Abstract

This research was performed to determine the effect of turmeric liquid immersion in artificial feed on growth, survival, feed efficiency and profit in the cultivation of TGGG (♀ tiger grouper × ♂ giant grouper) hybrid grouper. The test fish had an average size of 46.46±3.21g given 3 different feed treatments, namely: feed immersion using turmeric liquid with a dose of 0.5% (treatment A), 1.0% (treatment B), and 1.5% (treatment C). The results of this research proved that with the right dose, turmeric can improve the performance of the TGGG hybrid grouper cultivation business by increasing the fish growth (WGR and SGR), feed efficiency (FCR), and BC ratio. Treatment C showed the most optimal performance at turmeric doses of 1.7% for FCR, 1.8% for BC ratio, 2.4% for SGR and 2.6% for WGR.
