Microplastic study on (litopenaeus vannamei) cultivation enterprises on the east coast of aceh
Summary
Researchers sampled vannamei shrimp (Litopenaeus vannamei) from three cultivation stations on Aceh's east coast (Pidie, Pidie Jaya, and Bireuen) and analyzed microplastic content using H2O2/H2SO4 digestion and microscopy at 40x magnification. They found fiber and film microplastics in all shrimp samples, with the highest count (13 particles) at the Pidie station, indicating microplastic contamination has entered commercial aquaculture supply chains.
Microplastics are small plastics measuring <5mm which, if they enter the water, can contaminate aquatic biota such as shrimp. The research aims to identify the number, shape and color of microplastics in shrimp bodies in vanname shrimp cultivation businesses on the East Coast of Aceh. Shrimp samples were taken from 3 stations, namely Pidie, Pidie Jaya and Bireuen. The samples were measured for weight and length, then prepared using H 2 O 2 and H 2 SO 4 in a ratio of 3:1 20 mL then incubated, heated, then filtered and identified using a Zeiss microscope with 40x magnification. The results obtained from shrimp body samples contained 2 types of microplastics, namely fiber and film. The most dominant microplastics at the three stations were 13 particles in the Pidie location, 9 particles in the Pidie Jaya location and 5 microplastic particles in the Bireuen location. The presence of microplastics that have entered the body of biota in the vannamei shrimp cultivation business is an early warning. So it is necessary to develop research on other consumption biota to determine the presence of microplastics and their impact if consumed by the public.
