摘　　要：本研究以典型的浅水草型湖泊滆湖为对象,通过对几种水草营养成份的分析,草食性鱼类对这几种水草摄食程度的比较,发现草鱼、团头鲂最喜食的水草为苦草、轮叶黑藻和菹草。为促进这些饲料水草的繁茂,在湖区进行了这三种水草不同方法的种植及合理利用技术的试验。根据所得结果,提出了苦草刈割间隔期以23天为宜;通过割草养鱼试验,提出了蓄草养鱼的配套技术措施,并对滆湖网围养鱼的发展提出建议。Lake Ge Hu situated in the southwestern part of Jiangsu Province is a typical shallow lake. The lake with an area of 137.82 square kilometers is rich in submerged plants. The nutritive composition of aquatic plants in the lake are analyzed. The degree of like feeding on several species of submerged plants by herbivorous fishes is tested. The results indicated that Vallisneria spiralis,Hydrilla verticillata and Potamogeton crispus are likely fed by grass carp and bream. In order to promote the flourishing of high quality for aquatic plants,different transplanting ways have been carried out in Lake Ge Hu. Based upon investigation on productivity of Vallisneria apiralis an interval of 23 days between the two mowings is suitable. The technical measures for fish culture in mowing are presented. This paper gives some suggestions on how to develop pen fish farming in the lake. enclosure.
