PENGARUH PEMBERIAN PAKAN ALAMI YANG BERBEDA TERHADAP SINTASAN DAN PERTUMBUHAN BENIH IKAN CUPANG (Betta sp.)

Abstract

Ornamental fish is a potential commodity because it has its own charm. One of the ornamental fish that currently has a lot of interest is Cupang fish (Betta sp.). Cupang fish at the seed stage really need good and quality feed to support success during cultivation. The purpose of this study was to analyze the effect of different natural feeds on the growth and survival of Cupang fish fry (Betta sp.) and to determine the best type of natural food for Cupang fish survival and growth. This study used a completely randomized design (RAL) with 3 treatments and 3 replications. Parameters observed were absolute weight growth, absolute length growth, specific growth rate, and survival rate. The results showed that different natural feeds had a significant effect on absolute weight growth, absolute length growth, and specific growth rates, while different natural feeds had no significant effect on Cupang seed survival. Furthermore, giving silkworms (Tubifex sp.) is the best natural food compared to water fleas (Moina sp.) and mosquito larvae (Culex sp.,) for the growth of Cupang fish seeds during maintenance.
