为了解淡水鲳主要养殖生物学特性及其池塘养殖技术,我们在1986年试养的基础上,于1987～1989连续三年进行了池塘养殖技术研究。一、材料与方法试验用鱼池是本所菱湖工作站土池。1987年是4号池,面积396米~2,平均水深1.3米;1988年为1号池,面积333米~2,水深1.2米;1989年为5号池,面积333米~2,水深1.2米。放养前池水排干,用生石灰或漂白粉清塘。 1987年和1988年的试验用鱼种购自外省。1989年是本所上年人工繁殖的越冬鱼种。淡水鲳三年放养情况见表1。鱼种放养后用0.1ppm呋喃唑酮全池泼洒,以防感染。为
In order to understand the main biological characteristics of freshwater pomfret breeding and its pond culture technology, we conducted the pond culture technology research in 1987 and 1989 for three consecutive years on the basis of trial cultivation in 1986. First, the materials and methods of test fish pond is our library Linghu workstation soil pool. 1987 is a pool 4, an area of 396 meters ~ 2, an average depth of 1.3 meters; 1988 for the pool 1, an area of 333 meters ~ 2, water depth of 1.2 meters; 1989, No. 5 pool, an area of 333 m ~ Meter. Reserve water before draining the pond, with quick lime or bleach Qing Tong. Experimental fish species purchased in 1987 and 1988 from other provinces. 1989 is the year of artificial breeding overwintering fish species. Tamshui 鲳 three years stocking situation shown in Table 1. Fish stocking with 0.1ppm furazolidone Quanchiposa to prevent infection. for
