摘要
以蚂蟥Whitmania pigra为试验动物,在排除振动、底物影响的前提下,以黄原胶作为饲料底物,观察不同浓度精氨酸对蚂蟥的诱食效应。结果表明,0.3%精氨酸对蚂蟥有明显的诱食作用,与蚂蟥天然饲料螺蛳体液中精氨酸质量分数2.97 mg·g-1相接近。
The effects of the feed attractants on Whitmania pigra were studied. The average weight of Wh. pigra were 5.0 g. Arginine was selected as feed attractants, xanthan gum was selected as feed substrate. The times of Wh. pigra going into the inducing room were recorded. The water temperature was 22-25 ℃ during the whole experiment. Arginine that had better inducing effect was chosen to carry on in the gradient experiment. The results showed that the best inducing effect was found when the added amount of arginine was 0.3%, which was close to the arginine content of the natural body fluid of Wh. Pigra and Bellamya purificata, 2.97 mg · -1 g
