Abstract

Ornate Spiny Lobster (P. ornatus) are a high value aquaculture commodity that faces cannibalism issues when kept in groups. This study aims to evaluate the effectiveness of solitary rearing of Ornate Spiny Lobsters (P. ornatus). This study aimed to rear lobsters (P. ornatus) at three different depths (3 m, 4 m, and 5 m) and two rearing locations, namely floating net cages (KJA) with and without ornamental fish in Inner Ambon Bay. The study was conducted for 90 days using 3 × 2 factorial design and two-way analysis of variance (ANOVA). The results showed that the survival rate (SR) in all treatments reached 100%, indicating the effectiveness of the solitary system in suppressing cannibalism. There were no significant differences in absolute weight growth based on depth and rearing location. However, specific growth rate (SGR) data showed significant differences based on location, where lobsters reared in KJA without ornamental fish had higher SGR values than those reared with ornamental fish. Rearing depth and the interaction between depth and location did not significantly affect growth parameters. This study shows that the solitary rearing method at a depth of 3–5 meters, especially in KJA without ornamental fish, is an effective approach to increase the survival and growth of Ornamental Spiny Lobster (P. ornatus) in the waters of Inner Ambon Bay.
