In this study, we describe the complete mitochondrial genomes of Gyrodactylus brachymystacis and Gyrodactylus parvae infecting rainbow trout ( Oncorhynchus mykiss ) and the invasive topmouth gudgeon ( Pseudorasbora parva ), respectively. The two circular genomes have a common genome organization found in other Gyrodactylus species. Comparative analyses of mitochondrial genomes from six Gyrodactylus species were carried out to...

The previously unreported presence of transferrin in Atlantic cod Gadus morhua epidermal mucus is described. A less destructive sampling method, which may result in decreased epidermal tissue damage, is discussed.

This study examined changes in Atlantic salmon Salmo salar epidermal mucus proteins following short‐ and long‐term handling stress. Short‐term stress consisted of a single removal of fish from water for 15 s with long‐term stress consisting of daily removal of fish from water for 15 s over 21 days. In the long‐term handling stress study, there was a high level of individual variability with respect to mucus alkaline phosphatas...
