| 中文摘要: |
| 研究了强壮藻钩虾Ampithoe valida的食性及其对温度、盐度变化的响应。研究结果表明，1）强壮藻钩虾消化道内含物组成主要可分为有机物碎屑和大型藻类。2）强壮藻钩虾消化道中蛋白酶活力最高，脂肪酶活力次之，淀粉酶活力最低。3）使用不同饵料（对虾人工配合饲料、硬毛藻、小球藻、生物絮团和蛤蜊肉）饲养强壮藻钩虾，发现对虾人工配合饲料为其生长的最佳饵料。4）成体强壮藻钩虾比幼体强壮藻钩虾耐高温，且耐温能力与其生活水温有关，生活水温相对较高情况下耐温能力也相应提高。5）强壮藻钩虾为广盐种，在盐度4～40范围内均可正常存活。 |
| 英文摘要: |
| In this study, the feeding habits of Ampithoe valida were analyzed, and its response to different temperature and salinity were observed. It was found that (1) the contents of the digestive tract of A. valida were classified into organic debris and algae;(2) Among the digestive enzymes in the digestive tract of A. valida, the activity of trypsin was the highest, followed by LPS, which was higher than AMS; (3) More rapid growth was achieved when A. valida fed on shrimp pellet diet, compared with diets such as Chaetomorpha antennina, Chlorella,bioflocculant(biofloc) and clam meat diets; (4) Adult A. valida showed greater ability for high temperature resistance than young ones, and this tolerance is related to their living water temperature; (5) A. valida is a euryhaline animal, which can survive a salinity in the range of 4~40. |
