Abstract

The use of seaweed as ecological tools for improving environmental condition has been proved to sustain shrimp production. However, adding too much seaweeds caused oxygen depletion and nutritional competition. The objective of this study was to determine the optimum density of G. verucosa for supporting the growth of monodon shrimp. The research was conducted in Tambakbulusan village, Demak Regency with 20 fiber semi outdoor tanks. The tanks were used for the experiment without seaweed and with four densities of seaweed (50, 100, 150 and 200 g.m-2) using hanging rope and were co-cultivated with 80 individuals of post larva (2.0-2.9 g) monodon shrimp in 800 L brackish-water system. The concentration of TAN, NO3, and NO2 were monitored every week, while dissolved oxygen (DO), pH, temperature, and salinity werechecked daily for 30 days. The highest shrimp survival rate (79.75%) and growth rate (6.6%day-1) were obtained in the 100 g.m-2 of G. verucosa, significantly higher than in other treatments. Furthermore, seaweed density has a decreasing effect of NO3 content (g/L) in RL100 from 0.26 to 0.16. and the lowest concentration of NO2 and NO3 were determined. Conversely, the highest density of seaweed (200 g m-2) gave the lowest survival rate of shrimp (53.67%) due to high NO2 content. DO had various values depending on the density and drop to less than 3.5 ppm in the highest density. In all treatments,  pH, temperature and salinity werein a good range for shrimp culture. Thus, 100 g.m-2 of seaweed was optimal for ensuring the function as nutrient removal in shrimp co-culture.

Penelitian ini bertujuan untuk mengetahui pengaruh kepadatan terhadap pertumbuhan dan kelulushidupan serta untuk mengetahui kepadatan ikan nila yang memberikan kelulus hidupan dan pertumbuhan terbaik. Metode penelitian dalam penelitian ini menggunakan metode eksperimental dengan rancangan acak lengkap (RAL) dengan mengunakan 3 perlakuan dan 3 kali ulangan. Adapun perlakuan pada penelitian ini adalah sebagai berikut: perlakuan A: Benih ikan Nila dengan padat tebar 67 ekor m-3; perlakuan B: padat tebar 130 ekor m-3 dan perlakuan C: padat tebar 173 ekor m-3. Ikan nila larasati yang dibudidayakan di karamba jaring apung (KJA) dengan padat penebaran 67; 130 dan 173 ekor m-3 menghasilkan bobot, panjang dan pertumbuhan bobot, pertumbuhan panjang, kelangsungan hidup serta konsumsi dan konversi pakan yang berbeda. Hingga kepadatan ikan 130 ekor m-3 nilai variabel biologis tersebut diatas masih baik dan  nilainya mulai terganggu jika kepadatan tebar ikan mencapai 173 ekor m-3. Kualitas air masih dalam kisaran layak. Kata kunci : Nila Larasati, Karamba Jaring Apung (KJA) Commercial Tilapia grow-out by using net cage is limited, while there is still a huge potential to culture freshwater fish. The demand of Tilapia is rising each year following the growth of  world population. Tilapia culture in net cage can hold a higher density. It also has a more stable water quality to enhance production. Information on the optimum density of Tilapia culture in net cage is needed to obtain maximum fish production. This research aims to identify the influence of different density towards the growth and survival rate of Tilapia in net cage and also to identify the density that gives the optimum survival rate and growth. Research method used in this research was experimental design with 3 treatments and 3 replication.. The treatments are: treatment A; Tilapia seed with density of 67 fish seed m-3; treatment B: density of 130 fish seed m-3and treatment C: 173 fish seed m-3 Result shows that Tilapia culture with different density influence growth and survival rate. Until density of 130 m-3, biological variable is in an acceptable range but begin to show a decrease at density of 173 m-3. Water quality is still in normal range. Key words: Tilapia, net cage
