Abstract

ABSTRACT                             Integrated Multi-Tropic Aquaculture (IMTA) is a cultivation system in which organic waste from cultivation activities can be utilized by other biota in one container so as to reduce the environmental impact of cultivation activities. Organic waste can be utilized as the growth of phytoplankton which will be used other biota as natural food. This research is focused on the species of tiger shrimp (P. monodon) as the main cultivated commodity, while the green mussels (P. viridis) is one of the biota that can utilize the phytoplankton that flourish because of organic waste in the waters. The purpose of the study is to determine the effect of green mussel stock density on the growth and survival rate of tiger shrimp with IMTA system. The tiger shrimp used were stadia postlarvae (PL30) with size 0.11 - 0.14 gram /shrimp. The stocking density is 80 tiger shrimps per container with 1m2 container size. This study used a complete randomized design study (RAL) with 5 treatments and 3 replications. The stocking density of the green mussel being used as treatment are 0, 30, 45, 60, and 70 green mussels per container. The results showed that the average growth rate of tiger shrimp in treatment A (with stocking density of 0 green mussels) was 22,06±0,18%/day, treatment B (with stocking density of 30 green mussels) was 28.89±0.20%/day, treatment C (with stocking density of 45 green mussels) was 27.09±0.20%/day, treatment D (with stocking density of 60 green mussels) was 25.32±0.21%/day and treatment E (with stocking density of 75 green mussels) was 23.92±0.12%/day. The average value of tiger shrimp survival rate on B was 80.00%, A was 78.33%, C was 77.92%, D was 74.58% and E was 61.25%. The best green mussels stocking density for tiger shrimp growth and survival rate is with stocking density of 30 green mussels (treatment B). Keyword: Growth, Survival Rate, Green Mussel, Tiger Shrimp, IMTA

Abstract

Tiger shrimp is a commodity pond that has high economic value compared to others. Tiger shrimp culture can be done by using a monoculture system, a polyculture system or an Integrated Multi-trophic Aquaculture (IMTA) system. IMTA system is one solution to reduce the environmental impact of cultivation activities because undigested feed and metabolism results in an accumulation of feces in the pond. This study aims to determine the effect of the addition of seaweed into the system on the growth and survival rate of tiger shrimp and also to determine the best density of seaweed in controlling the water quality. The research was conducted from September 2017 to November 2017 in Tambak Bulusan Village, Demak, Central Java. The material used is seaweed. Tiger shrimp used in size PL 30 measuring 2.0-2.9 cm. In length the stocking density is 80 individuals/m. The feed used is pellets given by using a fixed feeding rate of 5%. This research used an experimental method with complete randomized design with 5 treatments and 3 replications. The treatment of seaweed stocking used is 50 g, 100 g, 150 g, and 200 g. The results showed that different stocking of seaweed had significant effect on growth of weight, relative growth rate, survival rate of tiger shrimp. The best treatment of seaweed density is treatment  A1 (50 gram), treatment A1 can increase the value of tiger shrimp growth with absolute weight of 1.67 ± 0.05 gram; the relative growth rate of 36.36 ± 1.04 %; and the survival rate of 78.75 ± 1.25 %. While the best growth value of seaweed is at treatment A1 (50 gram) with weight growth value of 73,21 ± 4,26 gram, and daily growth rate of 2,15 ± 0,08 %/day. Seaweed can balance the quality of waters with the results of nitrate water quality of 0.02 mg / L - 0.08 mg / L, nitrites of 0.00 - 0.42 mg / l, and ammonia levels of 0.02 - 0.59 mg / l. The results are quite feasible for shrimp farming activities.Keywords: growth, Penaeus monodon, Gracilaria sp., IMTA
