영문 초록

The frozen raw fish diet used in Moist pellet (MP) mainly derived from most available fishes like sardine, mackerel, horse mackerel, anchovy and convenias. In this experiment, the quality of these fishes were compared. 9-week feeding trials were conducted to investigate the effect of dietary five frozen raw fishes as ingredients of FRFDs on growth and feed efficiency of flounder. Percent weight gain of flounder fed the MPs containing horse mackerel and convenias had highest and lowest value, respectively. And also, MPs containing horse mackerel produced significantly greater feed efficiency than MPs containing raw fish from convenias : MP with convenias produced significantly lowest feed efficiency in flounder. According to the growth results in flounder, MPs containing the horse mackerel and mackerel produced higher weight gain and feed efficiency; therfore, horse mackerel and mackerel revealed superior ingredients as FRFDs with high availability. However, the other fish species also produced no significantly reduced growth. Before we select a ingredient of FRRD just with a growth result, we should also consider the other aspects like a self-pollution problem from a FRFD; because extracts from anchovy and sardine normally polluted around aquaculture places, there fish species carefully should be used in aquaculture.
