Effect of Premix in Different Levels on the Feeding and Growth of Turbot (Scophthalmus maximus)
A feeding trial was conducted to investigate the different diets on the feeding and growth of turbot (Scophthalmus maximus). Three experimental diets included the same copmpositions except the levels of premix,dietl 16 mg/g,diet2 20 mg/g,diet3 24 mg/g . The control diet was high quality imported feed EP4. Each diet was randomly assigned to 3 samples of 100 fish per aquarium (initial weight (51. 00± 1. 07) g). Fish were maintained at water temperature ranging from 13. 0 to 14. 0 ℃ , water salinity ranging from 25—28 mg/g. Fish were fed twice daily for 30 days. There is no significantly different on feeding rate, weight gain and specific growth rate among the different diets. The growth performance of experimental diets has reached the level of high quality imported feed. The feed conversion of D2 is lower than D1 and D3, the protein efficiency of D2 is higher than D1 and D3, but there are no significantly different. The results indicate the wide range of the turbot on premix. The 20 mg/g levels of premix is appropriate to experimental feed of the turbot.
