Effect of feeding frequency on survival and growth of juvenile spiny lobster Panulirus versicolor in Indonesia
Journal Publication ResearchOnline@JCUAbstract
This research aimed to assess the effect of feeding frequency on survival and growth of juvenile bamboo spiny lobster Panulirus versicolor (Latreille, 1804). A completely randomized design of 4 treatments with 4 replicates was used with treatments consisting of: feeding once per day (FR1), feeding twice per day (FR2); feeding three times per day (FR3) and feeding four times per day (FR4). The experiment was performed in a tank system with a recirculating water supply. Sixteen 100 litre tanks were stocked with post-puerulus juveniles, mean weight 0.50±0.01 g, at a density of 89 m-2 and the experiment ran for 30 days. Diet consisted of a manufactured pellet diet formulated for tropical spiny lobster. Results indicated a statistically significant effect (p < 0.05) of feeding frequency on carapace length, although not for other variables. Carapace length for feeding two and four times per day was significantly greater than for feeding once per day. Mean survival rate across all treatments was 32% and mean final weight was 0.95 g. Notwithstanding the statistical non-significance for several of the variables, the significant effect on carapace length and trends evident for the other variables suggest feeding more than once per day may be beneficial.
