Mackerel (Rastrelliger sp) is a type of epipelagic fish that has habitat in coastal and marine areas. The eating habit of mackerel is to eat large or coarse plankton, copepods and crustaceans, where the prey of these fish can live in waters that have been contaminated with microplastics so that these microplastics accumulate in the digestive tract of mackerel. This study aims to identify the type, color, and size of microplastics found in samples of mackerel (Rastrelliger sp) caught in the waters of Lampulo, Aceh Province. Data collection was carried out in January-July 2022. The data in this study were taken using a survey method with random sampling technique. The object of this research is mackerel (Rastrelliger sp) caught in Lampulo Waters, Aceh Province. The research parameters were the type, color, and size of microplastics found in the digestive tract of mackerel (Rastrelliger sp). Data analysis was carried out descriptively, displayed in the form of pictures, tables, and graphs based on the type, color, and size of microplastics. Based on the results of the study, it was found that 1) There were 4 types of microplastics found in the digestive tract of mackerel; 2) The color of microplastics found in the digestive tract of mackerel was found in 4 colors; 3) The size of microplastics found in the digestive tract of mackerel ranges from 0.6-54.7 m. It was concluded that in the digestive tract of mackerel caught in Lampulo waters, Aceh Province, it was proven to contain microplastics, 4 types of microplastics were found, namely fiber, fragment, film, and pellet types, 4 colors of microplastic were found, namely black, red, yellow, and transparent, The size of the microplastics found ranged from 0.6-54.7 m.
