Abstract

Mud crab (Scylla sp.) is a fishery commodity that has high economic value and is one of the superior fishery products. The demand for mud crabs continues to increase, so intensive cultivation efforts are needed. Mangrove crabs have high economic value. However, farmers often face problems in cultivating mud crabs, namely molting, which takes a long time, resulting in non-uniform growth. Therefore, this research aims to optimize the speed of skin turnover and uniform growth with an alternative technology for dosing spinach leaf extract, which can be applied via injection. The research method used was a Completely Randomized Design (CRD) method with 4 treatments and 3 replications. The treatments to be carried out are: P0 = (control), P1 (spinach leaf extract 3 µl/g), P2 (spinach leaf extract 5 µl/g), and P3 (spinach leaf extract 7 µl/g). Parameters observed: Daily growth rate, feed conversion ratio, molting percentage, survival rate (SR), and water quality observations. The results of the research were that the effect of giving red spinach leaf extract (Amaranthus tricolor) on the molting success of mud crabs (Scylla serrata) had a very significant effect on Daily Growth Rate (LPH), Feed Conversion Ratio (FCR), and Molting Percentage. However, it did not have a real effect on the Survival Rate (SR) of mud crabs (Scylla serrata).
