摘要
本文通过对徐家河水库陆封近太湖新银鱼周年生长的研究，揭示其生长的规律性，并根据其生长特性和生活习性，结合水库的生态特点，确定徐家河水库近太湖新银鱼的合理捕捞时间，提出促进水库近太湖新银鱼生长，提高其生产量的措施。
The growth charactalstics of Neosalanx pseudotaihuensis Zhang in Xujiahe Reservoir were studied. The results show that:1. The rehaonship between body weight,W(g) and body length, L(mm) can been expressed as W = 2. 014 × 10-6L3.170(r= 0. 999).2. The relationship between month age, T and length L, and weight W can be expressed as:3. The growth inflection point is at tr =4.3 months, corresponding to W=0.34 g. Based on the growth characteristies, living habits of the fish, and the ecological character of the reservoir, the fishing period of the icefish is suggested from the end of September to the middle of November.4. The measures of promoting icefish growth and increasing its yield through applying inorganic fertilizer or swine-fish integrated farming in Xujiahe Reservoir are proposed.
