In Bangladesh, as with many countries, the spread of COVID-19 made wearing single-use face masks, a non-pharmaceutical intervention to reduce viral transmission, surge in popularity amongst general population. Consequently, irresponsible discarding used masks into environment, and mismanagement waste they produce, is potentially placing large pollution burden on aquatic ecosystems country. Slow degradation mask-derived polypropylene polyethylene fibres creates reservoirs microplastic...

Food production environments in low- and middle-income countries (LMICs) are recognized as posing significant increasing risks to antimicrobial resistance (AMR), one of the greatest threats global public health food security systems. In order maximize expedite action mitigating AMR, World Bank AMR Global Leaders Group have recommended that is integrated into wider sustainable development strategies. Thus, there an urgent need for tools support decision makers unravelling complex social...

Tilapia lake virus (TiLV), a negative sense RNA with 10 segment genome, is an emerging threat to tilapia aquaculture worldwide, outbreaks causing over 90% mortality reported on several continents since 2014. Following severe event in July 2017, we confirmed the presence of TiLV Bangladesh and obtained near-complete genome this isolate, BD-2017. Phylogenetic analysis concatenated coding regions placed BD-2017 clade two isolates from Thailand, separate Israeli South American isolates. However,...

Phases 1 2 conducted in hapas the same pond, whereas 3 was performed concrete tanks. probiotic administered at a rate 0.2 g kg–1 feed times per day...

The impacts of climate change (CC) on all spheres human life are evident worldwide. Fish is the premier protein source, and its production in Bangladesh mainly dependent hatchery-based seed production. However, hatchery productivity disrupted every year due to CC. This study assesses CC fish hatcheries from perspective owners. A semi-structured questionnaire survey was conducted with 60 owners five sub-districts (Trishal, Mymensingh Sadar, Gouripur, Fulbaria, Muktagacha) district, highest...

In Bangladesh, fish provide over 60% of animal-source food with 56.2% this coming from aquaculture produced predominantly in rural freshwater ponds. Increasing demand for products is driving intensification and resulting higher disease prevalence, posing a risk to security. Biosecurity often absent practices Bangladesh antibiotics are commonly used treat prevent outbreaks. Antibiotics administered incorrectly - key factor associated the development antimicrobial resistance (AMR). AMR can be...

In terms of hatchery-based seed production, one the most important aquaculture species in Bangladesh is stinging catfish (Heteropneustes fossilis). Scientific and evidence-based embryonic larval development research on this fish context climate change limited. This experimental study was conducted via induced breeding using a conventional hatchery system, rearing larvae hapas placed ponds. A series microscopic observations trinocular digital microscope an analysis relationship between growth...

ABSTRACT Hilsa shad ( Tenualosa ilisha ) is an anadromous fish, making the single largest wild fishery in Bangladesh, supporting livelihoods of about 2% population and contributing 1% to national GDP. Several studies reported positive outcomes associated with its catch status, biology, ecology, nutritional profile, conservation management socio‐economic impacts. However, significant knowledge gaps exist hilsa fisheries, particularly areas crucial for research development. In this article, we...

Abstract Background The pondwater microbiome is believed to play a key role in fish health, including shaping mucosal surface microbiomes that help protect against disease. How different physiochemical features relating season, geographical locations, as well crop species shape the pond water finfish aquaculture system, not established. Pangasius ( Pangasianodon hypophthalmus ) and tilapia Oreochromis niloticus are two of most widely farmed disease major impediment expansion their...

Background: This study aimed to investigate structural dynamics, binding interactions, stability, pharmacokinetics, ecological risks, and bioactivity of shrimp receptor protein LVDD9B identify potential therapeutic candidates against White Spot Syndrome Virus (WSSV). Methods: 3D structure was predicted using SWISS-MODEL validated with ProSA Ramachandran plots. Protein-protein docking between VP26 (WSSV protein) performed HADDOCK 2.4 server. Molecular docking, dynamics simulations,...

The use of nanotechnology in food production systems is being investigated globally, though there limited research on its effect fish nutrition. Therefore, this study aimed to identify the effects silica nanoparticles (NPs) nutrition and physiology tilapia, Oreochromis niloticus . Four isonitrogenous diets (300 g/kg crude protein) with NPs (0, 1, 2, 3 mg/kg diet) were fed (6.52 ± 0.20 g) a recirculatory aquaculture system for 56 days. Throughout period, NP survival rate, blood cell count,...

Globally, Bangladesh is the fifth largest aquaculture producer, with pangasius (Pangasianodon hypopthalamus) contributing 18 % of total production. This production characterized by unregulated farming practices, domestic trade without value addition, product development, or export. In this paper, Sustainability Assessment Food and Agriculture (SAFA) framework FAO was used to assess competency Bangladeshi farmers comparing their practices indicators prescribed Aquaculture Stewardship Council...

Integrated aquaculture is an efficient method to address food scarcity and land resources. This study analysed the impacts of integrated rice–prawn–vegetable farms (RPVF) compared with conventional rice (CRF) on farming households in southwest Bangladesh, terms cropping pattern, financial profitability viability, cash-flow. Data were collected through face-to-face recall interviews from farmers CRF RPVF. For RPVF, cultivated diverse produce wet season, such as prawn/shrimp, carps reservoirs...

Farmed freshwater prawn ( Macrobrachium rosenbergii ) and black tiger shrimp Penaeus monodon comprise a significant portion of Bangladesh’s seafood exports, raising concerns about their environmental impacts. Freshwater farms, which require relatively high amount feed supply, release 1.0 MT CO 2 -equivalents/year, equating to 18.8 kg e/MT prawn, contributing significantly global warming climate change risks. Integrated Multi-Trophic Aquaculture (IMTA) offers an alternative farming method...

Herbal extracts have been proven to improve immunity, growth rate and appetite, as well being antihepatotoxic they are important alternatives synthetic antibiotics chemotherapeutics. In this study, Papaveraceae (PE), alkaloids (quaternary benzophenanthridine protopine) source were incorporated into the diet of striped catfish, Pangasianodon hypophthalmus, assess their effects on growth, feed utilisation digestibility, body composition, product quality pathogen response. PE was supplemented...

In recent years, attaining gonadal maturation in smaller Hilsa ( Tenualosa ilisha ) has become a burning issue for fishery of Bangladesh. Causes early are not yet clearly understood. Along with environmental parameters, genetic differentiation within the population was hypothesized as main driver, and therefore, assessing correlation between gonadosomatic index (GSI) factors analyzing diversity were set objectives present study. To address these complex issues, six diverse habitats across...
