Tratamiento con artroplastía de anquilosis de la articulación temporo mandibular en un paciente con artritis reumatoide. Reporte de un caso.
Authors: Miranda Hernández Blanca , Miranda Villasana José Ernesto
Published: September 2022

La anquilosis de la Articulación Temporo Mandibular (ATM) es un proceso degenerativo que implica una limitación de la apertura bucal, ocasionando trastornos en la alimentación, desarmonías oclusales, obstrucción de la vía aérea y en personas en desarrollo produce asimetrías faciales. Los factores etiológicos son multifactoriales entre los que encontramos traumatismos, infecciones, enfermedades inflamatorias, radioterapia, microsomia, tumoraciones, aunque también puede ser congénita, siendo el trauma la causa  más común.La Artritis Reumatoide (AR) es una enfermedad sistémica, crónica, autoinmune e inflamatoria que afecta preferentemente articulaciones diartroidales y frecuentemente una gran  variedad de órganos. La artritis reumatoide (AR) se presenta  en todo el mundo,  no tiene predilección étnica y se presenta en un 0,3 a 1,5% de toda la población. Las mujeres se afectan 2:3 veces más  que los hombres, en una edad entre la cuarta y sexta década de la vida; si se presenta antes se le llama Artritis Reumatoide Juvenil (ARJ) 1,2. La ATM esta involucrada en el 50 a 60% de los pacientes con AR un año posterior al comienzo de la enfermedad generalizada.3,4Se presenta el caso de paciente femenino de 39 años de edad, con AR y limitación de la apertura bucal de 4mm, que le ocasionó un estado de desnutrición, bajo tratamiento por los Servicios de Reumatología y  Cirugía Maxilofacial se realizó procedimiento quirúrgico de artroplastía bilateral y coronoidectomía unilateral izquierda, obteniendo las paciente una apertura bucal de 31 mm post operatorios; teniendo un control a 18 meses con la misma apertura bucal sin presentar recidiva.

Authors: Gómez Arenas Antonio , Marichi Rodríguez Francisco , Ruiz Díaz Roberto , Aguirre Rebeca
Published: September 2022

La función del Sistema Masticatorio se encuentra relacionada entre otros aspectos con las características de la configuración oclusal. Se han descrito a través de los años diferentes concepciones de la oclusión, hasta llegar a los conceptos de Oclusión Funcional actualmente utilizados.  Se han establecido características comunes de oclusiones consideradas ideales o normales, sin embargo en la actualidad diversos autores concluyen que las características oclusales son específicas de cada individuo. El objetivo de este estudio fue determinar el relieve coronal vestibular de ambas arcadas a través de la medición de la rotación de las coronas dentales presentes en una población mexicana sin tratamiento de ortodoncia con una oclusión considerada normal. En 110 modelos de estudio se midieron las rotaciones de las coronas dentales. Se utilizó un aparato y un aditamento que permiten la medición de superficies dentales empleando un rayo láser. Los resultados muestran un patrón similar en las rotaciones entre el lado derecho e izquierdo de una misma región (mandibular y maxilar). Todas las rotaciones promedio de los dientes de la mandíbula midieron entre -1° y 1°. En cambio, la rotación promedio de los dientes maxilares fluctuó entre -2° y 8.5°. En ambas regiones, el central, el lateral y el canino tuvieron una rotación promedio negativa a diferencia de los premolares y molares que presentaron una rotación promedio positiva. Los molares superiores e inferiores presentaron mayor desviación estándar. Se concluye que debido a la variación observada en la rotación coronal no es adecuado estandarizar sus valores para realizar los tratamientos de ortodoncia, por lo que la utilización de aparatología con prescripción individualizada es más conveniente.

Here the fly-ash is mixed with Cold setting resin at different proportions and water treated at different temperatures to find out a solution to the brick industry. The compressive strength, Hardness, water absorption, Density and thermal conductivity of the fly ash-resin powder bricks obtained under optimum test conditions are 11.24MPa, 47.37HV, 19.09% 1.68 g/cm3, and 0.055 W/mK respectively. The sliding wear behavior is also investigated. The structure-property correlation of these composites is studied using X-ray diffraction, FTIR analysis and scanning electron microscopy
Literature Review on Effects of Saturation on Soil Subgrade Strength
Authors: Ali Bashir
Published: September 2022

Abstract: Subgrade is the layer of soil on which the subbase or pavement is constructed, give support to the remaining part of the pavement system. It is critical for highway engineers to begin a subgrade with a California Bearing Ratio (CBR) value of at least 10. Lot of Researches shows that if a subgrade has a CBR value less than 10, the subbase material will divert under traffic loadings in the same way as the subgrade and cause pavement degradation. The subbase, the layer of aggregate material just below the pavement, gives drainage and stability to the pavement. Undrained water in the pavement substantiate layers can freeze and expand, rising internal pressures on the pavement structure. Additionally, flowing water can move soil particles that clog drains and, in fusion with traffic, pump fines from the subbase or subgrade. It is therefore essential that highway engineers develop a strong, permeable subbase with longitudinal subdrains. This paper provides a literature review on effects of saturation on soil subgrade strength.

Published: September 2022

The website for new student admission is a medium for promotion and registration at the STMIK Amik Riau campus. Currently, the website already has several criteria from the knowledge management system but has never been analyzed. The criteria that already exist on the STMIK Amik Riau website are Repositories, Access and Authentication Layer, Application Layer, Collaborative Intelligence & Filtering. Although the STMIK Amik Riau admission website already has several knowledge management criteria, this website still finds several problems, including between users who do not know what happened when the incident occurred. Then The College Database Section, The Finance Section and The Academic & Student Administration Section often mismatch new student data. For this reason, it is necessary to add criteria, namely the Interfaces Layer, where it stores problems that occur on the website or on the knowledge sharing. However, before adding knowledge sharing, an analysis was carried out using SECI. From this analysis, it can be seen that the admission website users are ready to apply knowledge sharing later.

Published: September 2022

Patagonia is an understudied area, especially when it comes to
population genomic studies with relevance to fishery management.
However, the dynamic and heterogeneous landscape in this area can harbor
important but cryptic genetic population structure. Once such
information is revealed, it can be integrated into the management of
infrequently investigated species. Eleginops maclovinus is a
protandrous hermaphrodite species with economic importance for local
communities that is currently managed as a single genetic unit. In this
study, we sampled five locations distributed across a salinity cline
from Northern Patagonia to investigate the genetic population structure
of E. maclovinus. We use Restriction-site Associated DNA
(RAD) sequencing and outlier tests to obtain neutral and adaptive loci,
using FST and GEA approaches. We identified a spatial pattern of
structuration with gene flow and spatial selection by environmental
association. Neutral and adaptive loci showed two and three genetic
groups, respectively. The effective population sizes estimated ranged
from 572 (Chepu) to 14,454 (Chaitén) and were influenced more by
locality than salinity cline. We found loci putatively associated with
salinity suggesting that salinity may act as a selective driver in
E. maclovinus populations. These results suggest a complex
interaction between genetic drift, geneflow, and natural selection in
this area. Our findings suggest several units in this area, and the
information should be integrated into the management of this species. We
discuss the significance of these results for fishery management and
suggest future directions to improve our understanding of how E.
maclovinus is adapted to the dynamic waters of Northern
Patagonia.

Published: September 2022

Left atrial myxoma is the most common variant of cardiac tumour, rarely
presenting with systemic embolization involving 3 limbs and intra
cranial bleed simultaneously. Our case aims to discuss appropriate
management strategy in such cases. This case presents a 34 year old lady
with acute limb ischemia both lower limb and right upper limb with
intracranial bleed with no signs of congestive heart failure diagnosed
with LA Myxoma on preoperative routine 2d ECHO cardiography. She
underwent embolectomy of right brachial artery and bilateral femoral
artery, common iliac artery and abdominal aorta with excision of LA
Myxoma planned for 4 weeks later. In patients presenting with acute limb
ischemia and intracranial bleed, the definitive surgery of LA myxoma
excision should be postponed for 4 weeks to prevent risk of systemic
heparinisation causing worsening of neurological functions while acute
limb ischemia should be addressed immediately.
A qualitative assessment of alternative eradication strategies for African swine fever in the Dominican Republic
Authors: Schambow Rachel A. , R Reyes , Morales J. , Diaz A. , Perez Andres
Published: September 2022

Since the first outbreak was identified in July 2021, the African swine
fever (ASF) epidemic in pigs in the Dominican Republic (DR) has
generated much discourse on various measures for its control. Strategies
range from complete depopulation of the swine population, as was done in
1978, to a system of passive surveillance with endemicity, with many
in-between. Currently, ASF-decision makers need an evaluation of these
potential strategies that incorporates both private and public
perspectives. To achieve this goal, we used strengths, weaknesses,
opportunities, and threats (SWOT) analysis to evaluate three different
theoretical ASF control scenarios with the aim of contributing to the
discussion of different alternatives to mitigate the epidemic’s impact.
These included total depopulation of all pigs in the DR, partial
depopulation, and continuation of current control measures. Relevant
experts from the DR private swine industry sector were identified
through “snowball sampling” techniques. First, relevant stakeholders
within the DR private swine industry were asked to identify individuals
that they would consider experts for ASF in the DR. Experts identified
through this process were contacted to participate. Of these, 5 experts
completed the SWOT questionnaire for each of the scenarios, with
additional questions considering aspects of financial cost, social
impact, feasibility, animal welfare, and regional policy. The responses
were summarized for an overall evaluation of each scenario and presented
to the full group of experts initially nominated for final review and
later to representatives of the DR government for feedback. The SWOT
analysis highlighted that although there are certain benefits associated
with each of the proposed strategies, there are also important drawbacks
and disadvantages for all. This may explain in part why 6 months after
the epidemic was first reported, there are still uncertainty about the
most effective control strategy to be implemented. This analysis is a
tool for discussions at the private-public interface and facilitate
cooperation between the DR government and swine industry. Ultimately,
this work supports the development of strategies that will reduce ASF
burden in the DR in a way suitable for all relevant stakeholders.
Positivity rate, risk factors and symptom characteristics of influenza virus in a tertiary hospital meeting COVID-19, Hangzhou, China
Authors: Wan Jiaxiang , Zhang Ruxuan
Published: September 2022

Background: Following the Coronavirus disease (COVID-19) pandemic, new
changes in the transmission of various pathogens have occurred. The
environmental changes influenced by the COVID-19 pandemic have affected
the flow of human society and the survival environment of other
microorganisms. The prevalence of influenza viruses has also changed
under this selection pressure. Objective: To investigate the influenza
virus’s prevalence, risk factors and symptom characteristics during the
outbreak of COVID-19. Methods: Samples and data were collected from
outpatients requiring respiratory virus tests in a tertiary hospital.
Throat swabs were tested in the immunocolloidal gold method.
Characteristics of influenza A and B compared before and after the
outbreak of COVID-19. Results: The dominant virus strain in 2020-2022
has gradually changed from influenza A to influenza B. Influenza A is
mainly prevalent in 0 to 20 years old (P < 0.05), and
influenza B is dominant in all age groups. Most of the patients with
positive results were from paediatrics and presented in fever clinics
(P < 0.05); Most of the patients were diagnosed with
fever and upper respiratory tract infection (P < 0.05).
Conclusion: The influenza virus’s positive rate, risk factors and
symptom characteristics have changed compared to previous years. It
means the epidemic prevention measures have greatly affected the
prevalence of the influenza virus since the outbreak of COVID-19.
Mitochondrial ATP synthase activity affects plastid retrograde signaling in Arabidopsis

Plastid retrograde signaling plays a key role in coordinating the
expression of plastid genes and photosynthesis-associated nuclear genes
( PhANGs). Although plastid retrograde signaling can be
substantially compromised by mitochondrial dysfunction, it is not yet
clear whether specific mitochondrial factors are required to regulate
plastid retrograde signaling. Here, we show that mitochondrial ATP
synthase β-subunit mutants with decreased ATP synthase activity
are impaired in plastid retrograde signaling. Transcriptome analysis
revealed that the expression levels of PhANGs were significantly
higher in seedlings affected in AT5G08670, the gene of the
β-subunit of mitochondrial ATP synthase than in wild-type (WT)
seedlings upon treatment with lincomycin (LIN) and norflurazon (NF).
Further studies showed that the expression of nuclear genes involved in
chloroplast and mitochondrial retrograde signaling was affected in
AT5G08670 mutant seedlings treated with LIN. These changes might
be associated with the repression of some transcriptional factors (TFs),
such as ARF3/ETTIN ( ETT), PLASTID TRANSCRIPTION
FACTOR 1 ( PTF1), CYCLOIDEA AND PCF TRANSCRIPTION FACTOR
2 ( TCP2), and KOW DOMAIN-CONTAINING TRANSCRIPTION FACTOR
1 ( KTF1). These findings indicate that the activity of
mitochondrial ATP synthase affects plastid retrograde signaling.

This paper empirically examines the impact of defence and security on foreign direct investment (FDI) in Nigeria using quarterly historical data covering the period of 1994q1-2019q4 and an ARDL and VAR econometric techniques are adopted as tools of data analysis. The results from both econometric approaches revealed that foreign direct investment responds negatively to the exogenous occurrence of security threats both in the short and long runs. Also, economic instability and uncertainty are shown to cause drag in foreign direct investment inflow in Nigeria. This study further shows that economic liberalization, proxy with trade openness, and economic progress, proxy with the growth of gross domestic product per capita contribute immensely to the flow of foreign direct investment into Nigeria. The study recommendations drawn from the findings are that national security challenges should be addressed without delay by the government at all the tiers levels to change the course of the downward trend of FDI in Nigeria; establish risk adverting policy to reduce economic uncertainty; promote price stability policy to reduce economic instability; diversifying the economy to further increase economic progress which greatly drives FDI inflow, and encourage economic liberalization which brings benefit through market expansion.

Optimization of micro-channel heat sink based on genetic algorithm and back propagation neural network
Authors: Jiang Meixia , Pan Zhongliang
Published: September 2022

In order to efficiently solve the problem of optimization of the micro-channel heat sink, an optimization strategy combining intelligent algorithms and CFD was proposed. The micro-channel heat sink with the trapezoidal cavity and solid/slotted oval pins was proposed to enhance heat transfer. The aspect ratio, distance from the center of the oval pin to the center of the cavity, and slot thickness were design variables. The thermal resistance and pumping power of the micro-channel heat sink were objective functions. Within the selected range of design variables, thirty groups of uniformly sampled sample points were obtained by the Latin hypercube experiment. The 3-D model was established by SOLIDWORKS software, and the numerical simulation was carried out by using FLUENT soft-ware. The genetic algorithm optimized back propagation neural network to construct the prediction model, and the simulated data of Latin hypercube sampling were trained to obtain the non-linear mapping relationship between design variables and objective functions. The optimal combination of structural parameters of the micro-channel heat sink was obtained by optimization of the genetic algorithm, which was verified by numerical simulation. The results show that the optimization scheme was suitable for getting the optimal value of the structural parameters of the micro-channel heat sink, which provided a reference for the optimal design of the micro-channel heat sink.
Reducing deaerator-related energy losses in steam boilers
Authors: Savas Ahmet , Kocabas Ceyda
Published: September 2022

Improving energy efficiency helps to achieve a more reliable energy supply and a sustainable environment. In the current study, some observations were made in a textile factory to improve the energy efficiency of the industrial steam boiler. Deaerator is one of the main points of energy loss in the boiler. It is possible to reduce energy loss in the deaerator by using today?s scientific and technological possibilities. The failure mode and effects analysis method was used in determining and ranking the factors causing energy loss in the deaerator. Some improvements were suggested based on the data of the failure mode and effects analysis study. The amount of energy loss in the deaerator was calculated by establishing mass and energy balances both in the current situation and after the improvements. As a result, when suggestions were applied, the energy loss in the deaerator, which was 373.6 kW before, could be reduced to 40.4 kW. Also, the net steam production capacity of the steam system will increase by approximately 9%. The pay-back period of the proposed investments was calculated as 2.8 months by performing the economic analysis. The study outcomes revealed that the failure mode and effects analysis technique, which is used as a risk analysis and failure prevention method within the scope of process improvement studies, can also be used to increase boiler energy efficiency.

Published: September 2022

Psoriatic patients with latent tuberculosis infection and properly treated active tuberculosis need careful management when prescribing modern biological drugs. Although data and guidelines regarding tumour necrosis factor-α inhibitors advise caution and initiation of prophylactic therapy in patients with latent tuberculosis infection, the same indications do not seem to find equal force for interleukin (IL)-23 and IL-17 inhibitors. In order to evaluate the risk of reactivation in patients with latent tuberculosis infection or properly treated active tuberculosis, an observational retrospective study was conducted on the population referred to our centre at Dermatologic Clinic of University of Turin, Italy. In the last 10 years at the clinic 19 psoriatic patients were found to be at risk of tuberculosis reactivation: 10 patients were QuantiFERON- TB-positive at baseline, 2 became positive during treatment, 6 reported prior tuberculous infection, and 1 was QuantiFERON-TB-negative at baseline and developed disseminated tuberculosis during treatment with anti-tumour necrosis factor-α. Overall, 10.5% of this group of patients developed active tuberculosis; however, stratifying by biologic therapy, zero cases were observed among patients treated with anti-IL-17, -23, or -12/23 over a relatively long follow-up (48.1 months) A review of the available literature following our experience confirms the increased risk of tuberculosis reactivation with tumour necrosis factor-α inhibitors. Concerning anti-IL-23 and IL-17 drugs, available data showed high safety in patients at risk of tuberculosis reactivation. Screening of patients who should be taking IL-17 and IL-23 inhibitors is recommended for public health purposes. In case of a positive result with these therapies, consulting with an infectious diseases specialist is suggested in order to weigh up the risks and benefits of prophylactic treatment.
Seiches in the Semiclosed Seas of the Continental Shelf
Authors: Yu Inzhebeikin
Published: September 2022

Seiche movements in two small areas of semi-closed seas on the Continental Shelf (the White Sea and the Sea of Azov) with very different morphometric characteristics are considered in this paper. In addition, tidal movements are highly developed in the White sea, while in the Azov sea tides are virtually absent. We’ve used morphometric characteristics of the seas, including the ones recently obtained by the Azov Sea, as well as methods of numerical hydrodynamic simulation based on the theory of shallow water, and spectral analysis of the observation data of the sea level fluctuations.
Constructed Wetlands for Marine Aquaculture Wastewater Treatment: A New Challenge
Authors: Pérez Leonardo Martín
Published: September 2022

Aquaculture is the fastest growing food production sector worldwide. Global demand for seafood continues to grow, and landbased aquaculture is expected to grow in order to meet the increasing market demand. In this context, marine aquaculture production systems are moving towards land-based farming. However, due to the large volumes of wastewater with high salinity and other fish-metabolism derived pollutants (e.g., nitrogen compounds), it remains a challenge for treatment of effluents from land-based marine aquaculture. In this scenario, development of environmental-friendly and efficient aquaculture effluent treatment system is crucial for sustainable intensification of aquaculture. Owing to low capital, operating costs, and low energy consumption, constructed wetlands (CWs) are becoming a promising technique to treat aquaculture effluents before discharge.
Lepas Lalandii sp. Nov: A Goose Barnacle (Crustacea) Species from DNA Barcoding
Authors: S Bezeng Bezeng
Published: September 2022

We analysed DNA based phylogenetic relationships of selected species of pedunculated barnacles, using species from the genus Chthamalus (order: Balanomorpha) as outgroup, to estimate the position of a new species of goose barnacle. Ninetythree individuals from 17 ingroups (including seven genera) and five outgroup species were studied. The pedunculated species included taxa from the order Scalpellomorpha a) superfamily: Lepadoidea (family Lepadidae; genera Conchoderma, Dosima, Lepas and family: Poecilasmatidae; genera Octolasmis and Poecilasma), and b) order Pollicipedomorpha (family: Pollicipedidae; genera Capitilum and Pollicipes). As the ingroup members represent a polyphyletic assemblage, our analysis was limited to estimating the status and the genetic relationship of the new species. We show that Lepas lalandii sp. nov. is monophyletic and a member of the Lepadidae, but separated from other Lepas. Full descriptions of Lepas lalandii sp. nov. will follow detailed morphological studies. This is conceivably the most extensive dataset for the individuals studied.
Evaluation of Haematological and Biochemical Changes in Catfish (Clarias Gariepinus) Fed Ginger Additive Meal Diets
Authors: Kela Esther
Published: September 2022

Clarias gariepinus adults were fed varying levels of ginger additive meal diets (0 mg/g, 25 mg/g, 50 mg/g, 75 mg/g and 100 mg/g), respectively, in order to evaluate their effects on the biochemical and haematological parameters of fish. Blood biochemical analysis was performed at the end of 84 days by taking the portion of the collected blood and was dispensed into non-heparinised tubes. There were significant increases (P < 0.05) in glucose, aspertate transferase, alanine transferase, and sodium concentrations respectively. The activity of potassium, creatinine and serum protein changed in a non-significant (P > 0.05) manner with increasing concentrations of additive diets compared to the control. Although no definite trend in the values of computed biochemical indices was observed. However, glucose, aspertate transferase (AST), alanine transferase (ALT), urea, creatinine, sodium, and potassium increased with varying additive inclusion concentration. Also, Glucose, ALT, AST, Urea, creatinine, sodium and potassium activities of all the fish, which have been fed ginger additive meal diets were significantly higher (p<0.05) in comparison to their respective control. Results also showed that there were increase in the blood parameters of Clarias gariepinus fed ginger additive meal diets compared to the control diet except in mean cell haematocrit (MCV) but were statistically different (p<0.05). Highest Packed cell volume (PCV) of 31.00% were recorded in diet (GD3), White Blood Cell (WBC), 8.00 x 103 in GD2, and red blood cell (RBC) 8.70 x 106; while highest Haemoglobin (Hb), 11.00 g/dl were recorded in fish fed diet GD3. All blood parameters obtained were between the range of recommended fish blood. It is concluded that using ginger as additive feed on Clarias gariepinus showed a slight increase in the haematological parameters compared with the control diet (GD1) except in MCV but it has no negative effect on the health status of the studied fish.
Synergistic Effects of Medicinal Plants Carica papaya, Telferia ocidentalis and Oxytetracyline against some Pathogens Isolated from Clarias Gariepinus
Authors: Olusola Sunday Emmanuel
Published: September 2022

The problem of fish diseases may be due to the development of antibiotic-resistant bacteria and there is an increasing awareness to determine the efficacy of plants as an alternative to treat microbial diseases of aquatic animals. Antibacterial and antifungal synergistic evaluation of methanolic and ethanolic extracts of Fluted Pumpkin Leaves (FPL), Pawpaw Leaves (PL) and combination with oxytetracycline were investigated using the agar cup diffusion and broth diffusion techniques. The extracts were tested against 8 clinical strains of Gram-positive and Gram-negative bacteria and a fungal. Minimum Inhibitory Concentration (MIC) of methanolic and ethanolic extracts of pumpkin, pawpaw leaves and combination with oxytetracycline were determined using standard methods. Data were analyzed using descriptive statistics. The extracts displayed higher antimicrobial properties to the Gram-positive and G negative bacteria and these plants inhibited the growth of all the microorganisms used in the study when combine with oxytetracycline at 10 mg/ml and 30 mg/ml. The diameter of the zone of inhibition of methanolic and ethanolic extracts of fluted pumpkin and pawpaw leaves when combine with oxytetracycline (10 mg/ml and 30 mg/ml) were higher than single application and combination of the two plants with oxytetracycline. The combination of extracts of each plant with oxytetracycline was found to be the most effective combination in retarding microbial growth of all tested pathogenic bacteria The results of MIC of methanolic and ethanolic extracts of pawpaw leaves, fluted pumpkin leaves and oxytetracycline at 10 mg/ml and 30 mg/ml range between 212.5 µg/ml - 850 µg/ml while the control doesn’t show any antimicrobial properties in terms of zone of inhibition and minimum inhibitory concentration. The results observed in the pumpkin and pawpaw leaves and combination with oxytetracycline can provide additive or synergistic inhibitory effects making them more effective as antimicrobial agents against fish pathogens.

Challenge of Aquaculture in Bangladesh during CORONA 19
Authors: Chakraborty Binay Kumar
Published: September 2022

Data and information sources are used from the direct interview with individual, publication of the Department of Fisheries (DoF), internet and related non-published grey literature. The country has an inland water area of about 4.72mill.ha and about 710km long coastal belt. Fisheries sector contributes 3.57% to the national GDP, 25.30% to the agricultural GDP and more than 2.0% to the total export earnings. The target of fish production was crossed by producing 4.28 mill.mt fish in 2017-2018, whereas in 2017-18, inland culture fisheries contribute 56.0% to total fish production. This sector has been contributing about 60% animal protein in daily dietary requirement comes from fish, which is significant in food security through proving safe and quality animal protein. About 162.18 million (11%) people more than of total population are engaged with this sector on full and part time basis for their livelihoods. Bangladesh is blessed with an enriched aquatic diversity, comprising almost 260 freshwater fish species and 740 marine water fish species with other aquatic lives. But due to COVID 19 decline and degradation of wetland resources, the stock of inland capture fisheries has been reduced remarkably. In recent years, the fisheries sector is faced with challenges posed by numerous natural and anthropogenic causes such as climate change, natural disaster, environmental pollution, industrialization, overfishing, using destructive fishing gears, pesticide and agrochemicals and COVID 19. Very recently some important national program and biological management technology is developed for hilsha production, fish production and open water management to restrict the declination of resources and enhance production. But about 11% people are going to be jobless and maximum worker are workless in the country by affecting of COVID 19. The effect of COVID 19 is posing significant threat to the production, income, food security and livelihood of the population.
