摘要：Milkfish Chanos chanos is an important fisheries commodity with high economic value. Demand on this species increased year by year either as local consumption, bait for tuna catching, candidate of broodstock, or for fulfill of export demand. An experiment to evaluate the the effect of implantation LHRH-a hormone on spawning profile of milkfish generation-1 broodstock was conducted in Institute for Mariculture Research and Fisheries Extension, Gondol, Bali. Fifty fish (with average total length of 78.04±2.80 cm and body weight of 5.80±0.45 kg) were implanted with LHRA-a hormone at dosage of 50 µg/kg fish (Tank A). Another 50 fish with the same size without LHRA-ά hormone treatment were used as control (Tank B). The result showed that both of fish groups spawned and produced the eggs. But, the number of eggs produced by fish treated with LHRA-a hormone much higher than control. Quality of eggs produced by fish treated with LHRA-a hormone was also better than control. Fish treated with LHRA-a hormone spawned 26 times with total eggs of 5,911,200. In control group, the fish spawned 14 times with total eggs of 2,720,410. Hatching rates of treated fish ranged from 60.20- 85.20% compared with 50.0-74.50% in control fish. Survival activity index (SAI) was 3-5 days in treated fish and 2-4 days in control fish. The concluded results of the study of hormones in the milkfish broodstock has increased the spawning profile and the number of eggs produced.
