摘要
为贵州山区规模化生产台湾泥鳅种苗提供科学依据,2015-2016年采用人工催产技术对规格为17～19尾/kg和12～14尾/kg的雌亲鳅505.5 kg进行了人工繁殖研究.结果表明:2015年繁育台湾泥鳅种苗4批共840万尾,平均受精率70.25％,孵化率73％,种苗成活57％;2016年繁育种苗5批共1 640万尾,平均受精率93.40％,孵化率96.8％,种苗成活70％;2年共繁育泥鳅种苗2 480万尾,实现种苗销售产值224万元,利润89.6万元.在一定的亲鳅标准(8～10尾/kg)、科学合理的孵化设施(一槽一系统)以及育苗池(单池面积1 200～1 300 m2,池深1.4～1.5 m,水位保持1.2～1.3 m)条件下,贵州山区能较好地对台湾泥鳅种苗进行规模化人工繁殖,并取得良好的经济效益.
Abstract
To provide the scientific basis for scale production of Taiwan loach hatchlings in Guizhou mountainous area,the technique of artificial oxytocin was used on Taiwan loach of 505.5 kg (1kg for 17～19 fish or 12～14 fish) artificial breeding from 2015 to 2016.Results:In 2015,the fry breeding of 8.4 million (4 batches),the average fertility rate of 70.25％,the hatching rate of 73％,the average survival rate of 57％;In 2016,the fry breeding of 16.4 million (5 batches),the average fertility rate of 93.4％,the hatching rate of 96.8％,the average survival rate of 70％.The total fry breeding was 24.8 million in the two years.The sales value was 2.24 million Yuan,and profit was 0.896 million Yuan.Under conditions of definite standard(8～10 fish/kg),scientific hatching equipments(one-for-one system) and nursery pond (area 1 200～ 1 300 m2,depth 1.4～1.5 m,water level 1.2～1.3 m),artificial scale breeding of Taiwan loach could be preferably conducted in Guizhou mountainous area,and good economic benefits could be achieved as well.
