一、前言浮游生物是鱼类生长发育过程,尤其是早期阶段赖以生存的基础,据记载,草鱼苗7～9毫米时主要依轮虫为食,10毫米以上才以溞类为主?做阌?—22毫米以浮游动物为食,24毫米后浮游植物明显增加,一直到30毫米转入以浮游植物为主的生活。为了探讨人为控制水域浮游生物的演替,并摸索经济有效大量增殖轮虫与藻类的方法,作了一些对比试验,结果显示初见成效。
First, the introduction of plankton is the process of fish growth and development, especially in the early stages of survival based on records, according to the records, grass carp fry 7 to 9 millimeters based mainly on rotifers for food, 10 mm above the main type of catfish? Do 阌? -22 mm to zooplankton feed, 24 mm after the phytoplankton significantly increased, up to 30 mm into the phytoplankton-based life. In order to explore the succession of artificially controlling the succession of plankton in water area and to explore the economical and effective method of multiplying rotifer and algae, some comparative experiments were made and the results showed initial success.
