Feeding habit is one of the most important reference bases for making feeding strategy in fish aquaculture. During the fish seedling culture stage, the feeding amount, feeding species and feeding time which fit the fish feeding habits well will not only increase the survival rate but also improve the feed efficiency greatly. The Sebastes schlegelii is one of the most important aquaculture and enhancement fish species in China, Japan and Korea. In culture conditions, though the feeding cost is the greatest production cost during the S. schlegelii seedling culture, an excessive mortality still often occurred during the early development culturing stage due to inappropriate feeding strategy. Therefore, in order to better understand the feeding characteristics of S. schlegelii during the early development stage, the feeding habits of larvae and the gastric evacuation rate of juvenile in the condition of artificial seedling were examined by using an experimental ecology approach. Results show that S. schlegelii had already acquired good foraging capability at larvae stage. For the feeding rhythm of 2 days after hatch (DAH), S. schlegelii larvae exhibited feeding peak at 16:00, and the feeding peak of post-larvae (15 DAH and 25 DAH) was at 16:00 and 20:00. So the feeding behavior of S. schlegelii larvae mainly appeared at daytime and the feeding peak period was gradually prolonged with fish growth. The daily feeding intake rates of larvae S. schlegelii were 42.26% (2 DAH), 16.25% (15 DAH) and 13.07% (25 DAH), which could be used as a reference for daily feeding of larvae in seedling culture. The results show that juvenile S. schlegelii with different body weight (average body weight 1.78 and 8.52 g) exhibited different gastric evacuation traits at 22℃. The linear, exponential, square root and Logistic models were used to fit the gastric evacuation data and all the four models fit the data well. After a composite analysis, it can be concluded that the best mathematical model fitted to the gastric evacuation data of 1.78 and 8.52 g juveniles were the linear model and the Logistic model respectively. Through the mathematical model, it can be calculated that the gastric evacuation rate of 1.78 and 8.52 g juvenile S. schlegelii were 0.007 and 0.047 g/h respectively. Based on the gastric evacuation traits and the effect of feeding frequency on the coefficient of variation of fish body weight, it can be concluded that feeding to satiation twice or thrice per day is appropriate for 60-90 DAH juvenile S. schlegelii in the rearing practices.
