Black gill disease

Black gill disease is a disease of crustaceans.

Occurrence[edit | edit source]

It has been observed in spiny lobsters (Panulirus ornatus) in Vietnam,^[1] where it is caused by a species of Fusarium.^[1]

It has been observed in shrimp, where the agent is microscopic protozoan Hyalophysa chattoni or a close relative, in Galveston Bay, Texas and other locations.^[2]

Causes[edit | edit source]

There are multiple sources known to cause black gill disease. Poor pond conditions can cause debris to build up in the gills turning them black. Certain kinds of bacteria and the fungus genus Fusarium are also known causes.^{[citation needed]}

Prevention[edit | edit source]

With extra care taken to the health of the shrimp, it is possible to prevent cases of black gill disease. The water should have 10-20 parts per thousand parts salinity and filtered.^[3]
