采集钱塘江野生粗唇,在人工池塘环境下培育至性成熟,平均培育成熟率64.4%。经测定其平均绝对怀卵量为7200粒/尾,平均相对怀卵量为49.9粒/g体重。采用DOM、HCG、LRH-A2混合催产剂,分两次注射,在25℃至28℃水温下,分3批次进行了人工繁殖,共催产亲鱼114组,效应时间为17h至20h,平均催产率83.8%,平均孵化率63.5%,共获得鱼苗26.0万尾,平均出苗率81.5%;共获得夏花鱼种17.8万尾,平均培育成活率68.5%。
Wild Qiongtang crude lip gulp was collected and cultivated to sexual maturity under the artificial pond environment, with an average maturity of 64.4%. The average absolute fecundity was 7200 / tail and the average relative fecundity was 49.9 / g body weight. Inoculation of DOM, HCG and LRH-A2 mixed oxytocin was carried out in two batches and artificial propagation was conducted in three batches at 25 ℃ to 28 ℃. Total of 114 fish broodstocks were induced and the effect time was 17h to 20h. The mean oxytocin Rate of 83.8% and average hatching rate of 63.5%. A total of 260,000 fry were obtained, with an average germination rate of 81.5%. A total of 178,000 species of summer flowers were obtained, with an average breeding survival rate of 68.5%.
