请哪位翻译高手把下面的中文翻译成英文，小弟十分感谢！！

为了分析巢湖的太湖新银鱼对资源的利用情况，于2007年8月、9月在4个采样点分别进行了调查，研究了太湖新银鱼的食物组成、同时还进行了寄生虫感染情况的调查，并结合历史资料分析了巢湖的太湖新银鱼产量变化的原因。结果表明：在8月份，桡足类是太湖新银鱼的主要食物，占食物个数组成比例的68.32±11.85%，其次是枝角类，占食物个数组成比例的27.77±10.11%，轮虫数量极少，仅仅占3.47±6.05%；在9月份，桡足类也是太湖新银鱼的主要食物，占食物个数组成比例的63.35±27.00%，其次是枝角类，占30.94±27.94%，轮虫仅占1.77±6.14%。分析认为，桡足类是巢湖的太湖新银鱼的主要食物，枝角类和轮虫是次要食物。为了分析巢湖的太湖新银鱼种群数量变化的原因，由历年鱼类渔获量统计资料表明，1989-2007年的19年间其渔获量维持在较低水平，平均为312±116 t，占总渔获量的3.80±1.47%，分析认为，近20年来其渔获量较低的主要原因是：富营养化加重导致环境中浮游动物数量减少，鲚鱼泛滥形成巨大食物竞争压力，这导致巢湖的太湖新银鱼以桡足类为主要食物，致使大量感染寄生虫使其生长减慢、怀卵量减少。

In order to analyse the Chaohu Lake Taihu new icefish the use of resources, in August 2007 and September in four sampling points respectively, conducted a survey to study the Taihu new icefish food composition, also a parasitic infection The survey, combined with historical data of the Chaohu Lake Taihu new icefish output change. The results showed that: In August, copepods in the Taihu Lake is the main food of new icefish, the number of food composition of the 68.32 ± 11.85%, followed by Chi Kok categories, the number of food composition of the 27.77 ± 10.11%, Rotifer number of very small, only accounting for 3.47 ± 6.05%; in September, copepods in the Taihu Lake is the main food of new icefish, the number of food composition of the 63.35 ± 27.00%, followed by Chi Kok category, accounting for 30.94 ± 27.94 percent, rotifer only 1.77 ± 6.14%. Analysis of that copepods in the Chaohu Lake Taihu is a major new sweet fish food, Cladocera and rotifer food is secondary. In order to analyse the Chaohu Lake Taihu new sweet fish populations of the reasons for the change, the fish catch from the calendar year statistics show that ,1989-2007 in 19 of their catches at a lower level, with an average of 312 ± 116 t, accounting for Total catch of 3.80 ± 1.47%, analysis, nearly 20 years to lower its catch is the main reason: increase the lead to eutrophication in the environment decrease in the number of zooplankton, fish Coilia nasus a tremendous proliferation of food competition, which led to Chaohu Lake Taihu the new icefish to copepods in the main food, causing a large number of parasites to slow down growth, with less eggs.
