AbstractSnakehead fish (Channa sp.) is one of Indonesia's native freshwater commodities that has been successfully domesticated by fish farmers, yet the domesticated snakehead fish culture still has problems, namely the low survival and growth of local snakehead fish. Overcoming this problem requires a technology that can optimize the survival and growth of the domesticated snakehead fish (Channa sp.). One technology that can be applied is the use of probiotics. This reserach aimed to examine different probiotics through feed to optimize the survival and growth of domesticated snakehead fish (Channa sp.). This research was conducted with an experimental method. The experimental design used was a completely randomized design with 4 treatments and 3 replications. The treatments were control treatment (P0), treatment with probiotic composition of Lactobacillus sp., Bacillus spp. and Nitrosomonas sp. (P1), treatment with probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae (P2), and treatment with probiotic composition of Lactobacillus sp., Acetobacter, Rhodobacter sp., yeast (P3). The results showed that different probiotic feeding had a significant effect (P<0.05) on the survival parameters and different probiotic feeding compositions had no significant effect (P>0.05) on the growth parameters. The composition of Lactobacillus casei and Saccharomyces cerevisiae probiotics is the best probiotic composition to increase survival and growth of domesticated snakehead fish.Keywords: Domestication, Growth, Survival Rate, Probiotic

Siamese pangasius fish (Pangasius hypophthalmus) is a freshwater fish species originated from species introduced and has economic value for cultivation. This study aimed to analysed the administration of different commercial probiotics through feed on the survival rate and feed efficiency of Siamese pangasius fish. This research was conducted in the hatchery of Teuku Umar University. The method used a completely randomized design with 4 treatments and 3 replications. The treatments were control/administration of Mina Pro (P0) commercial probiotic, administration of Raja Grameh (P1) commercial probiotic, administration of EM4 (P2) commercial probiotic and administration of Boster (P3) commercial probiotic. Parameters observed were survival, feed efficiency, and water quality. Data were analysed using analysis of variance; for different treatments, Duncan's test was carried out. The results showed that the administration of different commercial probiotics had a significant (P<0.05) effect on feed efficiency but had no significant effect (P>0.005) on the survival rate of Siamese pangasius fish. Raja Grameh's commercial probiotic with the composition of Rhodobacter sp., Lactobacillus sp., Acetobacter sp., and yeast were the best commercial probiotic to increase the growth and feed efficiency of Siamese pangasius fish

This study aimed to examine the effect of application of different stocking densities in budikdamber system on the survival rate and growth of silver catfish (Pangasius djambal). The non-factorial Complete Randomized Design (RAL) used in this study consisted of four treatments and three tests. The treatments studied were the application of a stocking density of 5 fishes/container (P1), 10 fishes/container (P2), 15 fishes/container (P3), and 20 fishes/container (P4). The silver catfish used in this study was 6-8 cm in size. The maintenance period of silver catfish in this study was in 40 days. The research parameters that measured in this study were survival rate, absolute weight growth, absolute length growth, specific growth rate and water quality. The results of analysis of variance (ANOVA) showed that different stocking densities on rearing media with the “Budikdamber” system had no significant effect for survival rate, absolute weight growth and specific growth rate of silver catfish (Pangasius djambal), but had a significant effect on absolute length of silver catfish (Pangasius djambal). The best stocking density to increase the absolute length growth of silver catfish is 15 fishes / container (P3) in number 7.36 cm.

One of the freshwater fish that has an economical price and is endemic to the lake, Ie Sayang, is Rasbora sp. Generally, fish from farms are calmer and relatively less stressful in terms of transport. This research was conducted to determine the amount of different Total density on the survival rate of bileh fish (Rasbora sp.). This research is an experimental research with 4 trials and 3 repetitions. The experiments that were applied to this research were: P1 = number of fish 25 fish/l; P2 = number of fish 50 fish/l; P3 = number of fish 75 fish/l and P4 = number of fish 100 fish/l. The survival data of fish during further research was carried out by Anova analysis. The results of this research are that the highest average survival rate for bileh fish is P4 of 99.67% and average high ammonia value was obtained in experiment 4 of 2.87 ppm.
