The nature of cannibalism in snakehead fish (Channa stiata) causes high mortality in snakehead fish farming. Good and proper management is needed to minimize its cannibalism. The aims of this research were intended to find out the feeding frequency and feeding rate in growth performance and survival rate of snakehead fish seed. This research was conducted with Factorial Completely Randomized Design (FCRD), which consisted of 2 factors, feeding rate and feeding frequency each with triplicates. The treatments of feeding rate were 3%, 5%, and 7% and the treatments of feeding frequency were 3 and 4 times everyday. The used feed is commercial feed PF-800. The result of this research indicated that feeding rate 7% with 4 times feeding frequency each day was the highest absolute weight and length of growth rate than the other treatments. The highest value in survival rate parameter was feeding rate 3% with 3 and 4 times/day. On the other hand, the lowest value in FCR parameter was feeding rate 5% with 3 times feeding frequency each day. Meanwhile, the highest value in protein retention parameter was feeding rate 5% with 3 times/day. The result showed that there was any interaction in absolute weight of growth rate and protein retention. The single factor in form of feeding rate gave significant results of survival value and feed conversion ratio. The result of this research showed that feed management of 7% FR with 4 times/day FF gave the best result in growth, FCR, and protein efficiency of snakehead fish. Although, it has the lowest SR value, but 7% FR with 4 times/day FF can produce the highest biomass of snakehead fish in this study reached 114,45g.

Snakehead (Channa sp.) was one of the superior freshwater fish species native to Indonesia that has been successfully domesticated. The increasing demand for snakehead fish on the market has resulted in the addition of cultivated land and water use. Aquaponics technology was a combination of fish farming and plants that grow without soil media. The aim of this research was to determine the best composition of probiotics that can be used in aquaponic technology to optimize growth rate and feed conversion of snakehead fish (Channa sp.). This research used an experimental method. The experimental design used was a completely randomized design with four probiotic combination treatments and each treatment was repeated three times. The results showed that awarding of different probiotic compositions in the aquaponic system resulted in a spesific growth rate that was not significantly (P>0.05) different between treatments. The highest value of spesific growth rate were in the treatment of probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae with a value of 4.11%/ day. Awarding of different probiotic compositions in the aquaponic system results in significantly (P<0.05) different feed conversion ratio values. The best feed conversion ratio values were in the treatment of probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae with a value of 1.78. The conclusion of this study was the composition of probiotic Lactobacillus casei and Saccharomyces cerevisiae was the best probiotic composition to increase the spesific growth rate and feed conversion ratio of snakehead fish.

Stocking density is an important factor in cultivation, it can save land use, and increase the efficiency of fish farming. The purpose of this research was to determine the different density information on tilapia seeds measuring 2-3 cm as an alternative to using tilapia (O. niloticus) seeds 7-9 cm in size so that they can be developed in Batur Lake. The research was conducted in January - March 2020 in the floating net cages in Trunyan Kintamani village, Bangli, Bali. The research used a completely randomized design method with three treatments and three repetitions. The Tilapia seeds used are 2-3 cm with different stocking densities, 100 ind/m3, 150 ind/m3, and 200 ind/m3. The parameters observed were SGR (Specific Growth Rate), absolute growth, SR (Survival Rate), FCR (Feed Conversion Ratio), and water quality including temperature, DO, pH, TDS. The results of this study indicated that stocking density did not have a significant effect on the growth and survival rate of tilapia seeds, because the temperature was too cold so that the tilapia seeds failed to adapt properly at the beginning of stocking and the physiological conditions of the fish were disturbed so that the fish experienced stress and went to died. Water quality parameters measured include temperature with a range value of 25.86-25.880C, pH with a range value of 9.08-9.13, DO (Dissolved oxygen) with a range value of 7.9-8 mg/L, and TDS (Dissolved solids) with a range value of 1040.25-1041.58 mg/L.
