These enzymes break down cells and tissues enabling the fungi to absorb nutrients such as proteins and carbohydrates. This isn’t a problem if it's a piece of fish food – but it’s not so welcome when it is one of your fish that is being slowly digested.
Branchiomyces in carp gills is usually localized in the blood vessels, the efferent branchial vessels and the capillaries, producing branched coenocytic hyphae capable of producing aplanospores by endogenous cleavage. In eels branchiomycosis hyphae and spores spread to visceral organs. Infection is...(for more details - click on product image)
One of the most common fungal infections of Koi. The fungal spores will grow anywhere on the Koi, including the gills, initially germinating on dead tissue. Their threadlike hyphae release digestive juices which break down the tissue so the fungus can absorb it, as the fungus grows these juices start...(for more details - click on product image)
