Abstract: The present study explores the local knowledge held by fishers of Ratnagiri coast about the ecology and biology of mud crab Scylla serrata, an important food species to the local people. It attempts to address the differences and similarities between the information provided by fishers with published biological data about mud crab. A total of about 30 fishers resorting to traditional crab fishery were interviewed using semi structure interview schedule incorporating all the items on which the information was needed. Similarities were noted in respect with habitat, migratory movement for feeding, burrowing habit, size at first maturity and peak spawning season suggesting general pattern. The information provided by the fishers also included differences with published data with respect to breeding migration and feeding preferences of mud crab. Abundance of Scylla serrata along with edible oysters was noted by most fishers. Apart from this, the effect of various ecological phenomenon such as rainfall, light, temperature, tides and lunar cycle on the behavior, condition and availability of mud crab was studied. Local ecological knowledge held by fishers agrees with available Scientific literature about Scylla serrata providing hypotheses to be investigated through biological research. The present study highlights some contributions the fishers’ local knowledge may give to local management of Scylla serrata, such as to improve the Scientific knowledge and sensitize the Scientists to local conditions as well as promote the interaction between fishers and Scientists.
