Summary: The study demonstrated that feeding African catfish males with 200 mg Ge/kg diet significantly improved growth performance, sperm quality, antioxidant capacity, and other reproductive parameters compared to other treatments. This suggests that dietary Ge at a level of 200 mg/kg has the potential to enhance reproductive success in adult African catfish males and contribute to the sustainability of aquaculture for this species.

Summary: This study investigated the effects of the antipsychotic drug haloperidol on juvenile Clarias gariepinus. It found that exposure to the drug led to changes in hematological and biochemical parameters in the fish, including reduced red blood cell count and increased neutrophil count. However, these effects dissipated after 5 days of drug withdrawal.

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: Aquaculture of the African catfish Clarias gariepinus has experienced rapid growth in recent years in Africa, Asia and Europe. This study analyzed the growth data of African catfish juveniles reared in an indoor freshwater recirculation aquaculture system and found that the Gompertz model consistently best described the growth of the species. Significant differences were also observed for one of the experimental feeds in terms of growth rate and biomass production.

Summary: Various studies have shown that using insect meal in aquaculture can reduce land use, but it also leads to greater energy consumption and larger carbon footprint compared to traditional protein sources. Substituting different types of insect meals in aquatic diets can significantly impact solid waste production, with a reduction in marine forage fish required per unit fish yield. Therefore, there is a trade-off when considering the environmental consequences of using insect meal as an aquafeed ingredient.

Summary: The invasive round goby and native European bullhead showed similarities in space use, velocity preferences, shelter use, and activity patterns, indicating high adaptability. However, a primary difference was observed in stress-induced behavior during the initial phases of observation. Despite both species being able to cope with velocities > 0.7 m s(-1), the invasion success of round goby is likely driven by higher adaptability rather than space use or activity patterns.

Summary: This study revealed that photoperiod duration significantly affects the growth rate and antioxidant capacity of largemouth bass. The 8L:16D group showed the best performance in terms of growth, organosomatic index, and antioxidant capacity. Longer light duration led to oxidative stress in fish liver, brain, and gill, but also boosted antioxidant responses in liver, brain, and kidney.

Summary: Invasive fish pose a threat to the ecological status and ecosystem services of ponds, making it crucial to accurately assess the composition of fish communities. This study compared three different sampling methods - electrofishing, fish-trapping, and throw-netting - to estimate the size distribution, density, and biomass of the invasive fish species, Pseudorasbora parva. The results showed that all three methods successfully detected P. parva, but there were significant differences in population characteristics estimates among the methods. Fish-trapping was found to be the most reliable and cost-effective method for estimating P. parva population characteristics in ponds, despite requiring more time for sampling. The study emphasizes the importance of selecting appropriate sampling gear for monitoring invasive fish in ponds.
