Description A detailed investigation was undertaken for a period of 20 months from
October 2013 to May 2015 to study the landing characteristics and
species diversity of sea urchins in two landing centresviz., Pampan and
Vedalai along the Mandapam coast of Gulf of Mannar. A total of 16
species of regular sea urchin have been documented during the study
period. The species S. virgulata and T. toreumaticus were abundant in
the catch between December and March period and the maximum total
landing were found to be 7,239 kg and 3,103 Kg respectively in the trawl
landing at Pampan. The landings were estimated to be 2,819 kg of S.
virgulata and 1,208 kg of T. toreumaticus at Vedalai, which is a major
bottom set gill net landing centre. The species composition of these two
species were analysed to be 70:30 for S. virgulata and T. toreumaticus
respectively in the landings. The morphometric study revealed that the
overall population showed a great concentration of lengths within the
diameter classes 20 – 60 mm for S. virgulata and 20 – 45 mm for T.
toreumaticus.
