Enhancing growth and survival rate of Asian Redtail Catfish Hemibagrus nemurus (Valenciennes 1840) Larvae through MinaPro probiotic soaking

Year: 2025
Type: article
Abstract: Asian redtail catfish (Hemibagrus nemurus) is a freshwater fish commodity with high economic value. However, the growth of the catfish larvae into fry is relatively slow. The administration of probiotics as a solution can increase the growth of fish larvae. Therefore, this research aimed to analyze the use of probiotics with a larval immersion method on the growth and survival of Asian redtail catfish larvae. A completely randomized design was adopted with four treatments and three replicates. Immersion treatment using probiotics consisted of P0 (control treatment without probiotic immersion), P1 (immersion treatment with a dose of 2.0 ml.L-1 of water), P2 (immersion treatment with a dose of 4.0 ml.L-1 of water), and P3 (immersion treatment with a dose of 6.0 ml.L-1 of water), with a stocking density of 50 fish/aquarium. The immersion was carried out every 10 days for 10 minutes in a basin container using 1 liter of water according to the specified dose. The results showed that the immersion larvae in probiotics significantly affected the biometric growth and survival (p<0.05). The highest biometric growth and survival was in P3- the group of immersion treatment with a dose of 6.0 ml.L-1 of water. This obtained absolute weight, length, and specific growth of 7.04 g, 8.81 cm, and 11.37% per day, as well as cannibalism type A and B of 8.00% and 0.00%, with cannibalism index, normal mortality, survival rate of 8.00%, 3.33%, and 88.67%, respectively.
