples of the tanker Beru, and fewer densities were in Gulf Petroleum and Prim Royal. The most common phytoplankton observed were Coscinodiscus granii, Coscinodiscus jonesianus and Thalassiosira eccentric. The low Zooplankton density was 13 Ind/L with an occurrence of 18 species found in Prim Royal tanker. Copepods were the most dominant zooplankton among the three tankers. Paracalanus parvus had the highest value of dominance followed by Calanopia parathompsoni, Acrocalanus gracilis and Paracalanus denudatus had the lowest occurrence over three tankers. Seven taxa of Dinoflagellates were identified; two of them Ceratium fusus and polykrikos sp. are known to be harmful species.

Development of commercial formulation of botanicals used to enhance the probability of managing such pathogenic bacteria. Further investigations are necessary for developing commercial formulations based on fields, animal trails, and toxicological experiments. This research may be footprint towards managing the newer antimicrobial entities against the fish pathogen.
Unexpected Covariances between Shell Growth Parameters are Controlling the Range of Interspecific Variations of Shell shape in the Deep-Sea Clams Genus Calyptogena (Bivalvia: Veneroida)
Authors: Béguinot Jean
Published: November 2019

In Bivalves, shell shape descriptors (in particular, elongation E, dissymmetry D, ventral convexity K) are considered functionally-relevant parameters, each of them likely being exposed to specific selective pressures, according to environmental conditions. Indeed, previous investigations, have repeatedly confirmed that different types of constraints do apply to the respective ranges of interspecific variations of E, D, K: in particular, a trend for a substantially extended range of interspecific variation of shell-elongation E (likely attributed to niche differentiation) and, on the contrary, a trend for a severely restricted range of interspecific variation of ventral-convexity K (closely centered at an optimum for mechanical resistance of valves). In turn, due to rigid geometrical relationships linking shell-shape to shell-growth, this pattern of constraints on shell-shape variations implies, mathematically, the occurrence of specifically associated covariances between shell-growth parameters, the occurrence of which were, indeed, repeatedly observed within all groups of shallow-waters clams examined so far. Yet, the fairly different environmental conditions prevailing at bathyal / abyssal depths invite addressing comparatively some typically deep-sea clams; hereafter the genus Calyptogena. Contrary to expectation, the same types of covariances between shell-growth parameters are reported in deep-sea Calyptogena as those reported in shallow-waters clams, thus suggesting less dissimilar patterns of constraints than expected between shallow waters and deep-sea conditions.

Published: November 2019

This experiment was designed with three experimental treatments namely T1 (natural feed), T2 (feeding with 10% body weight) and T3 (feeding with 5% body weight) for ten weeks. In the content of 33.8% of crude protein (CP), 11.2% of crude fiber (CF), 6% of fat and 10.2% of ash content feed were used as an experimental diet in this experiment. The stocking densities were 280 fish decimal-1 in three treatments where the mean initial weight of fry was 20 ± 0.2 g in all treatments combined and at the end of the experiment the mean final weight was found as 58.9 ± 2.86 g, 134.4 ± 3.62 g and 142.5 ± 4.23 g for T1, T2, and T3 respectively. Mean initial length was 10.2 ± 0.01 cm in three treatments and final length was found as 14.58 ± 1.60 cm, 18.74 ± 1.23 cm and 20.16 ± 2.08 cm in T1, T2 and T3 respectively. The mean weight gains 38.9 ± 1.53 g, 114.4 ± 3.05 g and 122.5 ± 1.5 g, mean length gain 4.38 ± 0.24 cm, 8.54 ± 0.65 cm and 9.96 ± 0.59 cm, mean SGR 1.76%, 3.5% and 3.82% were recorded in T1, T2 and T3, respectively. The highest weight gain, length gain and SGR were found in T3 and the lowest was found in T1. The survival rate was 82%, 88% and 94% in T1, T2 and T3, respectively. FCR values were found as 3.49 ± 0.5 and 2.51 ± 0.4 in T2 and T3. The result demonstrated that feeding with 5% body weight had a better effect on the growth and survival rate of monosex (male) O. niloticus.

Published: November 2019

Seaweeds or marine macro-algae form the base for the marine ecosystems and considered as direct or indirect source of food for people across the world. Today, algae have made their way to almost all the areas of human life like food, feed, fuel, medicines etc. Marine algae provide exceptional diverse storage of bioactive compounds such as antimicrobial elements. 5 different varieties of seaweeds were collected from Salalah and they were: Ulva fasciata, Asparagopsis taxiform, Rhizoids of Jolyna laminarioide, Jolyna laminarioides and Laminaria brasiliensis. The biochemical composition of these seaweeds were determined by using several analytical techniques such as gas chromatography coupled with mass spectrometry and spectrophotometric methods. The phenolic content, antioxidant of TPC, DPPH (2,2-Diphenyl-1-Picrylhydrazyl) and FRAP analysis were measured. The results have shown a higher antioxidant activity in Brown (Rhizoids of Jolyna laminarioides) comparing with the other varieties. The antimicrobial activity of Ulva fasciataon on E. coli (G-) and Rhizoids of Jolyna laminarioides) on S. aureus (G+) was higher comparing with the control sample and the difference was significant (p < 0.05). In conclusion, this study points out the possibility of seaweeds to be used in making different products that can be employed in biotechnological, nutraceutical and pharmaceutical applications even though more investigations are required for separating, purifying and characterizing the varieties of seaweeds in Oman.

Published: November 2019

This study was carried out to evaluate the length-weight relationship, growth pattern and condition factor of the Silver catfish Chrysichthys nigrodigitatus from the Lower River Benue Makurdi, Nigeria. A total of 200 freshly caught specimens of C. nigrodigitatus were collected between July 2013 and September 2013 from the catches of the artisanal fisheries at landing points in Wadata Market, Makurdi. Results obtained showed that the “b” value for the males was 1.6067 while that of the females was 1.6791 and combined sexes 1.7371, indicating a negative allometric growth for this species. Correlation coefficient (r) obtained for males (0.9651), 0.9517 (females) and 0.9329 (pooled sexes) showed a positive significant relationship between length and weight of C. nigrodigitatus.

Production of white leg shrimp (Penaeus vannamei) is a very important economic activity in the overall farming system in China. In spite of the present successes witnessed by white leg shrimp farming, there are many challenges (disease, overfeeding, effluent discharge, lack of technical knowledge, low educational level, inexperienced managers, the high cost of production among others) continuing to set back the growth of this sector in China. The study was conducted in Jiangsu province because is one of the leading producing provinces of White-leg shrimp (Penaeus vannamei) in China. The research examines the technical efficiency level of white leg shrimp production in Jiangsu Province, China. Three seasonal crops data in 2016 crop year were collected from 52 white leg shrimp farmers in the study area. All data were coded in Excel 2007 spreadsheet package and analysed with SPSS version 20 and DEAP version 2.1 software at 95% confidence level. Descriptive statistical, regression and Data Envelopment Analyses (DEA) were used to analyse the data. Results revealed an average technical efficiency score of 83.1%, under a constant return to scale. Majority of the farmers (62%) were technically inefficient in utilising input resources with technical efficiency score less than 1. Twenty farmers were technically efficient with technical efficiency (TE) score equal to 1. Feed, fingerlings and chemical showed significant negative influence on technical efficiency at 5% level of significance while labor, fixed cost and age exhibited strong negative impact at 1% level of significance.

Authors: Felix Eze , Oscar Eyo Victor
Published: November 2019

The objective of this study was to evaluate the floating and stability of fish feed pellets formulated with different concentration of Baobab (Adansonia digitata) leaf meal (BLM). Five isonitrogenous fish feed (35% CP) with varying inclusion levels of Baobab leaf meal (0% BLM, 4% BLM, 8% BLM, 12% BLM and 16% BLM designated as D1, D2, D3, D4 and D5 respectively was used. Ten (10) pellets of each experimental feed were placed in plastic beaker (55 x 25 x 30 cm) for 50 minutes. Feed pellet floatability and stability were recorded every five minutes. Results showed that feed pellet floatability increased significantly (P<0.05) with increase in BLM concentration. Highest feed pellet floatability (41.66 ± 2.88 minutes) was recorded in D5 (16% BLM) and least (0.00 ± 0.00 minutes) in D1 (0% BLM) which sank down immediately. Similarly, feed pellet stability increased significantly (P<0.05) with increase in BLM concentration. Highest pellet stability (42.66 ± 1.17 minutes) was recorded for D5 (16% BLM) and least (18.54 ± 2.10 minutes) in D1 (0% BLM). Based on these findings, it is concluded that 16% BLM inclusion level in fish feed has led to a high pellet floatability and stability. Therefore, Baobab leaf meal (BLM) which is relatively cheap, toxic free, easy to process and available specifically in Northern part of Nigeria is recommended for floating feed formulation.

Published: November 2019

The current study was performed to monitor in situ condition and spatio-temporal modelling of the present status of water quality parameters of different spawning grounds and sanctuaries of Hilsha. The study was conducted in nine sites in lower Padma River (Maowa) to lower Meghna River (Bhola, Patuakhali) from 1 August 2015 to 31 January 2016. This study demonstrates surface water temperature, salinity, conductivity and transparency were ranged from 19.00-33.00°C, 0.10-2.90 ppt, 125.60-4720.00 µS/cm and 6.60-74.00 cm respectively. The values of pH, DO, free CO2, total alkalinity, total hardness and free NH3 were varied from 6.00-9.50, 4.50-11.60 mg/L, 3.46-24.00 mg/L, 33.00-172.50 mg/L, 34.20-1291.00 mg/L and 0.20-1.40 mg/L respectively. Moreover, water quality model reveals that the present status of some water quality parameters (free CO2, free NH3, transparency) deviated from optimum condition suitable for the normal physiological process and spawning of Hilsha.

Aims: Improve production of Clarias gariepinus fry through the use of local materials.

Place and Duration of the Study: From 1st April to 09th May 2016 at the Akak Essatolo Fish Farm in Ebolowa, South Region Cameroon.

Study Design: 10 broodstock of C. gariepinus, were used for the artificial reproduction. Pituitary extract and Ovaprim hormones were used to induce oocytes maturation on females. Eggs were obtained by the abdominal pressure of the female. Wicks (or Local raffia fibbers (Raphia regalis)) and mesh frame were used as incubators of fertilised eggs. 12 experimental batches each consisting of 50 g of fertilised eggs were spread in triplicates on both types of incubators previously arranged in closed-circuit tanks.

Methodology: Fertilized eggs were enumerated by direct observation. At the end of the hatching (D0) and of vitelline resorption (D3), larvae of each experimental lot were counted.

Results: Similar (P = .05) absolute and relative fecundities used were recorded in all treatments. Female eggs induced with pituitary extracts and incubated on raffia fibbers recorded lower (P ˂.05) fertilisation and hatching rates. All other treatments were comparable (P = .05) for these parameters. Deformed larvae rates were comparable (P = .05) for all treatments. Survival rates at the end of yolk sac resorption (J3) were higher (> 70%) in all treatment. However, treatment with Ovaprim and wick showed a survival rate (71.1%) significantly (P ˂ .05) lower than the other treatments (> 80); which have otherwise remained comparable (P = .05).

Conclusion: The superiority of ovaprim at the beginning of reproduction is offset by the poor survival rate, which is better with the pituitary gland. It is therefore concluded that the use of the synthetic hormone is not economical for optimal production of C. gariepinus fry. In the same way a mastery of the use of the raffia fibres will improve the cost-effectiveness and consequently will decrease the production costs.

Published: November 2019

The effect of different inclusion levels of wonderful kola (Buchholzia coriacea) seed meal (BSM) on growth performance and survival rate of Oreochromis niloticus fry was investigated. Five days old mixed sex of O. niloticus (0.1– 0.2 g weight and 0.45 mm length) were subjected to powdered B. coriacea seeds meal (BSM) at 0, 2, 4, 6, 8 and 10 g/kg twice daily for 1 month from April-May, 2015. It was conducted in an indoor experimental plastic basin of capacity 50 cm in diameter and 30 cm deep. 60 fry per duplicates with a total of 720 fry, six isonitrogeneous treatments and 2 duplicates per each treatment. A complete randomized design and 30% Crude Protein were used. The highest mean length, mean weight, specific growth rate and weight gain observed are 0.488 mm, 4.68 g, 0.85 and 4.65 g respectively. The highest of survival rate (100%) was recorded in fish fed with 6 g/ kg BSM. Treatment 1 having 0% BSM (control) had the lowest weight gain. In conclusion, the addition of 4 g/ kg of BSM in a fish diet, has no negative effect on the growth performance and survival of O. niloticus.

Although sea cucumber Holothuria scabra has always been part of the traditional exploitation of the benthos of Mahout Bay in the Arabian Sea, the foreign demand for the product and its high price have put increased pressure on the resource leading rapidly to overfishing. Aquaculture of this species has developed as a response to the overfishing problem but has not been yet studied in Oman. As a first step to evaluate its potential for aquaculture in Oman it was thus necessary to conduct hatchery trials. Four hatchery trials were conducted to evaluate the quality of the local broodstock, the response and efficiency of in-vitro maturation and fertilization and the success of larval development and rearing. Collected animals of 200-600 g were transported by road for 5 hours with zero evisceration to the Hatchery station. In-vitro maturation and fertilization success of more than 90% were achieved using the maturation inducing fractions (MIF) method leading to the development of mature eggs and normal embryos larvae. Auricularia larval stages were completed within 15 days and fed normally on microalgae Phaeodactylum tricornutum, Chaetoceros sp. and Nanochloropsis sp. Average settlement rate and size for pentactula juveniles were closely to 9% and 0.5 mm, respectively, nearly one month post-fertilization (PF). However, a high mortality of 70% was observed during early larval development caused by ciliated protozoans and copepods attack. The culture of H. scabra population in Oman is thus promising but further research is needed to ensure higher survival rates, particularly in the early larval stages where adequate water filtration and sterilization is essential.

Global technological advancement has resulted in the gradual replacement of traditional bulk size compounds with nano-sized ones with diverse useful characteristics. This study is focused on the toxicological assessment of three nano-metallic oxides (SiO2, Al2O3 and CuO) in comparison with their equivalent bulk sizes using African Catfish (Clarias gariepinus). The study involved sub-lethal exposures to binary mixtures of selected ratios (1:1; 2:1 and 1:2) of the respective metallic bulk and nano oxides as well as their triple mixture (1:1:1) for 28 days. The catfishes after 28 days were subsequently subjected to haematological tests (Haemoglobin, Packed Cell Volume, Red blood cells, Platelets, Neutrophils, Lymphocytes, Mean cellular volume, Mean Cell haemoglobin, and Mean Cell haemoglobin Concentration). The results of the haematological assessment indicated that most of the nano-sized oxides showed no significant difference (P>0.05) compared to control whereas the bulk sizes either showed no difference or decrease in the count compared to control. In most of the binary mixtures, catfishes exposed to bulk sizes had lower levels of the haematological parameters but there was no overall trend. The introduction of nanoscale metallic oxides into production activities should be with caution since they may have a similar mode of toxicity to the existing bulk sizes.
