Abstract

Water quality plays an important role in super-intensive vannamei shrimp cultivation because it can affect growth and survival performance, so its management needs to be considered optimally. Application of Bacillus subtilis bacteria can suppress the development of Vibrio sp. and also can stabilize plankton growth and maintain the balance of pond water quality. The purpose of this study is to determine the optimization of water quality management on the growth performance and survival rate of vannamei shrimp Litopenaeus vannamei at Marine Science Techno Park, Diponegoro University. This research method is a case study that includes interviews, observations, and following all stages in the process of vannamei shrimp production at Marine Science Techno Park, Diponegoro University. Water quality management in vannamei shrimp ponds includes treatments of water change, sipon, calcification, probiotics, and monitoring of water quality parameters. The results showed optimization of water quality management with the application of several routine treatments, showing temperature values of 26.50 – 28.80°C; pH 7.75 – 8.55; brightness 28.00 – 45.00 cm; salinity 10.00 – 35.00 g/L; dissolved oxygen 3.99 – 4.58 mg/L; alkalinity 134.00 – 164.00 mg/L; nitrite 0.00 – 0.60 mg/L; and water color ranges from light green, brown, brownish green. Optimization of water quality management in shrimp production with the application of several routine treatments can improve growth performance with ABW 17.91 g/ind, ADG 0.36 g/day, and survival 57.16% with a harvest size of 50 – 55.

Abstract

Vannamei shrimp Litopenaeus vannamei is one of the leading fishery commodities that have high economic value. The very high market demand for vannamei shrimp makes farmers carry out intensive cultivation with the addition of probiotics, in order to produce high productivity. This study aims to determine the productivity of vannamei shrimp in intensive cultivation with the addition of probiotics. This research method is a case study that includes interviews, observations, and following all stages in the process of vannamei shrimp production at CV. Daun Prima. Techniques of vannamei shrimp cultivation include pond preparation, media preparation, fry selection and stocking, feed management, water quality management, growth monitoring, pest and disease monitoring, and harvesting. The treatment used is the administration of probiotics containing bacteria Bacillus sp., Lactobacillus sp., Nitrosomonas, and Nitrobacter which function to optimize shrimp growth and maintain stable water quality. Shrimp production performance during 77 days of maintenance yielded SR 87%; biomass 2.8 tons; harvest size 66; ABW 15.15 grams/ind; ADG 0.23 grams/day; and FCR 1.12. Water quality during maintenance is within the optimum range to support shrimp growth, including temperature 28 – 31 °C; brightness 22 – 44 cm; pH 7.6 – 8.4; salinity 30 – 32 g/L; and dissolved oxygen 4.4 – 5.3 mg/L. Vaname shrimp cultivation with intensive technology with the addition of probiotics applied at CV. Daun Prima shows optimal productivity.
