Summary: This study revealed that environmentally relevant concentrations of IBU significantly impacted the haematology and organ histology of Clarias gariepinus, inducing alterations in blood indices and histopathological deformities in the gills, liver, and kidney. These findings can provide baseline information for regulatory agencies in setting safe limits for NSAIDs to safeguard the aquatic environment.

Summary: The study investigated the effects of tramadol on C. gariepinus juveniles, finding that exposure led to abnormal behavior, increased mortality, changes in hematological parameters and oxidative stress responses. The results suggest that tramadol is toxic to fish and its use in aquatic environments should be monitored.

Summary: Pharmaceutical compounds, along with pesticides, heavy metals, and personal care products, are emerging contaminants that pose a major concern for aquatic ecosystems. The presence of pharmaceuticals can affect both freshwater organisms and human health through non-target effects and contamination of drinking water sources. This study explored the molecular and phenotypic alterations of commonly found pharmaceuticals in aquatic environments in daphnids, finding changes in enzyme activities and metabolic perturbations. Chronic exposure to low concentrations of pharmaceuticals resulted in significant alterations in metabolic and physiological endpoints.

Summary: Fingerlings and juveniles of African catfish were reared under experimental conditions and exposed to different concentrations of Fe-DTPA. Various factors such as growth, behavior, immune response, histopathological changes, and genetic biomarkers were evaluated. The results indicate that Fe-DTPA supplementation at the tested concentrations is relatively harmless for the health and welfare of African catfish.

Summary: Petroleum exploration in the Niger Delta region of Nigeria has led to contamination and destruction of the ecosystem, resulting in increased levels of oxidative stress markers and alterations in antioxidant status in fish organs. The frequency of micronucleated polychromatic erythrocytes was significantly higher in fish samples from polluted rivers compared to the control, indicating pollution mainly by oil spillage and industrial activities in these rivers.

Summary: The study found that exposure to silver nanoparticles induced various behavioral and physiological responses in African catfish, including surfacing for gasping air, restlessness, and slow swimming. Hematological indices, neurotransmitter activity, and oxidative stress parameters showed significant reductions in fish exposed to silver nanoparticles, whereas stress indicators decreased.

Summary: This study aimed to optimize the induction of tetraploid in African catfish eggs using cold shock protocol. The best results were achieved with 5 degrees C cold shock for 2 or 5 minutes. Tetraploid progenies had longer erythrocyte axis length compared to diploid counterparts, but were similar in terms of morphological characterization and growth performance.

Summary: This study aimed to estimate the methionine requirement of African Catfish and found that growth rate, feed conversion ratio, and other parameters were significantly affected by dietary methionine levels. The research suggested a lower digestible methionine requirement for growth in African catfish compared to previous reports.

Summary: This study reports the presence of pyrogallol in wastewater in Egypt for the first time. Acute and sub-acute toxicity experiments were conducted to evaluate the toxic effects of pyrogallol on catfish. The results showed that pyrogallol exposure caused morphological changes, hematological and biochemical alterations, indicating potential risks to aquatic species.
