1988年以来,任丘市鱼种场依靠科技进步,实施综合技术,利用一口13亩陈旧坑塘,探索池塘育种高产高效生产新途径,连续5年增产增收。5年合计总产鱼种8.04万千克,亩产1237千克。其中鲤鱼鱼种5.95万千克,亩产915.4千克,平均规格80.5克。鲢、鳙鱼种2.09万千克,亩产321.5千克,平均规格63.9克。比施用常规技术增产11.7万千克,年增产2.13万千克,增产率为231%。技术效益10.75万元。该技术在河北省已大面积推广应用,并取得显著经济效益。现将育种配套技术介绍如下。
Since 1988, Renqiu City fish breeding market rely on scientific and technological progress, the implementation of integrated technology, the use of a 13 acres of old pit ponds to explore new ways of breeding high yield and efficient production of ponds, increase production for five consecutive years. Total 5 years total production of 80,400 kilograms of fish species, 1237 kg per mu. Carp fish species which 59,500 kg, 915.4 kg per mu, the average size of 80.5 grams. Silver carp, bighead carp species 20,900 kilograms, 321.5 kilograms per mu, the average size of 63.9 grams. Than the use of conventional technology to increase production of 117,000 kg, an increase of 21,300 kilograms, an increase of 231%. Technical benefits 107,500 yuan. The technology has been widely applied in Hebei Province, and achieved significant economic benefits. Breeding technology now is as follows.
