徐州市郊区池塘精养水面以鲢鱼为主的肥水鱼养殖类型占70%以上,历来采取传统放养鱼种方式,池塘水面有5—6个月的时间处于低载鱼量期,在这期间,郊区池塘好的肥源,得不到充分利用,直接影响着鱼产量产值。为此我们于1990年承担市水产局下达的“鲢鱼与罗非鱼套养”项目。在下淀乡刘湾第二水产养殖场进行试验。于当年9月25日干池,9亩试验塘总产鲜鱼10669.5公(?),平均亩产鲜鱼1185.5公斤,比1989年
In the suburbs of Xuzhou City, the intensive water surface of the pond is dominated by silver carp, which accounts for more than 70% of the total species. The traditional method of stocking fish species has been adopted. The water surface of the pond is 5-6 months in the low-load period. During this period Suburban ponds good source of fertilizer, can not be fully utilized, a direct impact on fish production value. To this end, we undertook the “Silver Carp and Tilapia Cultivation” project issued by the Municipal Fisheries Bureau in 1990. In the next rural Liu Bay second aquaculture farm experiment. On September 25 that year dry pool, 9 acres of trial pond fresh fish production 10669.5 (?), The average yield of fresh fish 1185.5 kg, compared with 1989
