异育银鲫,具有养殖周期短、食性广、生长快、适应环境能力强、营养丰富等特点。为探索异育银鲫池塘养殖高产技术,1994年,天津市水产技术推广站和宁河县水产技术推广站联合在宁河县天和渔场进行了养殖高产试验,试验结果,18亩水面平均亩产667公斤,其中异育银鲫净产492公斤,平均规格207.1克/尾,每亩获纯利3940元,投入产出比为1:1.88。主要技术措施叙述如下:
Allogynogenetic crucian carp has the characteristics of short breeding cycle, broad feeding, rapid growth, strong adaptability to the environment and rich nutrition. In order to explore high-yielding breeding technology of allogynogenetic crucian carp pond, in 1994, Tianjin Aquatic Technology Extension Station and Ninghe Aquatic Technology Extension Station jointly conducted high-yield aquaculture trial at Tianhe Fishing Ground in Ninghe County. The test results showed that the average mu Producing 667 kilograms, of which 492 kilograms of heterotrophic crucian carp net, the average size of 207.1 grams / tail, net profit 3940 yuan per mu, input-output ratio of 1: 1.88. The main technical measures are described as follows:
