Studies on the fishery and biology of 'ridge-back shrimp' Solenocera choprai Nataraj occurring off Maharashtra coast
1994
Penaeid prawns belonging to the genus Solenocera have been reported to have fishery value
only off Northwest coast of India. The species exploited from the shallower regions of the coast
has been identified as Solemera crassicornis H. Milne Edwards, caught mainly in bag nets (Dol
and Bhokshi).
Another species S. choprai Nataraj was recently reported to have considerable fishery value
along Maharashtra coast, landed exclusively by mechanised trawlers, operating at 40-70 m 'depth
zone. This was found to contribute about 5% of the total penaeid catches from the region. The
fishing ground lies off Murud-Harnai coast.
S. choprai has'been recorded only from the Northwest coasts of India. This species bears a
very close resemblance to S. alticarinata Kubo. The salient features that help in its identity, along
with notes on its fishery and biology are presented, covering a period of ten years from 1977-1986.
The fishery for S. choprai was found to be highly seasonal from March to June for most of the
years, sometimes extending upto September. The observations were carried out at Sassoon dock, an
important landing centre for penaeid prawns in the state of Maharashtra. An export potential exists
for this species as it grows to a fairly large size. It is comparable in size to S. crassicornis which
is presently exported in good quantities to countries like Japan.
