Among the edible marine crustaceans of India, crabs ranks third by virtue of their importance as an
esteemed gourmet and the value of fishery they support, while shrimps and lobsters occupy the first and second
places respectively. Among the commercially important crabs, the genus Scylla ranks first followed by
Portunus sp. (P. pelagicus and P. sanguinolentus). In the present investigation an attem pt has been made to
study the fishery potential of commercially important portunid crab along Parangipettai coast. The data showed
that P. sanguinolentus appears to breed round the year. The total landings along with the ovigerous female
crabs, during the study period were estimated as 31,817 kg (31.8 tons) from February 2004 to December 2004
and 26,588.1 kg (26.58 tons) from May 2005 to January 2006. The shortage of four fishing months (from
January 2005 to April 2005) during the study period was due to the heavy destruction caused by tsunami on
26th December 2004. The Killer waves caused heavy damages to coastal livelihood. Fisherman loss their craft
and gear very particularly along Nagapattinam and Cuddalore districts of Tamil Nadu coast where the study
area is located. The berried crabs were recorded round the year with two seasonal peaks from February 2004
to May 2004 and from August 2004 to December 2004 for the first year. How ever, during the second year from
May 2005 to June 2005 and the second peak is from August 2005 to December 2005. The ovigerous female
crab landings were recorded as 5,193.7 kg (5.19 tons) from February 2004 to December 2004 and 4,337.6 kg
(4.33 tons) during the second year from May 2005 to January 2006.
