溪口水库库周山地面积多,植被较好。水库集雨面积为2300平方公里,最高水位淹没面积为44.7平方公里,库容达3.7亿方。正常养殖面积44700亩;最大水深25米,平均10米左右。我们于1987——1988年对该库的水生生物分春、夏、秋、冬四季;上、中、下游定四个断(编号为Ⅰ—Ⅳ)采样分析,基本摸清了水库饵料生物资源状况,为水库的合理放养积累了资料。一、饵料生物状况 1、浮游植物:有6门32种(属),其中:硅藻门10种,占31.25％;绿藻门11种,占34.38％;蓝藻门5种,占15.62％;隐藻、裸藻、甲藻门均两种,各占6.25％。变形裸藻、虫蚀隐藻、红胞藻、衣藻、栅
Xikou Reservoir Week mountain area, vegetation is better. Rainfall area of 2300 square kilometers of reservoirs, the highest water level submerged area of 44.7 square kilometers, storage capacity of 370 million square. Normal breeding area of 44700 acres; maximum depth of 25 meters, an average of about 10 meters. We sampled and analyzed the aquatic life in spring, summer, autumn and winter in four seasons of the upper, middle and lower reaches of China (No.Ⅰ-Ⅳ) from 1987 to 1988, and found out basically that the aquatic biological resources The situation, for the rational stocking of the reservoir has accumulated information. First, the biological status of bait 1, phytoplankton: There are 6 32 species (genus), of which: 10 species of Bacillariophyta, accounting for 31.25%; 11 species of Chlorophyta, accounting for 34.38%; 5 kinds of cyanobacteria, accounting for 15.62% Cryptophyta, euglenophyta, phylum are two kinds of doors, each 6.25%.
