First evidence of microplastics in Deveximentum insidiator from a potential fishing zone in the southeastern Arabian Sea.
AI summary Read the abstract
Researchers documented the first evidence of microplastics in the pony fish Deveximentum insidiator collected from a commercially important fishing zone in the southeastern Arabian Sea, characterizing particle types and polymer composition in this species valued for its nutritional content and role as fishermen's bait.
Deveximentum insidiator, commonly known as the pony fish, is a vital marine schooling species found in the shallow benthic zones of the Indo-West Pacific coastal regions. This species is commercially important, being sold both fresh and dry-salted, and is highly valued for its nutritional content, including protein, omega-3 fatty acids, vitamins, and minerals. Notably, the amphidromous nature of D. insidiator allows for remarkable adaptability to diverse environments. Due to their small size, abundance, and limited defence mechanisms, these fish are also utilized as bait by fishermen targeting larger species. Recognizing the ecological and economic significance of D. insidiator, we conducted a study on 51 individuals from a potential fishing zone in the southeastern Arabian Sea to assess microplastic (MP) pollution. Our analysis revealed a total of 1326 microplastic particles, averaging 28.21 (±17.73) MPs per individual across all examined organs. The distribution of MPs was highest in the gastrointestinal tract (31.8 Also see: https://micro2024.sciencesconf.org/559059/document

An assessment of microplastics in the ecosystem and selected commercially important fishes off Kochi, south eastern Arabian Sea, India
AI summary Read the abstract
Microplastics were found in coastal waters, sediment, and the guts of five commercially important fish species off Kochi, India, including sardines and mackerel, with polyethylene and polypropylene the dominant polymer types. The study establishes baseline contamination data for the southeastern Arabian Sea and highlights pelagic fish species as vectors of plastic pollution to human consumers.
