Enrichment of feed for growth of cantang grouper (E. fuscoguttatus x E. lanceolatus) in floating cages

Research output: Contribution to journalConference articlepeer-review


Grouper (Epinephelus sp.) is one of the superior species in the development of marine culture in Indonesia which has high economic value and has become an export commodity. One of the factors that influence production results in aquaculture is feed. Good quality of feed is crucial for fish survival and growth. Therefore, the feed given to cultured fish must be able to meet all the nutrients needed. One way that can be used to improve nutrition in feed is enrichment. This study aims to determine the enrichment of feed on the growth of cantang grouper by addition multivitamins to the feed. Cantang grouper reared in two floating net cages; one is given artificial feed without enrichment and the other one with multivitamin enrichment. The multivitamin dose for enrichment is 0.3%. Sampling was carried out by measuring the weight and length of 10 fishes every seven days from each floating net cage. The growth of cantang grouper which was given a multivitamin enrichment in the feed showed a growth rate 2.53 grams/day, length of growth 0.055 cm/day, feed efficiency was 29.4% higher and FCR was 3.4 lower compared to the grouper without enriched feed.
