Pemanfaatan Hidrolisat Protein Kepala Udang sebagai Atraktan pada Pakan Pasta Larva Ikan Baung (Hemibagrus nemurus)

The operation of a fish hatchery business cannot be separated from various factors, such as the need for feed, a complete nutritional diet, the feed that should always be available, the size of the feed based on the mouth opening, easy to digest, and affordable with the aim that it will be able to cost-cut. The feed often used for fish larvae is silkworms (Tubifex sp.), but the price is relatively expensive, and its availability is limited; hence it is unprofitable for fish farmers. One alternative to replacing Tubifex sp. as feed for fish larvae is artificial feed. However, the use of artificial feed is less effective due to its low attractiveness to fish, which leads to slower growth in the fish larvae. The solution that can be done to overcome this problem is through supplementation of shrimp head protein hydrolysate (SHPH) attractants in the feed. With the presence of attractants in the feed, it is expected that the response of fish larvae to the feed will increase so that their growth will be optimum.
The objective of this study was to assess the effect of supplementation of SHPH attractants in feed and the optimal inclusion percentage to increase palatability, first feed response of fish larvae, feed rejection, no feed response, protease enzyme activity, specific growth rate, feed consumption, survival, and proximate body composition of Asian redtail catfish (Hemibagrus nemurus) larvae. The study utilized a completely randomized design with four treatments and
three replications: SHPH attractants supplementation in feed with the inclusion levels of 0%, 2.5%, 5%, and 7.5%, respectively. The Asian redtail catfish larvae used were three days old with an average weight of 0.01 ± 0.00 g, and the study lasted for 30 days. The parameters observed were palatability index, speed of first feed response, feed rejection, no feed response, protease enzyme activity, specific growth rate, feed consumption, survival, proximate body composition, and water quality of rearingmedia (temperature, pH, DO, and ammonia). Data were analyzed using SPSS version 24. The differences among treatments were analyzed using one-way Analysis of Variance (ANOVA) and the significant mean differences were compared using Duncan's test at a 95% confidence level.
The results showed that the supplementation of SHPH attractants in feed had a significant effect on palatability, speed of first feed response, feed rejection, no feed response, protease enzyme activity, specific growth rate, feed consumption, and survival of the larvae (p < 0.05). The optimal inclusion level of SHPH attractants for Asian redtail catfish larvae feed is 5%. At this level, the feed palatability was 20.64%, the first feed response speed was 5.20 seconds, feed rejection was 1.11 %, no feed response was 0.45%, protease enzyme activity was 0.07 IU/mL, specific growth rate was 9.83%/ day, feed consumption was 61.38 g, the survival rate was 73.11%, and the proximate composition of the body of Asian redtail catfish larvae, such as moisture, ash, protein, fat, crude fiber, and NFE, were 78.04%, 2.45%, 13.31%, 4.34%, 0.30%, and 1.58%, respectively. From the findings of the study, it can be concluded that supplementation of SHPH attractants in feed has been proven to be effective in increasing palatability, feed consumption, growth, and survival of Asian redtail catfish larvae with an optimal inclusion levelof 5%. Theseresults suggest thatthe useof SHPHattractant can be an efficient and sustainable solution in catfish cultivation, moreover overcoming the obstacles faced in the use of conventional feed.
