Background
The siganids belong to Perciformes (Perciformes), Siganidae (Siganidae), siganimus (Siganus), commonly called Murray, and more than twenty kinds, and the siganids are mainly cultured in China. The bluefish is fond of inhabiting at the river-sea junction of rocky rock, coral plexus and mangrove swamp, and is more accustomed to group activities, inhabitation and foraging. Due to the feeding impurity, the algae and attachments in the pond can be ingested, the function of cleaning water is achieved, and the economic value is high. The siganus oramin belongs to wide-salinity fish, and the preferable growth salinity of the siganus oramin is about 22 per mill, which is similar to the growth conditions of marsupenaeus japonicus. The siganus oramin is suitable for polyculture, and the success rate of polyculture of siganus oramin is higher than that of monoculture.
Grouper belongs to warm water-based, wide-salinity, large and medium-sized carnivorous fishes, and is a rare variety which is cultured by using a fishpond or a net cage near seaside in south China. The grouper is a high-grade marine product with high protein and low fat, and is also a delicacy for people on festive banquet, and the like. Because the current domestic culture areas are few, the culture area is small, the traditional culture method is laggard, the supply of the provided product is short of demand, the domestic market needs can not be met, the cement pond culture is also started to be changed into the single-variety culture, the grouper has the habit of not eating the bottom-sinking feed, the bottom-sinking feed not only causes the waste of the feed, but also causes the higher feed coefficient and the increased cost, and the residual feed can cause water pollution and influence the culture environment.
