Pengaruh Penambahan Tepung Testis Sapi Brahman (Bos indicus) dan Pakan Komersil dengan Dosis Berbeda terhadap Jantanisasi dan Kelangsungan Hidup Seleksi Larva Ikan Gurami (Osphronemus gouramy)

Abstract

Aquaculture are very dependent on the availability of feed in sufficient quantity and good quality to assist in the fish growth process. It is known that male gourami fish (Osphronemus gouramy) grow faster so that it can increase production from growing gourami fish. One of the aquaculture biotechnologies that has been widely developed and applied in increasing aquaculture production, especially fish through masculinization, is sex reversal. This method is carried out orally by adding Brahman cattle testicle flour (Bos indicus) to commercial feed at different doses. The aim of this research is to determine the dominant gender by using cow testicle meal for the Sex Reversal process in Gourami Fish (Osphronemus gouramy) and to determine the effect of the interaction between mixing commercial feed and cow testicle meal used on sex formation in gourami fish larvae (Osphronemus gouramy). This research includes making Brahman cattle testicle flour (Bos indicus), a Randomized Block Design (RAK) with two factorials, namely mixing beef testicle flour (T) with commercial feed in different quantities and feeding rates with different doses of 3%, 4%, 5% with 3 (three) repetitions. The results of feeding cow testicle flour had a very significant effect on the formation of male genitalia in gourami fish (Osphronemus gouramy) at a 5% confidence interval and the concentration treatment by providing commercial feed and the addition of cow testicle flour had a very significant effect on genital formation. males in gourami fish (Osphronemus gouramy). With the S2F1 feed test with a mixture of 6% cow testicle flour and 94% commercial feed with a feeding rate of 3%.
