Abstract :
Microplastic pollution in aquaculture environment and products has spread globally and entered aquaculture environment in different ways. Microplastics can accumulate in aquaculture products. They can be transferred between trophic levels from herbivores to carnivores. Also, there is a problem of their accumulation in many pools and places for breeding aquatic animals. This research aimed to investigate the impact of microplastics on aquaculture industry and the health of the environment and humans. The sources of microplastics in aquaculture can be microplastics imported from the external environment (including river, sea, land, atmosphere) and during the process of aquaculture (including aging and wear of plastic fishing equipment, feeding, and packaging of products Aquaculture) was divided. Among the river microplastic sources, we can mention industrial effluents, human activities, sewage treatment plants, agricultural activities, etc. Also, among industrial, textile wastewater was the main source of fibrous microplastics in rivers. Due to long-term immersion, erosion, wear and impact, nets, fishing lines, floating balls, and other plastic products used for cage and boat culture can produce microplastics and enter the aquaculture environment. These polymer pollutants have toxic effects on the microalgae in the water, which can affect the ecological balance of the aquaculture environment. Some studies have shown that microplastics with maximum diameter of 130-micrometers can penetrate blood vessels and lymph nodes of mammals and transported to different parts of body through blood and lymph circulation. Therefore, due to the impact of microplastics on aquaculture industry, human health, and environment, this issue requires serious attention.
