Anthelmintic efficacy of febantel against a monogenean parasite, Gyrodactylus kobayashii.

Monogenean parasites pose a significant challenge to aquaculture, leading to adverse effects on fish health and yields. Current anthelmintic treatments for monogeneans have demonstrated limited efficacy and are further complicated by potential issues, which emphasize the necessity for effective and safe therapeutic strategies to manage monogeneans in aquaculture. In this study, in vivo and in vitro anthelmintic activity of febantel against Gyrodactylus kobayashii on goldfish (Carassius auratus), as well as its toxicity to goldfish were evaluated.

A modified withdrawal time estimation and risk assessment of enrofloxacin in grass carp (Ctenopharyngodon idella) after ad libitum medicated feed based on statistical approaches in natural cultured environments.
