Bath Treatments With Emamectin Benzoate Control Dactylogyrideans Infecting Colossoma macropomum Gills Without Altering Physiology of This Host Fish

Journal of Fish Diseases, EarlyView.
ABSTRACT Intensification of fish aquaculture worldwide has led to severe problems of diseases caused by parasitic dactylogyrideans. In this study, the anti‐dactylogyridean efficacy of treating Colossoma macropomum with baths of emamectin benzoate (EMB) was investigated for the first time, along with the effects of this treatment on the haematology and ...

Rapid Clearance of Tetracapsuloides bryosalmonae Spores by Freshwater Sponge Ephydatia muelleri: Potential Implications for Controlling Proliferative Kidney Disease in Salmonids

Journal of Fish Diseases, EarlyView.
ABSTRACT Host–parasite interactions are influenced by both abiotic and biotic factors. While abiotic drivers, particularly temperature, have received considerable attention in recent years due to global climate change, the role of biotic factors remains comparatively underexplored.

Effects of Kudoa thyrsites on Proximate Composition and Texture of Merluccius capensis and Zues capensis

Journal of Fish Diseases, EarlyView.
ABSTRACT Kudoa thyrsites is a myxosporean endoparasite that infects fish, frequently resulting in myoliquefaction, impacting the texture and eating quality of fish muscle. The aim of this study was to investigate the effects of K. thyrsites infection on the proximate composition and texture parameters of raw fillets from two South African economically ...
