Population estimation of Horseshoe crab Tachypleus gigas by capture-recapture method at Chandipur sea shore (Orissa), India.

R. Debenath and A. Choudhury

Population of horse-shoe crab Tachypleus gigas (Miiller) was estimated at Chandipur sea shore with the help of Jackson's capture-recapture method. Horse-shoe crabs came to breed in high tide zone associated with the full moon tides. The capture marking release data showed that maximum 6,000 animals came to the breeding beach on 9th March. Some sort of sexual selection and dispersal phenomena had also been recognised from this field experiment.
