The data on crab landings of our country is essential to know the contribution of crabs to the Indian
economy, but there is no clear cut intimation on the landings of the crabs from Arukkattuthurai to
Aiyammpattinam, south east coast of India. So in the present study, it is aimed to assess the fishery resources
of the six landings from Arukkattuthurai to Aiyammpattinam for a period of one year (from September 2007
to August, 2008). There are about 12 commercially important crabs were reported in almost all the stations. The
crab, C. truncata was less in A rukkattuthurai (301.6 kg), Pointcalimere (331.9 kg) and Aiyammpattinam (392.7
kg). However, C. gladiator was available less in Mallipattinam (318.9 kg) and Manamelkudi (354.5kg) and
C. lucifera in Kattumavadi (333.7 kg). The total contribution of crabs (80,554.34 kg), males (38,542.55 kg),
females (30,842.25 kg) and berried females (11,169.59 kg) are maximum in Mallipattinam than other stations.
However, Kattumavadi centre standing final place in total male (23,718.27kg), female (17, 960.00 kg), berried
female (6,015.296 kg) and total crabs (47, 693.492 kg) landed. The conservation measures for catching young,
undersized and berried crabs should be done by educating the fishermen through audiovisual aids. Sea ranching
should be promoted for over exploited species. And certain regulatory measures and laws should be enforced
like, fixing legal minimum size and protection of ovigerous crabs. The law breakers should be fined or
punished.
Key words: Crustaceans, P.pelagicus, P. sanguinolentus, S. tranquebarica, S. serrata, berried female, audio visually aids
