The results of spawning in sangkuriang catfish farming do not always go according to the expected results, as many eggs died before hatcing. Therefore, it is necessary to use spawning hormones which can improve egg quality in order to increase profits in cultivation. This research was aimed to determine the difference on success performance of sangkuriang catfish using HCG, Ovaprim, and Spawnprim. This research used a randomized block design (RAK) with 3 treatments i.e P1 (HCG 500 IU/kg), P2 (Ovaprim 0,5 ml/kg), P3 (Spawnprim 0,5 ml/kg) and 3 groups of repetition i.e K1 (spawning group day-1), K2 (spawning group day-2), and K3 (spawning group day-3). The results of this research showed that using Ovaprim hormone had the highest value than other treatments like on latent time 606±17,78 minutes, egg fertilization percentage 75±2,65%, and egg hatching percentage 69,33±5,69%. Then on egg fecundity and egg diameter showed no significant effect with other treatments.

Betta (Betta sp.) is an anabantidae fish with sexual development that can be directed at the embryonic and larval stages. One way to direct the sex development of these fish is by using hormone therapy using natural ingredients. Coconut water is one of the natural ingredients that can be used because it contains high potassium. This potassium can convert cholesterol in fish body tissue to pregnenolone which will affect the increase in testosterone production. This study aims to determine the best dose and age group in directing the sex of Betta fish experimentally using a randomized block design (RBD) with 4 treatments and 3 replications. The immersion treatment of larvae in the age group of 3 days, 5 days, and 7 days for 15 hours with a dose of 0%, 10%, 20%, and 30% coconut water was carried out in a 3 L jar containing 30 larvae. The results showed that coconut water was able to influence the increase in the percentage of male betta fish (P <0.05) with the highest value at a dose of 30% as much as 86.26 ± 8.34% and the 3 day larvae age group of 72.78 ± 16.03, and have a different effect on other treatments. In addition, the survival calculated after immersion shows a value of 100%, meaning that coconut water does not have a harmful effect on fish. Based on the results of this study, the best treatment for directing the sex of betta fish is a dose of 30% coconut water with the 3 day age group

Utilization of ex-sand pit lakes for aquaculture is difficult due to low water quality and high concentrations of iron (Fe). Phytoremediation using aquatic plants has been proven to be effective in reducing Fe in waters. This study aims to determine the growth, feed conversion efficiency and survival rate of tilapia (Oreochromis niloticus) cultured with ex-sand mining water media with phytoremediation treatment. Phytoremediation treatment was carried out by Eichhornnia crassipes, Azolla pinnata, and Salvinia molesta. Fish culture experiments were carried out in plastic tarpaulin tanks for 40 days, with ad satiation feeding, three times a day using the commercial feed. The results showed that phytoremediation with aquatic plants had succeeded in reducing Fe to a level suitable for fish culture. Fish culture experiments showed an absolute length growth rate of 0.09-0.18 cm/day and an absolute weight growth rate of 0.11-0.16 g/day. The feed conversion ratio was 1.18-1.40 and the survival rate was 98.04-99.08%. The survival rate of tilapia is high, the feed conversion ratio is medium and growth is low. The high environmental temperature and the decrease in water quality due to the absence of water changes and aeration are suspected of causing the low growth of fish. Therefore, further research with water change and aeration experiments and the use of other species of fish is needed to follow up the results of this study.

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.
