近年来,吉林省淡水养鱼事业发展迅速,成鱼生产不断增加,苗种生产相对减少。过去我省多从辽宁购入苗种,近几年由于辽宁的饲料价格与我省基本持平,加之辽宁养鱼户亦增加,我省从辽宁购入苗种减少。而黑龙江、内蒙等地随养殖生产日益增加,从我省购出大量苗种。基于上述原因,造成我省苗种短缺。为解决该问题,我们于1990年在吉林省农安县2814渔场,利用成鱼池前期生产夏花鱼种,经试验取得满意效果,现报告如下。
In recent years, the rapid development of freshwater aquaculture in Jilin Province, adult fish production increased, the relative reduction of seed production. In the past, our province purchased more seedlings from Liaoning. In recent years, due to the fact that the feed prices in Liaoning are basically the same as those in our province, and the number of fish farmers in Liaoning is also increasing, the purchasing of seedlings from Liaoning Province has been reduced. The Heilongjiang, Inner Mongolia and other places with the growing production of breeding, buy a large number of seedlings from our province. For the above reasons, causing shortage of seedlings in our province. In order to solve this problem, we used the pre-production summer flower species in the adult fish pond in Nong’an County, Jilin Province, in 1990, to obtain satisfactory results through experiments. The report is as follows.
