White-spotted Rabbit fish is a commercial fish that has economic value. This fish is suspected of experiencing population decline due to intensive exploitation. Anticipating population decline that occurs requires a control step that requires information about the individual who is currently in the environment. The purpose of this research is to determine the status of prospective broodstock Rabbitfish fish that are suitable for cultivation. Sampling is done in the Seriwe Bay coastal waters. The research was conducted in the basic and wet laboratory of the fisheries faculty. The method used is the survey method (dependent and descriptive). Examples of fish identified were 50 with 20 males and 30 females, male fish having a total length of 19 cm-29 cm with a weight of 100 grams-300 grams while females had a length of 19 cm-26.20 cm with body weight of 100 gram-310 gram. Data analyzed using a single regression method. With the results of the analysis of the length of weight Ln W = -2.41 + 2.41 Ln L with a hypo allometric growth pattern with a value of b = 2.41, which means that the length increase is more dominant than the weight. Factor condition 1:40 the shape of the fish is less flat and fleshy, unbalanced sex ratio, and mature gonads at TKG IV, fecundity of 110,120 items - 232,400 items. The status of prospective brooders of baronang fish in the East Lombok Seriwe Bay is suitable for cultivation at a size of 23 cm-25 cm. the conclusion of the study is Teluk Seriwe Providing prospective mothers of Rabbitfish fish that are suitable for spawning.
