The The Effect of Exposure to Microplastic Polyvinyl Chloride (PVC) in Feed on the Growth and Survival of Tilapia (Oreochromis niloticus)
Summary
Researchers studied the effects of polyvinyl chloride microplastics mixed into feed on the growth and survival of tilapia fish over a 30-day period. They found that higher concentrations of microplastics in feed led to reduced growth rates and lower survival compared to the control group. The study suggests that microplastic contamination in aquatic environments could negatively affect commercially important fish species through dietary exposure.
The presence of microplastics in the waters is due to plastic garbage that is difficult to decompose. Tilapia that live in the water has a high tolerance for polluted environments, thus making them vulnerable to microplastic contamination. The most common type of microplastic found in water is polyvinyl chloride. The study aims to investigate the effects of microplastic exposure on Tilapia growth and survival. The research plan used a complete random design (CRD) with four treatments and three repetitions. Exposure to microplastics in fish is carried out through feeding, with doses: without microplastic addition; addition of 0.01 mg per 0.75 g of feed; addition of 0.1 mg for 0.75 g of feeding; and addition of 1 mg for every 0.75 grams of feed. The mixed microplastic feed was given three times a day at a dose of 5% of the fish's body weight. Growth and survival data are analyzed using Anova; if there is any real impact, then further testing is done using Duncan. The study's findings showed that adding microplastics to specific weight growth, absolute weight, absolute length, feed conversion ratio, and survival at a dose of 1 mg per 0.75 g of feed was significantly different from treating the animals without adding microplastics. Therefore, we can conclude that a dose of 1 mg per 0.75 g of feed will impact the growth and survival of tilapia.

Survival rate and growth performance of tilapia (Oreochromis niloticus) exposed in polyvinyl chloride microplastics
This study tested how polyvinyl chloride (PVC) microplastics affect the survival and growth of tilapia, a widely eaten fish. While focused on fish rather than humans, it provides data on how microplastics in water can harm aquatic life that ends up on our plates. The findings add to concerns about microplastic contamination in the food chain.
Ingestion and the toxicological effects of virgin polyethylene (PE) and polyvinylchloride (PVC) microplastics in commercial freshwater fish, tilapia (Oreochromis niloticus)
Researchers exposed tilapia to polyethylene and polyvinyl chloride microplastics through their diet over 21 days and observed behavioral changes, mortality, and reduced growth rates. The study suggests that ingestion of common microplastic types can impair the health and survival of commercially important freshwater fish, with implications for aquaculture and food safety.
The Effect of Polyvinyl Chloride (PVC) Microplastic Exposure in Feed on The Growth Performance and Survival of Catin Fish (Pangasius hypophthalmus)
This study tested how PVC microplastics in feed affect the growth and survival of catfish. It found that microplastic exposure reduced fish growth performance, demonstrating how plastic contamination in aquatic environments can impact the food chain and potentially the seafood people eat.
Ingestion and the toxicological effects of virgin polyethylene (PE) and PVC microplastics in commercial freshwater fish, Tilapia (Oreochromis niloticus)
Researchers exposed Nile tilapia to virgin polyethylene and PVC microplastics for 21 days, finding that both types caused behavioral changes and mortality, with PVC producing greater toxicity, reduced growth rates, and histological damage to gut and liver tissue.
Assessment of dietary polyvinylchloride, polypropylene and polyethylene terephthalate exposure in Nile tilapia, Oreochromis niloticus: Bioaccumulation, and effects on behaviour, growth, hematology and histology
Nile tilapia fish fed three common types of microplastics (PVC, polypropylene, and PET) showed reduced growth, abnormal behavior, blood cell damage, and tissue damage in their gills, liver, and intestines. The harmful effects increased with higher doses of microplastics and varied by plastic type. Since tilapia is one of the most widely consumed fish globally, these findings raise concerns about the health of fish that may carry microplastic contamination to human diets.
