| Abstract | ||
| This research aimed to show the natural feed effect on improved matured ovary broodstock mud crab (Scylla serrata). The research was conducted on Tarakan Island, North Kalimantan, Indonesia. The mud crabs used consisted of heads, weighing 300-400g, with the ovary at maturity level II stage. The feed used in this study consisted of fresh ingredients, including anadara shellfish (Anadara granulosa), seaworms (Polychaeta), and beef liver. These ingredients are available in large quantities and have not been used for mud crab broodstock. The parameters observed include ovarian maturity, fecundity, and water quality. This study used a complete randomized design (RAL) with three treatments and six repeats. An analysis of data on the acceleration of the ovary maturity rate was carried out using ANOVA. The treatment differentiation of fresh feed resulted in a significant (P<0.05) time maturity ovarium. A. Granulosa feeding is considered extremely good for triggering the acceleration of berries in mud crab broodstock ovary. Fresh feed treatment provides different fecundity values for mud crab broodstock, but based on ANOVA analysis, it shows no different results. Feeding fresh Anadara granulosa and beef liver clams accelerates the development of mud crab ovary compared to other diets. These ingredients have higher levels of proteins and a total lipid, making them beneficial for the formulated diet of mud crab broodstock. | ||
