Potensial yield of deep sea shrimp resources in the Southern Java of the Indian Ocean EEZ waters

Study on potential yield of deep sea shrimp in the South of Java waters (Indian Ocean) was carried out based on data collected from the survey conducted between May and June 2005 using Baruna Jaya IV research vessel. This study basically conducted by applying swept area method. The result showed that the population of deep sea shrimp in this area was Penaeid shrimp, Caridean shrimp and Scampi. The species composition of deep sea shrimp were consist of 38 species and the catch of shrimp was dominated by scarlet shrimp (Plesiopenaeus edwardsianus) about 26.04% and stout red shrimp (Aristeus virilis) about 12.59%. Distribution of this resources is more in east area (Southern of Yogyakarta to Pacitan) and rarely at west area (Southern of Cilacap to Kebumen). The highest abundance of deep sea resources were caught on the depth 200 until 500 m and the lowest on the depth 500 until 750 m. Stock density this resource in this area ranged between 7.8 and 311.9 kg km super(-2) and the biomass in this area was 1.232 ton with potential yield was around 616 ton per year.
