Indicus shrimp is one of the pond cultivation commodities which is expected to become a favorite for Indonesian fisheries exports, however its development is currently still limited. Therefore, efforts to revive indicus shrimp cultivation can be done by encouraging the supply of quality indicus shrimp parents, one of which is through domestication efforts. This test aims to determine the progress of indicus shrimp domestication efforts at Jepara Brackish Water Aquaculture Development Center. Identification of morphometric diversity is carried out by calculating the diversity coefficient. The method used is truss morphometry. There were 15 shrimp samples tested for each male and female in G-1 and G-2. The lifespan of shrimp ranges from 6-7 months with an average total length of female shrimp 12-15 cm and male shrimp 15-18 cm. There were 19 landmarks and 42 morphometric characters measured on the shrimp body surface. Measurements are carried out digitally.
The test results showed that the diversity coefficient of G-1 and G-2 indicus shrimp was relatively low because it was in the range of 2-18%. The results indicate that indicus shrimp populations tend to be homogeneous and uniform. However, there was an increase in the average diversity coefficient from the G-1 population (5.8%) to G-2 (7.6%).
