Abstract

The by-catch landed by trawlers in Kerala coast was studied during April 2005 to May 2006 to estimate the diversity of brachyuran crabs. Forty three species of brachyuran crabs represented under 11 families and 22 genera were recorded from the trawl by-catch, including eight commercially
exploited species. One species each was recorded under the crab families such as Dromidae, Dorippidae, Graspidae and Corystidae while Portunidae was represented by 16 species. The species diversity and abundance was more at Neendakara and results of cluster analysis showed that Neendakara and Munambam fishing harbours were similar in species composition. The species
composition was also found to vary with seasons with more species diversity during the monsoon
