| 摘 要： | 本文报道了养殖条件下暗纹东方Tun的摄食行为和不同生长阶段食物组成的变化，肠道食物分析表明，除主食配合饲料外，同时也摄食一些天然饵料（底栖类及小杂鱼等）。其肠长与体长呈直线相关，回归方程为Y．2.85x-32.36(X为体长，Y为肠长，单位：mm，相关系数R^2=0.9987),肠长为体长的2.35-2.74倍。同时对其食性的相关问题进行了讨论。

| Abstract: | The feeding behavior and the variety of food composition in different stages of Takifugu obscurus in culture are reported in the paper. Analyzing the food in the intestines by vivisection indicated that the fish also prey on some natural food (benthon, small-scale fishes etc.) in addition to formulated food. The relationship between the length of intestine and the length of body is linear regression, and the regression equation is Y=2.85X-32.36(X:body length, Y:intestine length, unit:mm, R2=0.9987), and the length of intestine is 2.35-2.74 times as much as body length.The problems related to the food selectivity of Takifugu obscurus are also discussed. |
