Abstract

Results of a preliminary study of the distribution and abundance of the swarming crab Charybdis (Goniohellenus) smithii Macleay in the Deep Scattering Layers on the west coast of India are presented based on the analysis of 244 IKMT samples collected by FORV Sagar Sampada during February, 1985 to January, 1986. The swarming crab is found to exist though out the west coast of India as against its known distributional limit in the north upto Bhatkal in Karnataka coast. Maximum density was observed along the southwest coast. The DSL, population included all life stages of the crab such as zoea, megalopa, juvenile, subadult and adult, of which juveniles in the size range 12-20 mm carapace width dominated.
