(Koan Fish (ctenopharyngodon idela c.v) In Various Feeding Dosages

Abstract

The research aimed to know the effect of feeding amount daily of Koan Fish (Ctenopharyngodon idela c.v) sized  on 5-8   cm length, 2.5 g weight and strew population  on fish per I 000 cc of water. Floury  feeding contents  40.92 % of protein have been given twice  a day on 09.00  a.m and 17.00 p.m, with the same amount. Dosage adjustment  have been done once a week after weighing the fish. Box culture  used consist   of twelve  box (30 x 30 x 30 Cm) and strew in 20  fish  per box.  The experiment used is Randomized  Complete Design with  four(4) levels   of feeding( 3. 6. 9 and 12 % offish  weight)  as treatment in three replications. The data is then analyzed using Analysis of Variance (ANOVA) and Least Significant  Difference (LSD) for meant compirisons.   No dead fish incidence in  the experiment. The growth acceleration  of fish per day increased from 0.19  % to  1.23 % as the feeding level  increased  from 3 % - 12 % of fish weight per day. The maximum growth acceleration of fish per day was 1.23 % on 10.83  % offish  weight per day feeding level with  10.20 % of feeding efficiency. The optimum growth acceleration of 0.80  % ·have  been found on 5.74. % feeding level of fish weight per day, with  15.93 % of feeding efficiency
