最近几年池塘养殖业发展迅速,单产水平较高,总产递增较快,但生产效益却停滞不升反而下降,通俗讲就是养殖经济效益越来越差,不挣钱,利极微,严重挫伤了养殖户的积极性。针对这种情况我们在广泛调查了解的基础上进行了多项试验,并对试验结果进行了对比分析,得到一些粗浅体会,供同行参考。1.合理调整养殖品种结构对主要品种和配养品种的比例进行调整,生产操作中可适当减少主养品种和常规配养品种的数量,增加部分优良品种作配养
In recent years, the rapid development of pond aquaculture, high yield level, the total output increased rapidly, but the production efficiency has stagnated but declined, popular saying is that the economic benefits of farming is getting worse, not making money, the profits are minimal, serious Dampen the enthusiasm of farmers. In response to this situation we conducted a number of tests based on extensive investigation and understanding, and conducted comparative analysis of the test results to get some superficial experience for peer reference. 1. Reasonable adjustment of the structure of cultured varieties of the main species and the proportion of varieties to be adjusted, the production operation may be appropriate to reduce the number of varieties and conventional varieties, increase some of the fine varieties for cultivation
