Growth at molt of sub-adult scalloped spiny lobster Panulirus homarus reared in tanks

Abstract Grow-out of lobster performed in a tank culture system offers several advantages over floating sea cage culture, particularly the control environmental factors. However, growth reared tanks need to be evaluated determine rearing period achieve market size. Growth is defined as change size through molting process. Therefore, this study was assess differences weight and length increment at molt male female sub-adult scalloped spiny Panulirus homarus , well annual tanks. Sub-adult lobsters with an initial average 226.18±20.30 g were stocked twenty 4000-L fiber 20 lobsters/tank. Each tagged by photographic method carapace enable identification individual molt, increment. Observation carried out for 42 days rearing. observation showed that between significantly different. The higher (10.00 mm) than those (7.93 (p<0.05). not different sexes. males females 18.53 20.71 g, respectively (p>0.05). In terms increment, both sexes also had fairly similar growth, achieving 168.38 g.yr-1, on average. This found there increased zero declined P. .
