ClearMicroplastics in aquaculture ponds of Bangladesh: Source attribution, pollution load, and ecological risk assessment
A survey of aquaculture ponds in Bangladesh's Jashore district found significant microplastic contamination in both surface water and sediments, with fibers and fragments being the dominant forms and polyethylene the most common polymer. The study identifies aquaculture ponds as underappreciated microplastic sinks that may pose risks to farmed fish and ultimately to people who eat them. Given Bangladesh's heavy reliance on pond aquaculture for food security, the findings raise important concerns about the safety of locally farmed seafood.
Impact of training and development on the quality of fish produced: Evidence from fish farmers in Odogbolu, Ogun State, Nigeria
This paper is not relevant to microplastics; it examines the impact of training and education programs on fish farming productivity and fish marketability in Nigeria.
Extended Bibliometric Review of Technical Challenges in Mariculture Production and Research Hotspot Analysis
This paper is not about microplastics; it is a bibliometric analysis of technical challenges in mariculture production, covering cage design, biofouling, feeding, and waste management.
Ecological risk profiling of microplastic load in commercial aquaculture of Bangladesh: A multi-approach analysis across species-specific ponds
Researchers assessed microplastic contamination across five types of commercial fish ponds in Bangladesh, finding an average of about 520 particles per cubic meter of water. Pangas ponds had the highest contamination levels, and polyethylene and polypropylene were the most common plastic types. The study raises concerns about ecological risks to farmed fish in one of the world's leading aquaculture nations.
Evaluating Pollution from Aquaculture Materials and Developing Sustainable Alternatives to Reduce Marine Environmental Impacts: A Case Study in Vietnam
Researchers assessed the status of marine pollution associated with aquaculture activities in Vietnam, with particular emphasis on plastic and microplastic contamination from aquaculture materials, and developed recommendations for more sustainable alternatives to reduce the environmental footprint of coastal aquaculture operations.
Microplastics in freshwater wild and farmed fish species of Bangladesh
Researchers evaluated microplastic contamination in freshwater wild and farmed fish species across multiple rivers and farms in Bangladesh, comparing contamination levels between wild-caught and aquaculture-raised fish of the same species.
Integrated analysis of microplastics origins and impact on prominent aquaculture ecosystems in Bangladesh
Researchers surveyed microplastic contamination in aquaculture ponds in Bangladesh, finding widespread particles in both the water and farmed fish including tilapia and pangas. Fibers were the most common type, likely from textile and fishing net waste, and the contamination levels posed potential health risks to consumers. Since farmed fish is a major protein source in Bangladesh and many developing countries, these findings highlight a direct pathway for microplastics to reach people through their diet.
Occurrences, sources, fate and impacts of plastic on aquatic organisms and human health in global perspectives: What Bangladesh can do in future?
This review provides a comprehensive overview of plastic and microplastic pollution in aquatic environments globally, with a specific focus on the situation in Bangladesh. Researchers compiled evidence on the sources, fate, and biological impacts of plastic pollution on aquatic organisms ranging from plankton to fish, as well as potential human health risks. The study concludes with recommendations for waste management strategies and future research priorities tailored to Bangladesh's specific environmental and economic challenges.
Microplastics in fish culture ponds: abundance, characterization, and contamination risk assessment
Researchers surveyed five types of fish farming ponds in Bangladesh and found microplastics in all sediment and water samples, with higher contamination near industrial areas. The most common microplastics were small fragments and fibers made of polyethylene and polypropylene, likely originating from packaging waste and fishing gear. The findings raise concerns about microplastic contamination in farmed fish that are destined for human consumption.
Risk of aquaculture-derived microplastics in aquaculture areas: An overlooked issue or a non-issue?
This review examines aquaculture-derived microplastics from degrading fishing nets and foam buoys, finding they represent a significant but overlooked source of marine microplastic pollution with distinct environmental consequences compared to other sources.
Climate Change and Current Adaptation Strategies in the Haor Areas
This paper is not about microplastic pollution. It examines how climate change affects fishers in the haor wetland areas of Bangladesh, documenting impacts like altered rainfall patterns, natural disasters, and disease emergence, along with the adaptation strategies fishers use to cope.
Microplastics occurrence in water, sediment and edible small indigenous fish species in seasonal freshwater wetland ecosystems of Bangladesh
Researchers found microplastics in the guts, gills, and muscle tissue of three commonly eaten fish species from seasonal wetlands in Bangladesh. Dried fish contained more microplastics than fresh fish, suggesting that the drying process concentrates plastic particles. Since these small fish are a dietary staple for local communities and are often eaten whole, this represents a direct pathway for microplastic exposure in human diets.
The Evaluation of Microplastic Reduction in Biofloc Aquaculture for Sustainable Nile Tilapia Cultivation
Researchers evaluated biofloc technology as a strategy to reduce microplastic levels in water and Nile tilapia tissues in aquaculture, using ecological risk assessment to evaluate residual contamination. Biofloc systems reduced MP concentrations in both water and fish tissues compared to conventional systems, supporting biofloc technology as a partial mitigation strategy.
Occurrence of microplastic in the water of different types of aquaculture ponds in an important lakeside freshwater aquaculture area of China
Microplastics were detected in aquaculture pond water across an important freshwater aquaculture region in China, with pond type and cultured species influencing microplastic occurrence and composition.
A comparative study of the genetically improved Abbassa Nile tilapia strain (GIANT-G9) and a commercial strain in Egypt: growth vs. stress response
This study compared a genetically improved strain of Nile tilapia with a commercial strain, focusing on growth performance and stress responses. While not about microplastics, the research is relevant to understanding how farmed fish respond to environmental stressors, since aquaculture environments increasingly contain microplastic contamination. The findings could help inform how different fish strains cope with polluted conditions in fish farming.
Microplastic pollution budget assessment of different integrated multi-trophic aquaculture (imta) systems
Researchers assessed the microplastic pollution budget of different integrated multi-trophic aquaculture (IMTA) systems, evaluating how fragmentation and degradation of synthetic construction materials including ropes, infrastructure, and pipes generate microplastic emissions within both open and recirculating aquaculture operations.
