摘要
磷是淡水水体富营养化的限制因子,养殖水体磷污染主要来源于饲料。提高饲料磷的利用效率是降低水产养殖过程磷排放的最重要的措施,但其前提条件是需要摸清鱼类对磷的吸收代谢规律。本文综合现有文献,阐述了鱼类对饲料磷的吸收特点、转运机理和代谢机制等方面的研究进展与成果,旨在为国内低磷饲料的研究和生产应用提供科学指导。
Phosphorus is the key limited factor for water eutrophication.In aquatic water bodies , phosphorus mainly comes from fish feed.The most important way to reduce aquatic phosphorus waste is to improve the utilization efficiency of dietary phosphorus in aquaculture.In order to improve dietary phosphorus utilization , we need to know the absorptive and metabol-ic mechanism of dietary phosphorus in fish.The current review stated the absorption , transportation and metabolism of diet-ary phosphorus and the relating effected factors in fish.The purpose of this review is to provide basic knowledge for impro-ving dietary phosphorus utilization and reducing phosphorus waste in aquaculture water bodies .
