摘要
水温１５～２０℃时，条纹石鱼旨各消化器官的重量占鱼体重的百分比大小依次排列为比肝重＞比胃重＞比肠重，而在２５～３０℃时则排列为比胃重＞比肝重＞比肠重；水温１５～３０℃时，随着温度的上升，单位体重中酶蛋白所占的比例呈下降趋势；１５～２０℃时，消化道蛋白酶的活性随着水温的升高而显著增大，超过２０℃时，蛋白酶的活性又呈下降趋势；１５～２０℃时，各消化器官中蛋白酶的比活均上升９倍，２０～３０℃时，肝蛋白酶的比活继续增大，而胃及肠蛋白酶的比活则略有下降。
Under the water temperature of 15～20℃, the weight of striped bass digestive organs in percentage of body weight is in the sequence of liver weight ratio > stomach weight ratio > intestine weight ratio, and the sequence changes to stomach weight ratio > liver weight ratio > intestine weight ratio when the water temperature in 25～30℃. Within a water temperature range of 15～30℃, the percentage of protein enzyme in per unit body weight tends to decrease with the increase of temperature. The activity of protein enzyme in digestive tracts significantly increases with the increase of water temperature when the temperatrue in 15～20℃ and the activity tends to decrease when the temperature is over 20℃. The activity ratio of protein enzyme in digestive organs increases 9 times when the temperature is 15～20℃; the activity ratio of protein enzyme in liver continues to increase when the temperature is 20～30℃, but those in stomach and intestine decrease a little.
