Effect of land use and survey design on trip underreporting in Montreal and Toronto’s regional surveys
Authors: Harding Chris , Nasterska Monika , Dianat Leila , Miller Eric J
Published: November 2023

This paper contributes to the literature on travel survey methods by quantifying the relationship between land use, data collection protocol and trip under-reporting in regional travel surveys. While under-reporting more broadly is a recognized problem, the significant increase in underreporting in denser, more urban-type environments identified here has never before been demonstrated or measured. Consequences of this land use-related bias for transportation planning and modelling are explored. The work is carried out by comparing the results of two very similar household travel surveys conducted in 2011 and 2013, in Toronto and Montreal respectively. Using data on over 350,000 persons, a binary logit model for discretionary trip making is estimated and the effects of land use and data collection protocol on under-reporting are isolated. This is done by controlling for mobility tool access, household type and other key determinants of travel demand. Counterintuitive effects for urban type environments found indicate the under-reporting effect is equivalent to a reduction in the pre-existing odds of reporting discretionary trip making in more urban environments of 19 to 29%. When combined with Toronto’s data collection protocol effect, the range increases to 39 to 55%. Results should be of use to transportation planning authorities wishing to make better use of the data collected in large surveys. Recognizing some of the flaws and biases in what is reported, these authorities can complement existing sources of data or modify their approaches to demandbased infrastructure provision to better account for the large number of, largely pedestrian, unreported trips.
Persistent and Transient Efficiency of International Airlines
Authors: Heshmati Almas , Kumbhakar Subal C. , Kim Jungsuk
Published: November 2023

This paper examines the efficiency of international airlines for the period 1998-2012 using some competing stochastic frontier (SF) panel data models. It estimates a cost function for multi-output airline services, separating passenger and goods transportation at the national and international levels. Our preferred SF model distinguishes airlines heterogeneity from time-invariant persistent inefficiency, and transient (time-varying) inefficiency from random the noise component. This four component SF model is compared with two other competing SF models in which one of the four components is missing. All the models are estimated using the maximum likelihood method. The models give predicted values of persistent, transient and overall efficiency for each airline and time period. The mean and dispersion of cost efficiency amongst airlines differ by model specifications and according to their geographical area of operations. The performance difference may be a consequence of different market structures and deregulation processes and of specific competitive conditions such as resource availability and strategic alliances with competitors. The results confirm that, in general, none of the airlines is able to achieve full cost efficiency. We find that carriers based in the Asia region are more efficient than those operating in the European and North American regions. The bigger airlines are unable to take full advantage of economies of scale and are not more efficient than their smaller cousins.

Logistics decisions in descriptive freight transportation models: A review
Authors: Tavasszy Lorant , de Bok Michiel , Alimoradi Zahra , Rezaei Jafar
Published: November 2023

The objective of this paper is to provide an inventory of approaches to descriptively (as opposed to normatively) model logistics decisions within the context of freight transport modelling. Rather than taking transport modelling frameworks as a starting point, as has been the case in the literature so far, we depart from a framework of logistics decisions. The framework is developed by combining elements of over a dozen existing frameworks from the supply chain management literature. Based on this comprehensive framework, we review freight modelling approaches from the literature. We find that freight modelling can be extended by taking into account previously uncovered areas of logistics decisions, such as those related to marketing or logistics systems forecasting and planning, as well as in areas that are well known from an optimization perspective but not from a descriptive perspective, such as routing and scheduling decisions. We conclude with a systematic listing of such areas, which can be used by researchers and transport modelling practitioners to develop further those transport models that take agent decision making as a starting point.
Importance of freight mode choice criteria: An MCDA approach
Authors: Tavasszy Lorant , van de Kaa Geerten , Liu Wan
Published: November 2023

Road transportation has been the dominant mode for inland freight transportation for decades. Rail and waterways transportation are less frequently used alternatives, but in general more attractive from an environmental perspective. Even though many policies promoting the use of intermodal transportation have been proposed, they have had little impact to trigger shippers to shift mode from road transportation to rail or inland waterways transportation. One main reason might be that the requirements of shippers towards transportation modes are still not well understood. Hence this research investigates freight transportation mode choice with a new approach, multi-criteria decision analysis, as well as from the perspectives of different types of industries and experts. Reviewing the literature, the requirements for transportation modes are abstracted into a set of criteria, including transportation cost, door-to-door travel time, on-time reliability, flexibility, frequency, and reduction of CO2 emissions. As the importance of these factors might be different for different industries, we consider four segments: the manufacturing industry, the agriculture industry, the perishable food industry, and the chemical industry. Data from practitioners, industry experts, and academics are collected via online questionnaires and analyzed using the ‘best worst method’ (BWM) to identify weights for the mentioned criteria. The results indicate that transportation cost is viewed as the most important, closely followed by on-time reliability, while reduction of CO2 emission is viewed as the least important. Several comparison studies are conducted to see any difference in the importance of these factors with respect to different industries or respondent groups.
Selection of biogas, solar, and wind power plants’ locations: An MCDA approach
Authors: Kheybari Siamak , Mahdi Rezaie Fariba
Published: November 2023

This study discusses a multi-criteria approach to locating biogas, solar and wind power plants that significantly addresses the challenge of global warming caused by power generation. Because the utility of locations to build renewable energy power plants depends on economic, social and environmental dimensions, after reviewing literature, the sustainable frameworks of criteria affecting the location of biogas, solar and wind power plants were examined in this paper. The offered frameworks are applied to determining the site of biogas, solar, and wind power plants in Iran. The provinces of Iran are assessed as alternatives in this paper. To compute the weight of criteria in the offered framework, data from a sample of experts in Iran are used via an online survey form designed based on the best-worst method (BWM). Using the results of the BWM and the performance data, the overall score are calculated for the various provinces of Iran. The results of this study indicate that energy saving, effect on resources and natural reserves and wind flow, respectively, are the most effective factors for determining the place of biogas, solar and wind power plants, and South Khorasan, Khuzestan, and Khuzestan show the best result for establishing biogas, solar, and wind power plants in Iran respectively.
On the value of the Digital Internet / Physical Internet analogy
Authors: van Luik Sharon , Fiebig Tobias , Fahim Patrick , de Waard Pieter , Tavasszy Lorant
Published: November 2023

Classical logistic networks have long since struggled with the increasing demand for flexibility and responsiveness, driven by the emancipation of consumers and the globalization of our world. Hence, since 2010, researchers in the logistics domain propose the ‘Physical Internet’ (PI) as guiding vision for innovations in logistic networks. The PI model adopts concepts and ideas from the ‘Digital Internet’ (DI) world and applies these to the movement and storage of physical products. While researchers have been working with this analogy for the past decade, a debate has emerged about the value of the DI/PI analogy and its usefulness for guiding the design of the PI. Specifically, prior work has not focused on ascertaining the accuracy of the analogy, i.e., how well logistics researchers have adopted concepts from the Digital Internet, and how this may influence the value of the analogy in the current discourse. The aim of this paper is to help fill this gap, using a qualitative research approach. We use 15 semi-structured expert interviews, to determine how well the DI is understood among the experts working on the DI/PI analogy. We propose the Analogy Functionality Model to interpret the results and assess the current strength of the analogy. We find that the strength of the DI/PI analogy varies across functions. Its application value lies particularly in the persuasion of stakeholders, the accessible explanation of key concepts, and the gathering of inspiration for further design directions. This underlines the importance of the analogy for the PI innovation community. Researchers and logistics practitioners should, however, refrain from using the analogy as a blueprint for the design of PI systems. For implementation purposes, we recommend that researchers move to conceptually emancipate the PI from the DI.

Il corpo violato, il corpo liberato: autodistruzione e catarsi in La Muñeca menor di Rosario Ferré
Authors: Giacchino Giovanna
Published: November 2023

La teoria sull’auto-riconoscimento dell’universo femminile elaborata da Hélène Cixous nel saggio La Risa de la Medusa (1975) unitamente ai meccanismi di alienazione postcoloniale analizzati da Franz Fanon ne I Dannati della terra (1961) hanno, a mio avviso, ispirato Rosario Ferré nell’elaborazione delle strategie letterarie adottate nel racconto La Muñeca menor. L’intento di Ferré è quello di demistificare e rovesciare il sistema patriarcale vigente attraverso una scrittura autobiografica, sovversiva e iraconda. La ribellione che caratterizza le eroine femminili de La Muñeca menor si compie attraverso la catarsi e la consunzione dei loro corpi. La loro autodistruzione liberatoria apre la strada a una vera e propria decolonizzazione dell’anima. La scrittrice portoricana si prefigge di mettere in luce attraverso il racconto le ripercussioni emotive generate dai processi coloniali. Ferré teorizza inoltre una nuova cosmogonia in cui le donne portoricane, doppiamente vittime del sistema coloniale e patriarcale, possano rivestire un ruolo attivo e partecipativo.
La ville comme lieu de mémoire : représentations de la ville de Bruges dans “Bruges-la-Morte” (1892) et “Le Carillonneur” (1897) de Georges Rodenbach
Authors: Dineva Elena
Published: November 2023

Cet article se propose de tracer l’image de la ville de Bruges, telle qu’elle se présente dans les deux romans de l’écrivain belge Georges Rodenbach Bruges-la-Morte (1892) et Le Carillonneur (1897). En revêtant l’aspect d’un personnage principal à part entière, la ville de Bruges participe aux parcours mnémoniques des deux protagonistes, le veuf Hugues Viane et le jeune architecte Joris Borluut, qui devient le carillonneur de la ville. Il s’agit d’une image complexe à l’intérieur de laquelle la cité flamande se manifeste d’abord comme un espace symbolique que les protagonistes explorent, s’approprient, intériorisent et qui ne cesse de tenir en éveil leur mémoire individuelle. Bruges sera ensuite évoquée comme une scène de conflit entre l’ancien et le nouveau, autrement dit entre, d’une part, l’ordre préétabli et immuable qui gère la vie des deux hommes, et, d’autre part, tous les éléments perturbateurs qui cherchent à s’y infiltrer pour déstabiliser leur équilibre affectif. Enfin, analysée à travers le prisme de la mémoire, la cité flamande sera définie comme un espace fortement féminisé dont les caractéristiques principales nous tenterons de mettre en évidence dans la dernière partie de cet article.

Published: November 2023

The harvesting of fruits at different developmental stages until maturity may influence their antioxidant activities. Therefore, thepresent study aimed to investigate the changes in total phenolics, flavonoid contents, and in-vitro antioxidant activities in methanolseed extracts of Azadirachta indica A. Juss at different maturity stages (raw, ripe and overripe). All the tested biochemical parametersvaried significantly with maturity stages (p < 0.05%). Total phenolics [mg gallic acid equivalent (GAE)/g dw] and flavonoids contents[mg quercetin equivalent (QE)/g dw] were highest in ripe (33.7 and 0.28, respectively) followed by raw (19.4 and 0.16, respectively)and least in overripe seeds (12.9 and 0.15, respectively). 2, 2-Diphenyl-1-picrylhydrazyl (DPPH), 2, 2-Azino-bis 3-ethylbenzthiazoline-6-sulfonic acid (ABTS) and ferric reducing antioxidant power (FRAP) activities in methanol seed extracts [μM ascorbic acid equivalent(AAE)/g dw] varied between 83.6–106.5, 68–93.8 and 44.8–177.9, respectively. IC50 values (mg/mL) for overripe, raw and ripe seedmethanol extract were 0.60, 1.11, and 2.10, respectively. The study concludes that seeds of A. indica were rich in natural phenolics andalso possess significant antioxidant activities. Thus the present study suggested that fruit industries should harvest ripe fruit seeds ofA. indica to meet out the need of natural phenolics for health benefits of local people.

Published: November 2023

İlkokula başlamak çocuk için önemli dönüm noktalarından biridir. Çocuklar, ilkokula başlarken yeni bir sosyal ortama uyum sağlamaya çalışır. Bunun yanında, kendilerinden okuma yazmayı öğrenmeleri ve temel akademik becerileri kazanmaları beklenmektedir. İlk okuma yazma süreci sadece çocuk için değil aileler için de zorlu geçebilmektedir. Bu durum anne ve babaların bu süreçte ortaklaşa hareket edebilmelerini ve aralarındaki iş bölümünü ifade eden “birlikte ebeveynlik” kavramını karşımıza çıkarmaktadır. Araştırmanın amacı, çocukların okur yazar olma sürecinde ailelerin birlikte ebeveynlik deneyimlerini ortaya çıkarmaktadır. Okul öncesi dönemde erken okuryazarlık süreci, ilkokulda ise ilk okuma yazma süreci bağlamında ailelerin birlikte ebeveynlik deneyimlerini ortaya çıkarmak hedeflenmiştir. Araştırmada, nitel araştırma yöntemlerinden fenomenolojik yaklaşım benimsenmiştir. Bu kapsamda, çocuğu ilkokulda öğrenim gören 40 ebeveyn ile yüz yüze görüşme yapılmıştır. Veri toplama araçları olarak, yarı yapılandırılmış görüşme formu kullanılmıştır. Verilerin analizinde öncelikle veriler sadeleştirilmiştir. Ardından veriler kategorileştirilmiş ve sonuçlar doğrulanmıştır. Araştırma bulguları genel olarak değerlendirildiğinde ilkokula hazırlık sürecinde çocuk bakımı, okul etkinlikleri gibi sorumlulukların genel olarak annede olduğu görülmektedir. Annenin çalıştığı durumlarda anne ve babanın iş yoğunluğu benzer seviyede olmasına rağmen ev içi sorumlulukların, çocuk bakımının ve okul etkinliklerinin çoğunlukla annede olduğu babanın ise destekleyici rolde olduğu görülmektedir. Buna karşın anne ve babanın aralarındaki paylaşımın adil olarak görülmesi toplumsal cinsiyet rolleri ile ilişkili olabilir. Ancak bu durum özellikle okuma yazma sürecinde annenin kendisini yorgun hissetmesi, çocuğa karşı tahammülünün azalması gibi sonuçlar ortaya çıkarmaktadır. Bu nedenle çocuğun okur yazar olma sürecinde baba desteğine duyulan ihtiyaç çok açıktır. Araştırma sonuçlarından hareketle hem anne hem babayı okuma yazma sürecine dahil etmeye yönelik müdahale çalışmalarının yapılması önerilmektedir.
A coleção invisível dos espelhos de Versalhes
Authors: Chaimovich Felipe
Published: November 2023

O Museu Nacional de Versalhes possui a coleção dos primeiros tipos de espelho cujos reflexos foram descritos como quadros por La Font de Saint-Yenne, em 1747. Trata-se dos espelhos feitos com chapa de vidro fundido, técnica datada do final do século XVII que permitiu reflexos mais amplos do que os obtidos anteriormente com espelhos de placa de vidro soprado. O artigo analisa como o emprego de espelhos murais em Versalhes tornou-se um padrão da arquitetura interior francesa, no século XVIII, e como os textos do período descrevem a recepção de seus reflexos. A designação das imagens refletidas como quadros por Saint-Yenne, identificando uma crise da pintura francesa de história devido à substituição de quadros por espelhos, conceitua a experiência inaugural de arte contemporânea, pois as pessoas refletidas passam a agir como imagem. Entretanto, tal dimensão inaugural da coleção de espelhos murais de Versalhes permanece invisível ao público atual da instituição. A situação desse patrimônio esclarece desafios da incorporação da arte contemporânea a acervos de museus.
As cartas chilenas de Mario Pedrosa
Authors: Villas Bôas Glaucia
Published: November 2023

Catálogos, artigos e teses avaliam que a criação do Museu de Solidariedade Salvador Allende/MSSA, localizado em Santiago do Chile, ocorreu devido à solidariedade de artistas, críticos, e historiadores que contribuíram para o envio de obras de arte à capital chilena em apoio ao governo socialista de Salvador Allende (1970/1973). A leitura da correspondência de Mário Pedrosa, durante seu exílio no Chile, naquele período, sugere, entretanto, que a obtenção das obras no exterior, não só dependeu da autoridade que o crítico desfrutava nos meios artísticos internacionais como do enfrentamento de dificuldades e obstáculos políticos e institucionais. A documentação guardada no arquivo do MSSA, inclui as missivas de Pedrosa para Miró, Calder, Argan, Penrose, Brett, Szemann, Amaral, Ashton, Hélio Oiticica, Antônio Dias, entre muito outros. Através de intensa correspondência, Pedrosa impulsionou uma rede de sociabilidade, volumosa, diversa e heterogênea, espalhada por diversos países, cuja movimentação não ocorria sem incompletudes, acasos, surpresas e contingências. Argumento que a solidariedade expressa nas obras enviadas para a criação do acervo do MSSA resultou de uma negociação rara no mundo artístico, faceta original das relações entre arte e política que deu corpo à instituição.

Published: November 2023

The Mannheim Gridshell, Germany, is one of the world???s most important buildings of lightweight architecture. Its free-form shape and large span are impressive features of its filigree construction. With this extraordinary structure, Pritzker Prize winner Frei Otto created an experimental
building that in many respects pushed the boundaries of engineering and is still unparalleled up to the present day. Originally planned as a temporary structure, it has survived the test of time and due to its uniqueness has gained a reputation as a cultural monument of outstanding significance.
However, the years have taken their toll on the structure. The roof supporting structure shows noticeable deformations, and major damage has been detected, making comprehensive renovation necessary in order to ensure long-term preservation of the building. The engineering firm Fast +
Epp has taken on the challenges of the supporting structure. With a sensitivity to the monument, a balance must be struck between making the necessary reinforcements and repairs while preserving the character of the building.
Pulp ‐ Studio‐Based Research in Thin‐Shell Cast Paper Structures
Authors: Davidson Stephanie , Rafailidis Georg
Published: November 2023

This paper reflects upon a sequence of seven research studios, taught within a six-year timespan in three different architecture schools, in which we developed approaches to casting thin-shell (monocoque) paper structures at full scale. Processes of material selection and material harvesting/processing,
formwork design and fabrication all informed the formal expression of the shells. In the context of architectural education, fabricating at full-scale can make structural principles accessible, but large constructions can be expensive for students, and can also create unnecessary material
waste. This sequence of studios, called PULP, allowed students to fabricate spatial structures at full-scale using materials available at little to no cost. The large structures have the potential to biodegrade completely, creating no landfill waste, and no adverse impact in their final resting
place. The dearth of research or precedents in cast‐paper‐as‐structure offers a unique opportunity for novel, basic or “blue skies” research in this area. Processual knowledge gained through leading this studio‐based research over several years has allowed
us to focus more recent research on scaling-up and using material combinations and fabrication techniques that are simple and effective. The increasingly focused investigations and larger scale of the paper cast structures in the most recent (last two years of) studio research suggests that
there is something like a paper-specific formal vocabulary in thin shell structures.
Unveiling the Nexus: Exploring the Impact of Corporate Governance on the Financial Performance of Acquiring Companies in the Indian Context
Authors: Satpathy Debi Prasad , Soni Tarun Kumar
Published: November 2023

The study investigates the effect of corporate governance characteristics on the financial performance of 124 Indian-listed companies that have undergone mergers and acquisitions during 2014–2020. It employs several performance measures, such as short-term capital market performance, long-term capital market performance, accounting-based and market-based measures, and firm-level control factors. The study found board size to be a positive and significant factor affecting short-term market performance. Further, it also documents weak linkages with other corporate governance variables like board independence, CEO duality, etc. Regarding control variables, leverage, the company's age, price-to-book ratio, and research and development expenses significantly impact the acquiring companies' financial returns. The study's findings add to our understanding of corporate governance's impact on performance in cases such as mergers and acquisitions.
Air Mass Flow and Pressure Optimisation of a Pem Fuel Cell Hybrid System for a Forklift Application
Authors: Radica Gojmir , Tolj Ivan , Lototskyy Mykhaylo , Pasupathi Sivakumar
Published: November 2023

A study was conducted on the power system of a forklift equipped with PEM fuel cells. A fuel cell assembly relies on several components for proper functioning, and among these, the air compressor holds paramount importance due to its significant energy consumption when compared to other Balance of Plant components. The air supply system, in turn, plays a critical role in ensuring the stable and efficient operation of the entire fuel cell system. To enhance system efficiency, we delved into the impact of varying the stoichiometric ratio of air and air pressure on the validated and optimized power module model. This investigation was carried out under real loading conditions, replicating the conditions experienced by the power module when fuel cells are in use within a forklift. The air compressor, being a pivotal component of a PEM fuel cell system, can be oper-ated at different excess air and pressure ratios, which in turn influence both the fuel cell's performance and the overall efficiency of the power module system. Our research focused on assessing the performance of polymer electrolyte membrane (PEM) fuel cells under different load cycles, adhering to the VDI60 requirements for forklift applications. This comprehensive examination encompassed the system's minimum and maximum load scenarios, with the primary goal of optimizing excess air and pressure ratio parameters, especially under dynamic load conditions. The results revealed that higher air pressures and lower excess air ratios were con-ducive to increasing system efficiency, shedding light on potential avenues for enhancing the performance of PEM fuel cell systems in forklift applications.

Published: November 2023

Abundance and distribution information of fish in reservoirs is fundamental for efficient fishery management and conservation. However, habitat characteristics of large reservoirs usually make the traditional survey techniques impractical in acquiring these information. In this study, we investigated diurnal and vertical distribution of fish abundance and size composition in the middle section of the Danjiangkou Reservoir through hydroacoustic survey. Fish abundance estimated at night was 4.97 times of that during day. Fishes were highly concentrated in the water-depth layers between 10 and 20 m at night and scattered evenly across whole water column during day. Fish was highly dominant by individuals smaller than 5.5 cm total length (TL) at night and by individuals between 6.2 and 7.8 cm TL during day. Size composition was constant across depth between 10 and 25 m at night and between 15 and 25 m during day, while the proportion of small-sized fish was higher than in the other water-depth layers. Our results indicated an intensive diurnal movement of fish in the reservoir which provides basic information for efficient fishery management on juvenile fish in the littoral zone during day and the diurnal movement pattern in the reservoir suggests that hydroacoustic surveys should be conducted at night for accurate abundance estimation in large reservoirs.Keywords: Depth preferences, Diurnal distribution, Hydroacoustic survey, Reservoir, Size composition

The shrimp scad Alepes djedaba (Forsskal, 1775) belonging to family Carangidae is one of the important components of trawl bycatch landed at Ratnagiri, Maharashtra. Length-weight relationship, condition factor, morphometrics, feeding and reproductive biology of the species was investigated in the present study. Length-weight relationship indicated isometric growth in males, females and pooled individuals. All morphometric characters showed a moderate to high degree of correlation with total length. The qualitative and quantitative analysis of food revealed that A. djedaba is a carnivorous fish feeding mainly on Acetes spp., small fishes, copepods and shrimp larvae. The male:female sex ratio was found to be 1:0.85. Higher gonadosomatic index (GSI) values for females were observed during post-monsoon season. The ova diameter study indicated that A. djedaba follows a protracted spawning season with the individual spawning twice in a season. The absolute fecundity ranged from 15004 to 640800 eggs with an average of 309916 eggs. Length at sexual maturity for female fish was estimated to be 149 mm.Keywords: Arabian Sea, Feeding biology, Pelagic fish, Spawning season, Tropical fish

Comparative efficiency of three different packing materials for post-packaging decontamination of yellowfin tuna Thunnus albacares steaks using pulsed light (PL) technology was investigated during the study. The packing materials used were 300 gauge low density polyethylene (LDPE), 12 Âµ polyester 300 guage polyethylene (PEST/PE) and 300 gauge cast polypropylene (CPP). Inactivation curves were plotted separately for each material for pulsed light exposure time ranging from 0 to 12 s. The curves were fitted with three different models viz, (i) log-linear, (ii) log-linear with Geeraerd and (iii) log-linear with Weibull model and corresponding goodness-of-fit statistics were estimated. Considering the least treatment time for achieving log microbial reduction, CPP was found to be the ideal choice among the three packaging materials. Among the three models, considering the lowest root-mean-square error values (0.0291, 0.0210 and 0.0141 for samples packed in LDPE, PEST/PE and CPP respectively), Weibull model was found to be most appropriate for describing the inactivation curves in all sample cases. Therefore, inactivation curves of steaks packed in CPP was validated with the Weibull model. The corresponding root-mean-square error (0.1036) and correlation coefficient (0.9974) showed that this model can be effectively utilised for modelling the microbial inactivation kinetics using pulsed light technology.Keywords: Cast polypropylene, Inactivation kinetics, Non-thermal processing, Pulsed light technology, Statistical modelling, Yellowfin tuna

Ambiguity regarding the identification of Indo-Pacific sergeant Abudefduf vaigiensis (Quoy and Gaimard, 1825) was sought out through classical taxonomic approach along with molecular confirmation. DNA barcoding of 650 bp region of the Cytochrome C oxidase 1 gene revealed the confirmation of taxonomical identity of the species from the region. Length-weight relationships and relative condition factor in A. vaigiensis were investigated on the samples collected from the south-east coast of India, Gulf of Mannar, to assess the significance of allometric factor and the wellbeing. A total of 360 fishes were collected for the study and categorised into four groups namely males, females , fishes with morphologically undifferentiated gonads (unsexed) and overall pooled samples. Among 360 fishes, 154 were males and 88 were females and the remaining 118 were categorised as unsexed. The analysis was based on fish samples with total length (TL) ranging from 83 to 150 mm and weighing 12.5 to 62.5 g. Length-weight equation and regression coefficient obtained for males, females, unsexed and pooled fishes were W = 0.06 L2.55 (R2 = 0.82); W = 0.02 L2.94 (R2 = 0.88); W = 0.04 L2.68 (R2 = 0.96) and W = 0.04 L2.67 (R2 = 0.92) respectively. The regression parameter â€˜bâ€™ obtained in all the cases were below 3, indicating negative allometric relationship of length and weight. Relative condition factor (K) among pooled fishes showed a value above 1, which indicates better condition of fish. The results of the present study showed that the existing hydrobiological conditions of the Gulf of Mannar area were conducive for food availability, free movement, feeding and better growth of the fish. The present study is also the first report on the molecular confirmation of the species from Indian waters and its morphometry from south-east coast of IndiaKeywords: COI sequencing, Indo-Pacific sergeant major, Length-weight relationship, Relative condition factor, South-east coast of India

The aim of this research was to compare the biochemical parameters of seminal plasma of the rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta fario) cultured in Laribal trout fish farm, Dachigam, Kashmir. During the study period, seminal plasma of rainbow trout was found to contain 73.99Â±1.18 mg dl-1 glucose, 2.22Â±0.17 g dl-1 total protein, 15.65Â±0.84 mg dl-1 triglycerides, 3.07Â±0.27 mg dl-1 cholesterol and 30.87Â±0.65 mg dl-1 urea, whereas in brown trout seminal plasma had 82.27Â±0.52 mg dl-1 glucose, 1.35Â±0.11 g dl-1 total protein, 10.66Â±0.43 mg dl-1 triglyceride, 1.65Â±0.14 mg dl-1 cholesterol and 33.30Â±0.89 mg dl-1 urea. The results revealed that total protein, triglycerides and cholesterol were higher in rainbow trout than the farmed brown trout. On the contrary, concentration of glucose and urea were found higher in farmed brown trout. These findings give us an idea on the effect of environment on milt quality of the two species of trouts. The higher concentration of urea and glucose in the milt of brown trout is an implication of its lower productivity under farmed conditions in Kashmir as compared to rainbow trout.Keywords: Biochemical parameters, Brown trout, Milt quality, Oncorhynchus mykiss, Raibow trout, Salmo trutta fario, Seminal plasma

This study is based on the examination of gut contents of 351 specimens of Sardinella longiceps Valenciennes, 1847landed at Veraval Harbour, Gujarat. Feeding intensity of S. longiceps was reduced during spawning season andgradually increased during post-spawning period. The fish was found to be a planktivorous species consuming diatoms, dinoflagellates, zooplankton and unrecognisable matter. Diatoms were the most dominant group followed by zooplankton and dinoflagellates. Unrecognisable matter comprised of mud, detritus and sand particles were observed in the stomach of S. longiceps throughout the study period. Index of preponderance values showed that the diatoms (57.17%) and zooplankton (36.51%) were the major components of the diet.

Brackishwater aquaculture sector is dominated by the exotic vannamei shrimp farming, which is the economic engine of Indian aquaculture. In 2019-20, exports of 12,89,651 t of Indian marine products fetched foreign exchange worth ₹46,662.85 crores and farmed shrimps accounted for about two-thirds of the shrimps exported. Shrimp farming is export oriented and market price often fluctuates widely impacting the profitability significantly. We conducted this study to estimate technical efficiency of the shrimp farmers In Nellore District, Andhra Pradesh State which tops in shrimp aquaculture in the country. The data were collected through structured questionnaire using personal interview from 80 farmers during COVID 2020 pandemic period. The farm specific technical efficiency varied from 75 to 94% with a mean of 93%. The estimates of the discrepancy parameter γ indicated that 93% of the difference between the maximum possible output and actual output were due to differences in technical inefficiencies of farmers Feed and labour are the significant variables compared to other variables. The results indicated that farmers need to be encouraged to apply more feed to increase shrimp production.

High market demand for shark products makes sharks more threatened due to targeted exploitation, bycatch and intensive utilisation. As the top producer and exporter of shark fins, Indonesia must have accurate and detailed trade data as well as proper monitoring of shark utilisation for implementing better management. This study aimed to estimate the body size of sharks based on their fin measurements. Data collection was done in one of the major shark landing sites at Tanjung Luar Fishing Port (Lombok, West Nusa Tenggara) during 2018-2020. Morphological measurements were taken for economically important and CITES-listed shark species, i.e. Sphyrna lewini, Sphyrna mokarran, Carcharhinus longimanus, Alopias pelagicus, Alopias superciliosus, Isurus oxyrinchus and Isurus paucus caught by both longlines and gillnets. Linear correlations were found in the relationships between body size (total length) and fin sizes (dorsal fin length, dorsal fin height and pectoral fin length), with variations among species. The results of this study will be useful for fishery and quarantine officers in predicting the body size of sharks caught from Indonesian waters and entering the fin trade, as an alternative approach in monitoring sharks as traded commodity, based on fin products.

The present study established the fish body and otolith dimension relationships of flathead sillago Sillaginopsis panijus (Hamilton, 1822), to assist the interpretation of growth. A total of 413 specimens were collected fortnightly from September 2018 to August 2019 off north-western Bay of Bengal. The samples ranged between 142–394 mm in total length and16-413.1 g in total weight. With fish growth, positive correlation was observed between the fish and otolith morphometric parameters. The highest coefficient of determination (R2) was observed between total length and otolith weight (R2=0.9198), followed by otolith weight and otolith width (R2=0.896). These results provide baseline information on the dimensional relationship between fish length and otolith size of this species in Indian waters, which will be helpful in future study on the food and feeding habits, growth and stock structure. Keywords: Coefficient of determination, Correlation, Growth rings, Life history, Morphometry, Sagitta
