White leg shrimp, Litopenaeus vannamei (Boone,
1931) is considered as a species that revolutonized
shrimp farming industry in India in the recent past.
There has been a marked shift from farming of
indigenous black tiger shrimp, Penaeus monodon to
culture of exotic white leg shrimp, L. vannamei in
India from the beginning of this century. With its
present performance in Asia, world production of
this species will overtake all other cultivated shrimp
species. Over 90% of shrimp culture in Western
hemisphere is represented by white shrimp
(Wurmann et al., 2004). Intensification of shrimp farming poses several
problems including the sporadic occurrence of
diseases in farms. In addition to the most widely
occurring viral and bacterial diseases a number of
less prevalent disease manifestations are also observed
in shrimp farming sector. The present study
deals with the observation of black discolouration
of gills of farmed L. vannamei and its mitigation
using a pond sanitizer. Black gill syndrome is also
known as black gill disease, burned gills, black spot
disease, and branchiostegite melanization. Generally
there are multifocal black or brown spots in gills,
or general discoloration of gills due to melanization
at the sites of tissue necrosis.
