Abstract
The effects of feeding frequency on growth, food consumption, body composition, and blood chemistry of dark-banded rockfish, Sebastes inermis, were investigated for 70 d. A total of 30 rockfish each (initial mean body weight of 13.7 +/- 0.1 g) were randomly distributed to twelve 75-L tanks. Fish were hand-fed to satiation with a commercial diet (51.0% protein) under one of four different feeding frequency treatments (one, two, or three meals per day or one meal for 2 d). At the end of the experiment, fish fed with two and three meals per day exhibited the highest weight gain, specific growth, and feeding rates. Feed efficiency and size variation were not significantly affected by feeding frequency (P > 0.05). The maximum food consumption occurred during the last meal (1700 h) of the two and three meals per day treatments. As feeding frequency increased, whole-body protein and lipid, as well as plasma total cholesterol and high-density lipoprotein cholesterol contents also significantly increased (P < 0.05). We concluded that the juvenile dark-banded rockfish weighing from 10 to 40 g can achieve the best growth performance when they are fed two meals per day under our experimental conditions.
