Abstract
Tropical catfish (Hemibagrus nemurus) is a commodity freshwater fish with high economic value. Silk worms (Tubifex sp.) type of natural feed a much-loved fish and other freshwater animals. Often a problem occurs in fish hatcheries Tropical catfish effort are stiil high level of death on the fry. This study aims to determine the best composition of the silk worms a live and provide, there optimal growth and survival rate of tropical catfish fry. This research was to used it that five treatments and three replications, namely: worms silk live and provide P1 (0%:100%), P2 (25%:75%), P3 (50 %:50%), P4 (75%:25%.) and P5 (100%:0%), test fish used is tropical catfish fry with an average weight (0.0079 ± 0.0019 g) and length (8.96 ± 0.48 mm) of 2400 tails, stocked as many as 160 fish/aquarium or 10 individuals/liter. Feeding during culture to used it the method of feeding rate that is equal to 10% of the weight fish biomass (ad libitum), frequency of feeding as many as five times a day, long maintenance of seed for 21 days. The results showed that the survival of tropical catfish fry during the study ranged 83.33 ± 3.08 to 88.96 ± 3.08%. Growth in absolute weights ranged from 0.247 ± 0.02 to 0.378 ± 0.050 g and the absolute length growth ranged from 18.80 ± 2.83 to 22.72 ± 2.33 mm. The growth rate of the specific weight daily ranged from 16.74 ± 1.77 to 18.51 ± 0.59%. While a specific length of daily growth rate ranged from 5.64 ± 0.51 to 6.00 ± 0.27%. Then the amount of feed consumption of tropical catfish fry ranged from 1.02±0.04 to 2.03±0.48 g, and feed conversion values obtained ranged from 2.94 ± 0.35 to 8.69 ± 1.80.
