LENGTH-WEIGHT RELATIONSHIP OF SPINY LOBSTER, PANULIRUS HOMARUS POPULATION INHABITING SOUTHERN COASTAL REGION OF SRI LANKA

Abstract: Scalloped spiny lobster, Panulirus homarus is one of the most commercially important lobster species out of six spiny lobsters recorded from southern coastal region of Sri Lanak. A total of two hundred and fifty specimens were subjected to the study along southern coastal waters during the time period from January 2012 to January 2013. Growth pattern and relationships of total-length with body weight and carapace- length with body-weight of Panulirus homarus were studied for male, female and total population separately. Regression equations for total-length and body weight for male, female and total P. homarus population were W = 0.000016T
