Several factors can contribute to the onset of swim bladder disease. Overfeeding is a common cause, leading to constipation which may press against the swim bladder. Bacterial or viral infections affecting the swim bladder can also trigger this condition. [76] Physical injury or congenital deformities of the swim bladder are other potential causes.
Viral hemorrhagic septicemia. Viral hemorrhagic septicemia (VHS) is a deadly infectious fish disease caused by Viral hemorrhagic septicemia virus. It afflicts over 50 species of freshwater and marine fish in several parts of the Northern Hemisphere. [1] Different strains of the virus occur in different regions, and affect different species.
