Fungus disease, Fusariosis, Black gill disease (in Penaeus japonicus).

Scientific name or taxonomic affiliation

Fusarium solani, Fusarium moniliforme and possibly other Fusarium spp. The phycomycetous fungi Atkinsiella dubia and Haliphthoros spp. are rare pathogens of penaeids but they have been associated with gill and cuticular lesions somewhat similar to those caused by Fusarium.

Geographic distribution


Host species

All penaeids and Macobrachium rosenbergii at all stages of development. Also observed in small Pandalus platyceros juveniles under experimental culture conditions. Other marine crustaceans such as lobsters held in culture facilities can also become infected.

Impact on the host

Fusarium infects dead or damaged tissue caused by wounds or other infections resulting in locomotory difficulties due to mycelial growth. High mortality in susceptible populations. Fouling of the gills by these organisms probably results from poor husbandry.

Diagnostic techniques

Wet Mounts: Material from lesions contain canoe-shaped macronidia.

Methods of Control

Because these fungi tend to be opportunistic pathogens capable of establishing infection only in shrimp compromized by other infectious agents, exposure to chemical irritants or heavy metals, excessive overcrowding, or poor environmental conditions, disease may be circumvented by adequate husbandry.
