Vi nhựa và siêu vi nhựa trong hoạt động nuôi biển – tình hình ở Việt Nam

Abstract

   Microplastics in general (≤ 1,000 μm) are increasingly released into marine and coastal environments from external sources (rivers, land, atmospheric deposition, etc.) and/or from marine activities (tourism, transportation, fishing, and aquaculture). This issue has become more serious and has attracted growing concern due to their harmful impacts on organisms, environment, and entire ecosystem — including components involved in mariculture. Numerous studies have shown that microplastics can accumulate in organisms and affect physiological, biochemical, and genetic processes, thereby influencing behavior, growth, and development. These effects ultimately reduce economic efficiency and pose potential risks to consumers, particularly for crustaceans, mollusks, and marine fish — the main species of Vietnam’s mariculture sector. Similar concerns exist in Vietnam, where data indicate that coastal areas are likely affected by plastic waste in general and microplastics in particular. Therefore, following the “precautionary approach,” it is necessary to investigate the problem and develop appropriate solutions to microplastic pollution in mariculture activity.
