Plastic pollution has become a global issue nowadays. Due to the increased population in developing countries, we largely depend on fish from our aquaculture industry meet required protein demand. Though several studies documented plastic ingestion freshwater and marine organisms, very limited have been conducted elucidate microplastic (MP) contamination commercial feed. Therefore, this study was designed identify, quantify, characterize microplastics (MPs) feeds Bangladesh assess possible...
Plastic pollution is ubiquitous in marine and freshwater environments. Tilapia Oreochromis niloticus one of the most important cultured fish species South Asia. However, limited research has been conducted on impact hazard risk assessment microplastic (MP) tilapia. This study characterized ingested MPs identified potential sources gastrointestinal tracts (GTs) farmed tilapia their health assessment. GTs 36 samples were collected from 12 farms Noakhali District, Bangladesh. A total 199...
Abstract The quality of frozen/thawed fish sperm is generally lower than that fresh sperm. Extremely low temperatures are associated with damage to spermatozoon subcellular compartments and molecules such as DNA proteins. Cryodamage can negatively affect integrity, metabolism motility, consequently impairing fertilization embryo development. To preserve efficiently, the addition proteins including seminal plasma proteins, antioxidants, antifreeze glycoproteins, bovine serum albumin before...
Microplastic pollution is becoming an increasingly severe environmental problem. As compared to the marine ecosystem, freshwater ecosystems at high-altitude, remote regions are less studied and lag far behind. Thus, present study aims highlight this issue fill gap in regard. The presence of microplastics (MPs) surface water gastrointestinal tracts (GITs) brown trout (Salmo trutta) from Lake Mahodand, Kalam Swat, Pakistan, a high altitude 2865 m above sea level was investigated. For...
Abstract Short‐term storage of fish sperm is a simple and cost‐effective process in fishery research from basic to applied perspectives. It has been used elucidate evaluate gamete biology quality, perform vitro fertilization, develop cryopreservation. Sperm short‐term selective breeding, hatchery production advanced molecular investigations such as disease detection commercial species aquaculture well biological conservation threatened or endangered fishes. Several studies have demonstrated...
The bacterial population plays a crucial role in recycling the organic matter and metabolizing toxic nitrogenous compounds under biofloc technology (BFT). has been successfully implemented for several fish species, but not shrimp culture Bangladesh. major objectives of this study were to determine effects stocking density on growth performance tiger Penaeus monodon (BFT) rearing system using commercial probiotics investigate abundance total heterotrophic bacteria (THB) vibrio-like (VLB)...
Soil salinity is a global problem that has adverse effects on both agriculture and aquaculture production. The main objectives of this study were to observe the distribution pattern soil in accreted non-accreted land Noakhali district determine intensity at different depths (1-2 cm, 15-20 45-60 cm). samples from 60 sampling sites analyzed measure electrical conductivity (EC). two-way factorial ANOVA model revealed significant effect depth (p < 0.001) locations salinity. After decomposition...
Rainbow trout Oncorhynchus mykiss has a great nutritional value and delicious taste. A 90-days experimental trial was conducted to investigate the effect of dietary leaf extract neem tree Azadirachta indica as feeding supplement on growth performance proximate composition O. mykiss. Four diets were designed T1 (with 5% A. extract), T2 7% T3 10% T4 (control group feed with regular diet 0% extract). The average initial weight fry 0.4 ± 0.14 g stocked at 25 fish/tank two replicates per...
Soil quality is an important factor in fish pond productivity as it controls bottom stability, pH of overlying water and concentrations plant nutrients required for the growth phytoplankton. A satisfactory site constructing fishponds that where soil very deep with neutral pH, weather infiltration low; mineralization organic matter takes place rapidly. The present study was carried out to assess different parameters aged ponds find relationship between parameters. Three groups (1-5 years,...
Metal contamination in surface water urban cities has become a common scenario underdeveloped and developing countries. Nowadays, the extent of this is suspected to be traced remote islands due transportation metals with downward flow. Unfortunately, we found dearth research on our island, where thousands people live use for their daily needs. The current study aims investigate status heavy from Hatiya Coast, determine existence risks human health. Ten samples were collected, concentrations...
Heavy metal (Cu, Zn, Cd, Pb and Fe) concentrations in salt marsh sediments of the Karnafully River coast were investigated this study. Sediment samples four different sites analysed for selected heavy metals by AAS (atomic absorption spectrophotometry). The mean values 45.79 µg/g Cu, 105.0 0.43 26.70 3297.38 Fe It is observed that Cu have positive correlations (r = 0.370, P < 0.05) Zn negative -0.729, correlation matrix. Except Fe, all found at contamination levels which may indicate a...
Abstract The egg structure of sturgeon is complex, with multiple micropyles and an envelope different from that teleosts other fish groups. In the sturgeon, adhesive layer in follicular epithelium responsible for adhesiveness. This a problem artificial reproduction many species, including when large number eggs are incubated hatchery conditions. Although several techniques removing adhesiveness have been developed successfully applied to common carp, tench, pikeperch European catfish,...
