Abstract

This research was conducted on April to May 2017 in the Hatchery of TIU (Technical Implementation Unit) of Aquaculture Department, Marine and Fishery Faculty, Riau University, Riau Province. The aimed of this study was to know the effect of different fish stocking density toward the growth performance and survival rate of the Siamese shark fry on the aquaponics system. The method was using the experimental method with five treatment levels and three repeating (fifteen treatment units). The treatments were 30 fries/tank of fish stocking density (P1); 40 fries/tank of fish stocking density (P2); 50 fries/tank of fish stocking density (P3); 60 fries/tank of fish stocking density (P4); and 70 fries/tank of fish stocking density (P5). The material was 750 fries of Siamese shark with the size around 5-7 cm and it was reared for 45 days long. The results shown that the best treatment was in 60 fries/tank of fishstocking density (P4) or equivalent with 240 fishes/m2, and its absolute weight growth was 4.81 gram, absolute length growth 3.62 cm, specific growth rate 3.44 %, food efficiency 86.21 %, fresh plant weight (FPW) was 30.64 gram. Treatment by using a different fish stocking density had the same survival rate for all treatmentsthat was 100%.

Abstract

This  research  was  conducted  from  7th   of  March  to  16th   April  2017  at Research Center and Ornamental Fish Aquaculture (BRBIH), Depok - West Java. The objective of the research was to investigate the best of krill meal in fish meal and to increase color qualit y and growth of albino tiger barb (Puntius tetrazona). The method used was experimental method with Completely Randomized Design, with 4 treatment and 3 replications, ie 0%, 10%, 20%, 30% respectively. The fish were reared in aquarium with size of 40 cm x 30 cm x 30 cm (15 liters of water) with  density  of  10  fish/aquaria.  Fish  was  fed  3  times  a  day by means  of  at satiation.  Color sampling was done at the beginning  and the end of the study, while for growth sampling was done in the beginning and then every 10 days. The results showed that 30% krill meal gave the best color quality effect with L* =56.53, C = 16.60, H = 79.83, and absolute growth weight 0.68 g, absolute growth length 1.02 cm, specific growth rate 2.13% respectively.
