ABSTRACT

The aims of this study was to get the raw material ofwater plants feed and the addition of probiotics that can improve the growth of gauramy fish. The method used is the method of complete randomized design experiment with three replications. The treatments that were tried are four kinds of fish feed (pellets) made from Azollamicrophylla (salviniales), Lemna sp, Hydrillaverticillata (algae) and the pellet without water plants and the addition of probiotics. The results showed the growth of fish fed the pellets without water plant together with pellets made from Lemna sp. and better than pellets made of Azollamicrophylla and Hydrillaverticillata. Absolute growth ranged from 4.55 to 10.499 g, the relative growth from 26.059 to 54.302%, the daily growth from 0.1635 to 0.377 g / day, feed efficiency 26.697 to 54.961% and a survival rate of 63.33 to 70%. Temperatures range from 26-29⁰C, pH 6,5 - 8 and ammonia 0.6200 -0.9931 ppm. The results of the measurement of temperature, pH and ammonia still fulfill the qualification of carp live.
