| dc.description.abstract | Botia (Chromobotia macracanthus) is a freshwater fish that are having
economic value is important because it has high sale value, especially in the
ornamental fish market in North Sumatra. Life food is an important factor in the
cultivation of ornamental fish. The research was conducted to determine the effect of
feeding Tubifex worms (Tubifex sp.) on the growth performance and survival rate of
Botia larvae. Tubifex worm culture do by using a wooden box with a recirculation
system and the maintenance of Botia larvae done with volume 72 liter aquarium in a
closed room.
Experimental design using a completely randomized design with 5 treatments
with 3 replications, as follows; 1) The Tubifex worms culture given chicken manure
fermentation, 2) The Tubifex worms culture given cow manure fermentation, 3) The
Tubifex worms culture given sheep dung fermentation, 4) Tubifex without treatment,
5) Pellet ornamental fish. The survival rate was 100 % in each treatments. Feeding the
Tubifex worms are cultured with sheep dung fermentation gives the best results on the
survival rate (SR), the absolute length (L), absolute weight (W), and daily growth rate
(GR), respectively 1.02 cm, 0.91 g, and 2.57% for 30 days of maintenance. | en_US |
