The objective of this research was to study the suitable model for the use of fermented fish production and golden applesnail in Channa striatus cultivation in aquaponic systems for development into organic aquaculture. Each experiment was fed supplementary diets containing 0, 25, 50% replacement of fishmeal by golden applesnail and fermented fish production while the control was fed with instant food under the aquaponic system. Experiment 1 raised C. striatus from 3 inches to 6 inches over a three-month period. The density rate is 100 fish/square meter. At the end of the experiment, it was found that the control and experiments fed with 25 and 50% golden applesnail and fermented fish production gave the maximum weight gain of 78.15 + 2.47 g and 76.92 + 2.11 g. When comparing the statistical means, there was no difference (p > 0.05) in survival rates. And the specific growth rate of the control gave the highest mean of 67.15 percent and 2.87 + 1.97 percent per day. Experiment 2 Raised C. striatus fish from 6 inches in size to market demand for 3 months at a density rate of 50 fish/square meter At the end of the experiment, it was found that the control gave the maximum weight gain of 175.28 + 4.12 grams., not different from the experiments fed with 25 and 50 percent golden applesnail and fermented fish production mixtures with values of 160.13 + 4.17 and 165.23+. 7.11 g, respectively (p < 0.05), the survival rates of control and specific growth rates were 62.38 + 1.14 percent and 2.98 + 2.27 percent per day, respectively. The water quality of all experiments was not different (p > 0.05).
The results of the study show that the use of replacement of fishmeal by golden applesnail and fermented fish production in a dietary formula for C. striatus farming can be used as a guideline for the development of other carnivorous fish farming.
