Abstract

Tilapia (Oreochromis niloticus) is a type of aquaculture commodity that has high economic value. This research aims to know the effect of feeding of rice bran fermentation on feed raw material to the parameter digestibility and growth of tilapia. The used tilapia were sized 5.33 ± 0.00 g/fish with stocking density 15 fish/40 L (aquarium). Fish were fed three times daily in ad satiation. This study used three treatment with four replications, namely (A) commercial feed as control, (B) commercial feed with the addition of rice bran fermentation with Aspergillus niger, (C) commercial feed with the addition of rice bran without fermentation. The results showed that the feed (B) can improve nutrient digestibility and growth of tilapia with dry matter digestibility of 67,87 ± 2,44 %, protein digestibility of 85.04 ± 3.28 %, feed intake of 230 ± 4.08 g, final weight 11.81 ± 0.45 g, specific growth rate of 1.65 ± 0.40 % and survival rate of 75.00 ± 0.11 % compared to the other treatments

Abstract

Golden snail contains high protein and carotenoids. Red melon discus fish requires high protein for growth and can be used for enhancing color. The purpose of this study was to evaluate the use of golden snail as a substitution of silkworms to increase growth and stimulate the color of red melon discus fish. The experiment used Completely Randomized Design (CRD) with 5 treatments and 3 replications. The treatments are 100% silk worm (A), 75% silkworm + 25% golden snail (B), 50% silkworm + 50% golden snail (C), 25% silkworm + 75% golden snail (D), and 100% golden snail (E). After acclimated, red melon discus fish of 0.32 ± 0.16 g and 2.41±0.02 cm in average weight and length were randomly stocked in 15 aquaria of 40x30x35 cm3 in dimension size containing 30 L water at 10 fingerlings/aquarium and given feed test as much as 5% body weight with frequency of 2 times a day for 56 days of the experimental period. The parameters that observed is survival rate, absolute weight, absolute growth, feed consumption and color. The results showed that high level of golden snail caused declining growth performance of red melon discus fish (P<0.05) and does not affect the color of discus fish (P>0.05) but can improve color quality during the experimental period. Substitution of golden snail to silkworm as much as 25% resulted in the highest growth performance and stimulate color of red melon discus fish.
