Coastal
environment provides a greater range of habitats and thus potentially supports
greater biodiversity. Before starting to produce seeds in a hatchery and
culture them in ponds, thorough knowledge about their distribution in nature is
important. So the present study is aimed to know the biodiversity of crabs from
Arukkattuthurai to Pasipattinam. Totally 79 individual crab species were
recorded belonging to 21 families from all 10 stations. Maximum crab species
were recorded belonging to the family Portunidae than others families and also
the maximum number of crab species 163 were recorded in Mallipattinam
(station5) and minimum 69 species in Pasipattinam (station10). Occurrence of
crab species in different stations were in the following order; Mallipattinam
(163) > Sethubavachatram (161) > Manamelkudi (127) > Pointcalimere
(117) > Muthupettai (116) > Jegathapattinam (110) > Kattumavadi (101)
> Arukkattuthurai (92) > Adirampattinam (85) > Pasipattinam (69).
Crabs were collected plenty during summer and monsoon than pre-monsoon and
post-monsoon. The crabs belonging to families viz., Calappidae,
Portunidae, Potamidae, Grapsidae, Sesarmidae and Ocypodidae were obtained
almost all seasons.
