饵料种类对中间球海胆的品质有显著影响。长期摄食鲜海带或裙带菜的海胆生殖腺呈橘红色和橘黄色,摄食孔石莼为浅橘红色和橘黄色,摄食人工配合饲料为土黄色和乳白色。长期摄食鲜海藻类的海胆生殖腺味道甜美,口感上佳;而摄食人工配合饲料的则有苦涩味。饵料种类及其交替方式决定了海胆生殖腺色泽和口感的转变速度,其中鲜海藻类间转换速度基本一致,均需60d可完成;而人工配合饲料则需80d方能完成。中间球海胆消化道的颜色更易受饵料种类的影响,其转换速度与饵料种类和交替方式无关,20d即有明显表现,40d可完成。
The type of diet has a significant effect on the quality of the midgut urchin. The long-term consumption of fresh seaweed or wakame sea urchin gonads were orange and orange, feeding stone bream for the light orange and orange, feed artificial feed for the khaki and milky white. Long-term consumption of fresh seaweed genital gland sea urchin taste sweet, good taste; and feeding artificial feed is bitter astringency. The species of bait and its alternation determine the transition speed of sea urchin gonad’s color and taste. Among them, the conversion rates of fresh seaweed are basically the same, both of which need to be completed 60 days; while the artificial feed needs 80 days to complete. The color of the midgut sea urchin digestive tract is more likely to be affected by the type of food, and its conversion rate has nothing to do with the type of food and the alternate way, 20d obvious performance, can be completed 40d.
