Comparison of Plankton Abundance, Water Condition, Organism Growth Performance of Vaname Shrimp (Litopenaeus Vannameiei) on Intensive and Extensive Culture Systems in Banyuwangi District

Litopenaeus Vannameiei is one type of shrimp that is often cultivated in Indonesia. The culture system model consists of extensive (traditional) and intensive system. This study aims to determine the comparison of plankton abundance, water conditions, organisms growth performance of Litopenaeus Vannameiei on intensive and extensive aquaculture systems in the waters of Banyuwangi Regency. The parameters measured are physical and chemical parameters including temperature, brightness, pH, dissolved oxygen, salinity, ammonia, alkalinity, type and abundance of plankton. The analysis method is plankton abundance, productivity analysis, SR, FCR and vaname shrimp growth. The results showed that 4 classes of plankton in intensive pond waters were identified namely Chlorophyta, Cyanophyta and Chrysophyta phytoplankton, while Protozoa class zooplankton. In traditional ponds not much different, there is only Crpytophyta class as an additional identification result. Plankton abundance in intensive ponds reaches 27,595 individuals per liter, while for extensive ponds plankton abundance reaches 37,641 individuals per liter. The survival rate of shrimp in intensive ponds is around 86% while extensive ponds are 67%. FCR value of extensive ponds 1.02, while intensive ponds FCR value of 1.17. The average final weight of shrimp on intensive ponds was 11.76 g/head and on extensive ponds which was 8.33 g/head.
