在水库渔业生产中,鱼种的合理放养,是直接关系到合理利用饵料、水体空间和时间,取得高产高效益的关键,也是水库渔业最重要的技术环节,这对于精养水库来说,尤为重要。精养水库具有不同于粗养水库的特点和要求,因此,其鱼种放养计划的制订要比粗养水库难度大,目前我国还缺乏这方面的经验。为了探讨这方面问题,笔者根据对一些精养水库研究体会,试以可供给的饲料、肥料为前提,浅谈制订精养水库鱼种放养的思路和方法,与同行共同研究这一问题。
In the reservoir fishery production, the rational stocking of fish species is directly related to the rational use of food, water space and time, to achieve the key to high yield and efficiency, but also the most important technical aspects of reservoir fisheries, which intensive reservoirs, especially important. The intensive reservoirs have different characteristics and requirements from those of the crude reservoirs. Therefore, it is more difficult to plan their stocking plan than that of the crude reservoirs. At present, China still lacks experience in this field. In order to explore this aspect, the author based on the study of some intensive reservoirs experience, try feed available, fertilizer as a precondition to talk about formulating ideas and methods of intensive stocking of fish species, and their counterparts to jointly study this issue.
