This study focuses, for the first time, on the presence of plastic debris in the stomach contents of large pelagic fish (Xiphias gladius, Thunnus thynnus and Thunnus alalunga) caught in the Mediterranean Sea between 2012 and 2013. Results highlighted the ingestion of plastics in the 18.2% of samples. The plastics ingested were microplastics (<5 mm), mesoplastics (5-25 mm) and macroplastics (>25 mm). These preliminary results represent an important initial phase in exploring two main ecotoxicological aspects: (a) the assessment of the presence and impact of plastic debris on these large pelagic fish, and (b) the potential effects related to the transfer of contaminants on human health.
Microplastics in Pelagic and Demersal Fishes of Pantai Baron, Yogyakarta, Indonesia
Jurnal Biodjati
Yogyakarta is the second-largest producer of plastic waste in Indonesia. Plastic waste in the waters can be degraded into microplastics that can enter the body of a fish. This study aimed to determine the presence of microplastics in the digestive tract of several species of fish in Pantai Baron, Yogyakarta, Indonesia. This research was an exploratory research conducted in April-September 2019 at Pantai Baron, Yogyakarta. Two species of each pelagic and demersal fish samples were taken by buying fish caught by fishermen. The digestive tract of fish was extracted with 10% KOH, filtered, then visual identification. Microplastic types were estimated by FT-IR spectrometry. The amount of microplastic of all fishes was done by Kruskal-Wallis test while the number of microplastics of the two categories of fish was compared with the Mann-Whitney test. A correlation analysis was carried out between the length of the fish, the weight of the digestive tract, and the number of microplastics fou...

The ubiquity of anthropogenic debris in hundreds of species of wildlife and the toxicity of chemicals associated with it has begun to raise concerns regarding the presence of anthropogenic debris in seafood. We assessed the presence of anthropogenic debris in fishes and shellfish on sale for human consumption. We sampled from markets in Makassar, Indonesia, and from California, USA. All fish and shellfish were identified to species where possible. Anthropogenic debris was extracted from the digestive tracts of fish and whole shellfish using a 10% KOH solution and quantified under a dissecting microscope. In Indonesia, anthropogenic debris was found in 28% of individual fish and in 55% of all species. Similarly, in the USA, anthropogenic debris was found in 25% of individual fish and in 67% of all species. Anthropogenic debris was also found in 33% of individual shellfish sampled. All of the anthropogenic debris recovered from fish in Indonesia was plastic, whereas anthropogenic debr...

Every year, it is estimated that the Indonesian seas receive 100,000-400,000 tons of plastic waste used for human consumption. Indiscriminate disposal of plastic waste will have an impact in the future. The problem of microplastics is an illustration that the use of plastic in daily activities will cause environmental ecological damage. The purpose of the study was to describe microplastic contamination in marine fish and shells in the coastal areas of Jember Regency, Indonesia. The method used is to detect and identify the type and numbers of microplastic particles in the gastrointestinal tract content of sea fish and shells obtained from fishermen around Payangan and Puger coastal Jember, Indonesia. The gastrointestinal tract was extracted with peroxide oxidation method (WPO). A light microscope was used to examine microplastic particles of types and numbers. The results showed that marine fish and shells in the coastal area of Jember Regency, Indonesia have been contaminated with microplastic. The microplastic in each marine fish and shells sample has a different type. There were microplastic types of fiber, fragments, granules, and filaments in the shells sample, while in the marine fish samples, there were all these types except granules. Fish and shellfish on the coast of Payangan and Puger had several types of microplastics detected in their gastrointestinal tract.
Ingestion of plastic by fish destined for human consumption in remote South Pacific Islands
Plastic marine debris is increasingly recognised as one of the greatest threats to global oceans, and the humans who depend on them. This study documents plastic ingestion in 24 species caught or sold for human consumption in the South Pacific. Fish were collected from local fishermen and markets in remote locations, including French Polynesia, Lord Howe Island and Henderson Island (Pitcairn group). Gastrointestinal tracts of 126 fish were visually examined and plastic was found in 7.9% of individual fish and 25% of species. The plastics were mostly microplastics (fragments, nurdles and rope). There was no significant difference in plastic ingestion in relation to feeding style, length, region or species. This is concerning as plastic appears to be widespread across species, lifestyles and habitats. This is the first report of plastic in South Pacific fish, raising concerns about the transfer of pollutants in a region that is largely oceanic and heavily dependent on seafood. The remote locations of the study also provide evidence of the widespread nature of this issue.
Plastic debris and fibers from textiles in fish and bivalves sold for human consumption
2015
The ubiquity of anthropogenic debris in hundreds of species of wildlife and the toxicity of chemicals associated with it has begun to raise concerns regarding the presence of anthropogenic debris in seafood. We assessed the presence of anthropogenic debris in fishes and shellfish on sale for human consumption. We sampled from markets in Makassar, Indonesia, and from California, USA. All fish and shellfish were identified to species where possible. Anthropogenic debris was extracted from the digestive tracts of fish and whole shellfish using a 10% KOH solution and quantified under a dissecting microscope. In Indonesia, anthropogenic debris was found in 28% of individual fish and in 55% of all species. Similarly, in the USA, anthropogenic debris was found in 25% of individual fish and in 67% of all species. Anthropogenic debris was also found in 33% of individual shellfish sampled. All of the anthropogenic debris recovered from fish in Indonesia was plastic, whereas anthropogenic debris recovered from fish in the USA was primarily fibers. Variations in debris types likely reflect different sources and waste management strategies between countries. We report some of the first findings of plastic debris in fishes directly sold for human consumption raising concerns regarding human health. The ubiquity of anthropogenic marine debris and the toxicity of chemicals associated with the material have begun to raise concerns regarding how the ingestion of anthropogenic debris by marine animals may impact human health 1. These concerns have prompted a concerted effort from government and private organizations to assess the impacts of marine debris on human and environmental health, including organizations such as NCEAS (National Center for Ecological Analysis and Synthesis), UNEP (United National Environment Programme), US EPA (United States Environmental Protection Agency), GESAMP (Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection) and NOAA (National Oceanic and Atmospheric Administration). Almost every report from these groups concluded further research is required to elucidate how marine debris may be affecting humans, and thus, whether inadequate waste management strategies are coming back to haunt us in our seafood. Due to the large presence of anthropogenic marine debris in aquatic habitats 2-5 and wildlife 6-8 , we hypothesized that anthropogenic debris would be present in marine animals sold for human consumption. Anthropogenic marine debris is seemingly found across all habitats in the ocean, including coral reefs 9 , shallow bays 10,11 , estuaries 12 , the open ocean 13,14 and the deep sea 15,16.

Microplastics Ingestion by Fish in The Pangandaran Bay, Indonesia
2019
This study investigated the occurrence of microplastic particles in the digestive tracts of fishes from Pangandaran bay. The fish were collected by local fisherman. A total of 18 fish representing 2 species (Trichiurus sp. and Johnius sp.) were examined for microplastics. In total, 193 microplastic particles were found in the gastrointestinal tracts of all fishes. Microplastic particles were categorized as fragment (49.74%), fiber (22.8%) and film (27.46%), with size ranging from 0.12 to 5 mm. A statistically significant difference existed in the abundance of microplastic ingestion among the two species. The results of this study provide the first evidence of microplastic contamination in fish in Pangandaran bay.

Microplastics (MPs) have infected fish, crustaceans, and mollusks, among other marine fisheries products. This investigation was to determine the microplastic content of the gills, musscle, and intestines of Grouper (Genus epinephelus) in Pasar Bengkulu, Indonesia. This study was conducted in July-August 2022 with a random sample of 25 participants. At the Laboratory of Fisheries Marine Science Univerisity of Bengkulu, microplastics were analyzed. In the gills, musscle, and intestinal of Grouper Fish (Genus epinephelus), researchers discovered three types of microplastics, including fiber, film, and fragments, with a total abundance of 3.60 particles per individual. Transparent, black, and yellow were the hues discovered. Black predominated the color palette of the microplastic. 40.32μm - 675.31μm was the range of microplastic size. The FTIR analysis identifies the polymer as Polyethylenimine, Epichlorohydrin-Modified, 17 Wt% Solution In Water.
Characterization of microplastic in trawl fish caught in Padang City (Indonesia) coastal area
Biodiversitas, 2023
Marine organisms can ingest microplastics that are distributed in the oceans. It can harm marine organisms because carcinogenic materials easily attach to microplastics. Trawl fish is a commercial fish with a high demand from people in Padang City, West Sumatera, Indonesia. This study aimed to analyze the abundance of microplastics in the gastrointestinal tract of fish. Also, analyze the microplastic characteristics in trawl fish caught on Pasir Jambak Coast and Purus Coast in Padang City. The species studied were Sulphur goatfish (Upeneus sulphureus), Indian mackerel (Rastrelliger kanagurta), and White sardinella (Sardinella albella). Microplastics were identified using microscopy and FTIR spectroscopy. Microplastic abundance in Sulphur goatfish, Indian mackerel, and White sardinella was 3.89±1.36 per fish, 4.22±1.28 particles per fish, and 2.50±0.46 particles per fish, respectively. The size of the most commonly found microplastics ranged from 1-5 mm and was categorized as the Large Microplastic (LMP) type. Fourier Transform Infra-Red (FTIR) spectroscopy analysis showed that the origin of the type of microplastic polymer found was Polyethylene Terephthalate (PET). Statistically, it shows that the difference in the location and time of sampling does not provide a significant difference in the concentration of microplastics in fish and seawater. The results of this study indicated that microplastics were found in the waters and all fish samples on the coast of Padang City studied. Microplastics in the trawl fish can be used to manage plastic waste in the city to prevent a worse impact due to plastic pollution in the future.
