Microplastics contamination in commercial marine fish from the Bay of Bengal

This study investigated the abundance and characteristics of microplastics in commercial fish species from the Bay of Bengal, off the coast of Bangladesh. The gastrointestinal tracts of 100 individuals from 10 species of commercial marine fish were examined for microplastics. Microplastics were detected in all species. A total of 215 microplastics were recovered with an average abundance in the range of 2.2 ± 0.89 microplastics per individual. Five types of microplastics were found: fibers, films, fragments, foams, and granules, which accounted for 53.4%, 40%, 3.3%, 1.9%, and 1.4% of the total, respectively. Among the identified microplastics, green (39%) was the most dominant color, and
