Results of the tagging experiments on the Indian Spiny lobster, Panulirus homarus (Linnaeus) — Movement and growth

Abstract

Mark-recovery experiments conducted with the help of suture tags on Indian spiny lobster Panulirus homarus (Linn.) showed that their movement in the fishing ground is of a very restricted nature. Long migratory movements were not observed. The species grows very fast and attains commercial size by the end of first year after the puerulus stage settles down to the bottom of the fishing ground. The growth rate slows down after the second year! Sizes attained at successive ages have been estimated with the help of von Bertalanffy's growth equation. The commercial fishery is largely supported by 1 st and 2nd year animals.
