Abstract

The provision for the cultivation Asian redtail catfish fry needs is still limited, because adhesion of the eggs is strong. The solutions for this problem is to immersion of the eggs using natural plant extracts which are easy to obtain and cheap. The aim of of this research was to assess the impact of different natural plant extract on the adhesion on eggs of Asian redtail catfish fry. The study was carried out at the Fish Hatchery and Breeding Laboratory, Riau University from June to July 2023. The design used was a completely randomized design, with various natural plant extracts: P0 (control), P1 (1.00 ml pineapple solution per liter of water), P2 (4.00 bilimbi solution per liter of water), and P3 (4.00 ml Jamaican cherry leaves solution per liter of water). The results showed that the best treatment was observed in P3, resulting in a fertilization rate of 90.40%, hatching rate 87.13%, egg adhesion rate of 14.28, absolute weight growth of 1.2611 g, absolute length growth of 5.54 cm, daily weight growth of 13.17% per day, and a survival rate of 83.52%.
