Concerns regarding the accumulation of microplastic in fish cages that could have an effect on human health when consumed are raised by the way farmed fish bite nylon netting. Net biting is actually caused by biofouling on the mesh, which is a tasty food that attracts fish. Therefore, it is possible that some of the microplastics from the mesh will be consumed by fish and that after people eat the fish, those microplastics will enter their digestive systems. Additionally, through marine currents, land fluxes, and feeding chains in the ocean, caged fish may come into contact with microplastics. Comparisons with natural populations of Turkish and Iranian fish have been done in order to assess the level of microplastic contamination in fish kept in cages. seas, in order to demonstrate the dangers of fish-to-human microplastic transmission. The amount of microplastics in diets has been assessed through analyses of water samples, sediments, diets, zooplankton, and fish tissues. The FT-IR spectrometer was used to identify the polymeric components in the collected microplastics, and Raman spectrometry was used to ascertain the shape, size, and polymer type of the microplastics. Based on the preliminary findings, the connection between the hazards to human health associated with consuming contaminated fish and the effect of cage nets on microplastic buildup in fish digestive systems has been evaluated. The results of this study could contribute to the development of sustainable cage aquaculture management practices that ensure future generations have access to healthy food.
