Microplastic Abundance and Characteristics in Rabbitfish Siganus guttatus and Parrotfish Scarus ghobban from the Local Market of Zamboanga City, Philippines
AI summary Read the abstract
This Philippine study found microplastics in the digestive tracts of rabbitfish and parrotfish sold in public markets in Zamboanga City. Both reef fish species showed microplastic contamination, highlighting food safety concerns for consumers who regularly eat these locally caught fish.
Microplastic pollution is a global problem. In a particular area of concern, Rabbitfish and Parrotfish are good bioindicators of microplastic pollution because they have high site fidelity. This study aimed to investigate the MPs contamination in Rabbitfish Siganus guttatus and Parrotfish Scarus ghobban sold in the local public market of Zamboanga City, Philippines. Thirty-five (35) samples of each fish bought from the local Magay public market, Zamboanga City, were subjected to MP’s laboratory analysis. The study revealed that all fish samples had MPs in their guts. Rabbitfish have greater MPs at 51.97 per sample than Parrotfish at 19.29 per sample. Regression analysis showed a significant negative relationship between the weight and length of Rabbitfish and the MPs abundance but no significant difference in Parrotfish; most of the MPs ingested by both species can be attributed to the area where they are caught. Blue filaments are the most present in Rabbitfish, while red filaments are most present in Parrotfish. These filaments are from terrestrial sources, mainly from textiles washed into the oceans via rivers and sewers from households.

Microplastic Occurrence in the Gastrointestinal Tract of Rabbitfish (Siganus canaliculatus) in Pujada Bay, Philippines
AI summary Read the abstract
Researchers evaluated microplastic ingestion in rabbitfish (Siganus canaliculatus) from Pujada Bay, Philippines, finding MPs in the gastrointestinal tracts of 27.5% of 80 individuals with FTIR spectroscopy confirming the polymer types present. The study documents MP contamination in a commercially important reef fish species, raising concerns about trophic transfer and seafood safety in Philippine coastal waters.
Occurrence and Visual Characteristics of Suspected Microplastics in the Gastrointestinal Tract of Wild Rabbitfish (Siganus guttatus) from Tamisan, Pujada Bay, Philippines
AI summary Read the abstract
Scientists found tiny plastic fibers, mostly blue, in the guts of about 1 in 4 wild rabbitfish caught in a Philippine bay — a popular fish for local diets. While this study didn't test whether these fibers make it into the parts of the fish people actually eat, it's a reminder that plastic pollution is working its way into seafood, adding to the case for reducing plastic waste that ends up in our oceans.

AI summary Read the abstract
Researchers sampled fish sold at four traditional markets in Palu City, Indonesia, and found microplastics in the digestive systems of two commonly eaten species: mackerel (Rastrelliger kanagurta) contained plastic flakes, while rabbitfish (Siganus canaliculatus) contained both flakes and fibers at higher concentrations. Because these fish are widely consumed locally, the findings raise direct concerns about human dietary exposure to microplastics through seafood.
