Model for Developing Home Industry Tiger Grouper Hatchery Firms (Hsrt) in Bali: an Overview on Economic and Maricultural Perspective

The high demand to grouper seeds in domestic and International market had pushed the mass grouper seeds production in Gerokgak District, Bali. At the first research, there were gaps between the average actual hatchery productivity of Tiger grouper (Epinephelus fuscoguttatus) hatchery firms with the potentially achievable productivity. This research then aimed for improving the productivity by determination of economic efficiency and optimum inputs combination. The research utilized data which were collected with survey to 41 samples of hatchery firms in Gerokgak District.The result in dry season: the average technical efficiency was 0.88903; the price efficiency was 1,554; and the economic efficiency was 1,381. In wet season the average technical efficiency was 0,72055; the price efficiency was 6,469, and the economic efficiency 4,661. The optimum inputs combination in dry season was grouper eggs 750 thousands pieces; pellet 6,0 kg; artemia 40 cans; mysid shrimp 660 sacks; rotifer 61 sacks; and workers  5 men. In wet season was grouper eggs 500 thousands pieces; pellet 6,0 kg; artemia 21 cans; mysid shrimp 210 sacks; rotifer 46 sacks; and workers 3 men. These optimum inputs could make meaningful contributions toward rising productivity and profitability of the Tiger grouper hatchery firms. Besides that, close attention should be given to improving managerial ability of the farmers and to preparing adroit hatchery workers through education and training.
