Retraction Note: An assessment of physiological and health responses in Catla catla fingerlings after polystyrene microplastic exposure
AI summary Read the abstract
This is a retraction notice for a study on polystyrene microplastic exposure in Catla catla fish, withdrawn after data irregularities were identified, including figures that appeared to be reused from other papers representing different conditions or species. The retraction underscores the importance of data integrity in microplastics research, where replication and accuracy are critical.
After publication, concerns were raised regarding data irregularities.Specifically, Figure 7 in the paper appears to partially overlap with Figure 4 in 1 , where it represents a different condition, and Figure 5 in 2 , where it represents a different species.Concerns were also raised regarding the error bars displayed in Figure 6.

RETRACTED ARTICLE: An assessment of physiological and health responses in Catla catla fingerlings after polystyrene microplastic exposure
AI summary Read the abstract
Note: This article has been retracted. The study reported that feeding polystyrene microplastics to Catla catla fish reduced growth, impaired blood health, decreased nutritional quality, and caused intestinal damage. Higher concentrations of microplastics led to worse outcomes across all measures. While the retraction means these specific results should be viewed with caution, the general concern about microplastic effects on farmed fish remains supported by other research.
RETRACTED: Assessment of polystyrene microplastics as dietary additives in aquaculture species, Catla catla: Alters growth, feed utilization, nutritional composition, hematology and gut histopathology
AI summary Read the abstract
Note: This paper has been retracted. It reported that feeding polystyrene microplastics to a freshwater fish species reduced growth, nutritional quality, and caused gut damage in a dose-dependent manner. While the specific findings should be treated with caution due to the retraction, the general concern about microplastics accumulating in aquaculture fish and affecting their nutritional value and safety for human consumption remains supported by other research.
Paper on microplastics in fish is retracted
AI summary Read the abstract
This news article reported on the retraction of a high-profile Science paper claiming that polystyrene microplastics from personal care products could inhibit hatching, stunt growth, and increase predation in perch, after investigators raised concerns about missing data and irregularities in how the study was conducted. The retraction serves as a cautionary case study for the importance of rigorous methodology and data transparency in microplastic toxicology research.
RETRACTED: Environmentally relevant concentrations of microplastic particles influence larval fish ecology
AI summary Read the abstract
Note: This paper has been retracted by the journal. The original study claimed that microplastic exposure at environmental levels harmed larval fish development and behavior, but the findings were later deemed unreliable. Retracted studies should not be used as evidence for microplastic health effects, though the topic of microplastic impacts on early-life fish development continues to be studied by other research groups.
