Survival rate and growth performance of tilapia (Oreochromis niloticus) exposed in polyvinyl chloride microplastics
Summary
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.
Plastic is one of the materials most widely used by humans. The more plastic that is used, the more plastic waste is released into environment and will polute water areas in various sizes, both macroplastics and microplastics. Microplastic are classified as plastic particles whose diameter is less than 5 millimeters. One type of microplastic that has an adverse impact on the life of aquatic organisms is polyvinyl chloride (PVC). The aim of this research was to determine the effect of PVC microplastic exposure on the survival rate and growth performance of tilapia, Oreochromis niloticus. This study was conducted in a completely randomized design (CRD) consisting of four treatments with three replications. The treatments were as follows: MP0 = No addition of microplastics (control); MP1 = Addition of 5 mg/L microplastics; MP2 = Addition of 15 mg/L microplastics; MP3 = Addition of 20 mg/L microplastics. The results showed that exposure to polyvinyl chloride microplastics on the survival rate and growth performance of tilapia through water made a real difference to Survival Rate (SR), absolute weight growth, absolute length growth, Specific Growth Rate (SGR), Feed Convension Ratio (FCR) and the abundance of polyvinyl chloride microplastics in fish gut.Keywords:MicroplasticPolyvinyl chlorideTilapiaSurvival rateGrowth performance

The The Effect of Exposure to Microplastic Polyvinyl Chloride (PVC) in Feed on the Growth and Survival of Tilapia (Oreochromis niloticus)
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.
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.
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.
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.
