Black Gill Syndrome of Shrimp and Prawns
Category 4 (Negligible Regulatory Significance in Canada)
Common, generally accepted names of the organism or disease agent
Black gill disease, Burned gills, Black spot disease, Branchiostegite melanization.
Scientific name or taxonomic affiliation
Manifestation of a number of disease syndromes including ascorbic acid deficiency.
All penaeids, Macrobrachium rosenbergii, Pandalus borealis and Pandalus platyceros especially under captive/culture conditions.
Impact on the host
Destruction and dysfunction of gill processes, secondary infections.
Gross Observations: Multifocal black or brown spots in, or general discolouration of, the gills, due to melanization at sites of tissue necrosis. Gill melanization may be visible through side of carapace.
Wet Mounts: Will identify condition as above.
Histology: Massive haemocyte accumulation (called inflammation by some authors), tissue necrosis and melanin deposition in affected areas of gills. Secondary infections of bacteria, fungi and protozoa may occur.
Methods of control
May be due to a variety of biotic and abiotic agents; prevention or control may be feasible if cause can be identified.
