Summary: The use of antibiotics, pesticides, and other aqua-chemicals in aquaculture was investigated in the Rajshahi district of Bangladesh through face-to-face interviews with fish farmers. The study revealed a lack of knowledge among fish farmers regarding the effective dosages of chemicals, with a considerable proportion reporting indiscriminate use and ignorance about residual effects. It suggests the need for strict monitoring and control by authorities, as well as further research on detection of residues and their consequences on the ecosystem and human health.

Summary: The impacts of climate change on fish seed production in hatcheries were assessed from the perspective of hatchery owners in Bangladesh. The study found that hatchery owners recognized the evidence of climate change, especially in terms of changes in air and water temperatures, rainfall, sunlight intensity, and frequent natural disasters. The impacts of climate change on hatchery operations were severe, affecting the embryonic and physiological development of fish fry, environmental changes, disease outbreaks, and poor growth of broodfish. Measures such as planting trees, temperature control, increased water supply, and improved aeration can help address the negative impacts.

Summary: The study investigated the submicroscopic structure of male germ cells and spermatogenesis in turbot, revealing interesting findings such as the early formation of sperm tail and the number of mitochondria in spermatozoa. The research also indicated a negative correlation between the vitality of mature sperm and the proportion of sperm deformity.

Summary: This study investigates how Internet use can help improve fish farms' productivity, finding that it can increase productivity, particularly for farmers without access to off-farm work. Additionally, the impact of female heads' Internet use on farm productivity is more significant than that of male heads.

Summary: This article evaluates and compares the use of alternatives assessment in different regulatory frameworks through four case examples. Four lessons regarding the use of alternatives assessments in regulatory policy are identified, and five recommendations for regulatory alternatives assessment are provided. This synthesis provides expert perspectives on the subject, which should be supplemented by formal policy analysis over time to better understand the impact of regulatory alternatives assessment.

Summary: There are growing concerns for food safety in developing countries like Bangladesh, particularly due to the risks associated with heavy metal contamination of culinary herbs and spices. This study analyzes the concentrations of heavy metals in branded and non-branded spices, as well as the health hazards associated with consuming these spices. The findings suggest high levels of lead, cadmium, chromium, copper, and iron in certain spices, which may have adverse health impacts for consumers. The study provides valuable insights into the potential health risks of heavy metal contamination in commonly consumed spices.

Summary: This study investigates the textural characteristics and depositional environments of surficial sediments in the Noakhali coast. The results show a predominance of fine-grained sediments with a unimodal grain size distribution, indicating low to moderate energy deposition. The study suggests limited prospects for finding valuable heavy minerals, except for two locations dominated by sand.

Summary: The study found that disease burden in Bangladesh shrimp farms has been increasing year by year, along with a significant rise in the use of chemical treatments. Farmers reported physical deformities, nutritional deficiencies, and unknown diseases in shrimp stock. Further research is needed to identify potential risks from residues of chemical products.

Summary: This research quantified antimicrobial resistance in E. coli isolates from poultry fecal and environmental samples in Bangladesh and explored their association with antimicrobial use. The study found high levels of acquired resistance against commonly used antimicrobial agents, but no significant correlation between antimicrobial use and resistance. The presence of multi-drug resistance, including against critically important antimicrobials, was also observed. This highlights the urgent need for an antimicrobial resistance/antimicrobial use surveillance program in the poultry production sector of Bangladesh.

Summary: The study found that the average concentrations of six heavy metals in the sediment of the lower Meghna River estuary were ranked in descending order of iron (Fe), zinc (Zn), lead (Pb), chromium (Cr), copper (Cu), and cadmium (Cd). The geo-accumulation, contamination, and pollution load indexes indicated that the estuary was not contaminated by Fe, Zn, Pb, Cr, and Cu. There was a significant correlation between sediment grain size and the association of iron (Fe) and lead (Pb), but no significant correlation was found between other metals and grain size.

Summary: A study in North-central Nigeria assessed fish farmers' practices and perceptions on antimicrobial usage, as well as risk pathways for antimicrobial resistance. Findings revealed widespread self-prescription of antimicrobials and lack of adherence to withdrawal periods, with socio-cultural drivers contributing to misuse and emergence of resistance. Majority of farms were classified as high risk, with residues detected in samples from nearly half of the farms. Promotion of antimicrobial stewardship and control programs are necessary to address these issues for food safety and public health.
