GROWTH PERFORMANCE CHARACTERISTICS OF BAMBO LOBSTER (PANULIRUS VERSICOLOR) WITH DIFFERENT FEEDING DOSES IN CONTROLLED TANKS

Efforts in pioneering lobster cultivation require information on the maintenance of spiny lobsters (Panulirus versicolor), especially the specific feed doses required for their growth. This study aims to obtain information about the ideal feed dose for spiny lobster (Panulirus versicolor) growth and survival. The samples included spiny lobsters (Panulirus versicolor), which were obtained from the fishermen’s catch and lands on Osi Island, West Seram Regency, Maluku Province. Each tank consisted of 8 samples with an initial weight between 600-650 gr. This research was conducted for six months, and utilized specific doses of feed as a treatment: A: 3%, B: 5%, C: 7% of the tested lobster's bodyweight. Furthermore, the physical boundaries measured include Specific Growth Rate (%), absolute growth, and water quality maintenance. The results showed that lobsters fed with a dose of 5% had a significant weight gain compared to the 3% and 7% doses. Therefore, the SGR was higher for lobsters fed at a dose of 5% (5.83%), followed by the ones treated with 7% (5.64%) and 3% (4.42%). In comparison, for the absolute growth average, the best treatment dose was 5% (75.82gr), followed by that of 3% (69.97gr) and 7% (57.55 gr). From the results, it can be concluded that a feed dose of 5% of body weight provides a relatively high growth rate compared to other treatments. Therefore, the optimal feed dose for the cultivation of spiny lobster (Panulirus versicolor) is 5%.
