Growth of Cantang Hybrid Grouper Juvenile (Epinephelus fuscoguttatus x Epinephelus lanceolatus) with Different Feeding Frequency

Abstract

Grouper is one of the fish that is much sought after by the general public because grouper have high economic value and one of the exported fish products. The high demand for grouper to cause community develop hatcheries grouper. Appropriate feeding and efficiency very influential towards the process of optimal fish growth. One of the feeding management of frequently used IE frequency feeding. Feed frequency is influenced by several factors, namely age, type and the appetite of the fish itself. The purpose of this study is to see the number of frequency of feeding on seeds of hybrid grouper cantang best to promote growth and feed efficiency and to lower the value of the feed conversion. This study used a RCD. The results showed that the granting of different frequency-feed can increase the growth of specific daily on the seed of hybrid cantang grouper. The highest growth rate of treatment weight i.e. P2 of 4.2 %/day. The value of the efficiency of feed conversion ratio and best i.e. P1 of 67% and 1.55. Treatment of the P1 value is the SGR. efficiency of feed conversion ratio and the lowest i.e. respectively 3.3%/day. 46% and 2.26.
