Abstract

The growth and moulting of three species of Panulirzcs, :lamely Panulirus homarus (Linnaeus), Panulirus ornatus (Fabricius) had Panulirus penicillatus (Olivier) in captivity have been studied. The average growth increment per moult was 2.3-3.4 mm carapace length (6.9-9.6 mm total length) for male and 2.3-3.0 mrn C.L. (6.5-9J lam T.L.) for femzb P. homarus, 2.7 mm C.L. (111.3 mm T.L.) for male and 3.3-4.4 mm C.L. (111 ,843.8 mm T.L.) for female P. ornutus and 1.5 nun C.L. (5.5 mm T.L.) for male P. penicillatus. The growth rate has been found 60 be higher in younger individuals than in older ones. P. homarus moulted eight timw in about fifteen months, P. ornatus moulted sewn times and P. penicillatzrs six times in albout twe3tyom months. An instance of breeding in captivity i % P. homarus is reported. The prospects for culturing lobsters in Mandapam area are indicated.
