Natural Feeding to Increase the Growth of Sangkuriang Catfish Fry (Clarias sp)

Abstract

Feed is a major problem in aquaculture because it requires relatively large costs so that it requires alternative food sources in increasing production. This study aims to analyze the use of natural feed to increase the growth of catfish seedlings Sangkuriang Clarias sp. The study was conducted at the Feed Laboratory of the Department of Fisheries, Bosowa University for 31 days with experimental methods and a Complete Randomized Design. Sangkuriang catfish seeds are 1 month old with an average weight of 1.02 – 1.04 g, raised in a 5-liter jar-shaped container, with a density of 40 heads/jar. Feeding in the form of Daphnia sp, mosquito larvae, and Tubifex sp ad libitum three times every day, namely morning, afternoon, and evening. The results showed that the highest specific growth rate was obtained in Tubifex sp feed seeds by 14.91%, the highest mortality was achieved in Daphnia sp feed seeds at 16.6% and the lowest mortality was achieved at Tubifex sp treatment at 10%. Water quality during maintenance still follows the hatchery requirements of catfish Sangkuriang Clarias sp. Natural feeding Tubifex sp is better to give as natural feed because it provides a better daily growth rate compared to Daphnia sp and Mosquito Larvae.
