Kajian Fisiologis Ikan Selais (Ompok Hypophthalmus) Dengan Sistem Resirkulasi Akuakultur (SRA)

---

Ompok hypophthalmus is an endemic fish from that is has high economic. Intensive cultivation of this Ompok hypophthalmus with high stocking density requires large amounts of feed. The remaining feed can cause the water quality to decrease, if the water quality is disturbed, the physiological and haematological conditions of the fish can be disturbed, aquaculture technology is needed to overcome it. The aquaculture recirculation system technology is expected to be a solution to the problem of intensive fish farming. This research was conducted on October 6th – December 6th 2019, at the Laboratory of Aquaculture Technology, Faculty of Fisheries and Marine, Riau University. The purpose of this study was to determine the effect of stocking density on water quality in the Aquaculture Resisculation System technology and to determine the effect of water quality on Recirculation aquaculture system on the physiology and haematology of selais fish.
This study used an experimental method with a completely randomized design, three treatments and three replications. The treatment of stocking density for Ompok hypophthalmus in this study was P1 200 fish/m3, P2 250 fish/m3, P3 300 fish/m3. This research was conducted in two stages, the first stage with the design of the container to the formation of a biofilter and determining the water flow rate. The second stage of cultivating the Ompok hypophthalmus. The data tested included total erythrocytes, hemoglobin levels, hematocrit levels, total leukocytes, glucose levels, absolute growth, feed efficiency using one way ANOVA at a 95% confidence level and analyzed with the SPSS 17.0 application program. Data on the level of oxygen consumption, cortisol hormone, minerals, water quality, survival rate are presented in graphs and tables then analyzed descriptively.
The results showed that the water in the aquaculture container was still optimal for cultivating Ompok hypophthalmus and the recommended stocking density was 250 fish/m3, with the lowest oxygen consumption level 0.021 mg O2/g body weight/hour at the start of maintenance and the highest oxygen consumption level 0.051 mg O2/g body weight/hour at the end of the study. Total erythrocytes 264.00±3.00x104 cells/mm3, Hemoglobin 8.3±0.11 g/dL, Hematocrit 26.66 ± 0.57%, Total Leukocytes 2.53±0.01x104 cells/mm3, Blood glucose 89.00±1.00 mg/dL, Cortisol 53.3 ng/mL, Absolute Weight Growth 12.06±0.02 g, Absolute Length 7.44±0.02 cm, Spesific Growth Rate 2.40±0.01 %, Calcium in serum 11.1 mg/dL, Feed Efficiency 81.59 ± 1.17%, Food Convertion Ratio 1.22 ± 0.01 and Survival Rate was 100%.
