摘要/Abstract

摘要： 2017年6月至2018年4月,在大渡河黑马鱼类增殖站进行了侧沟爬岩鳅（Beaufortia liui）的人工繁殖和胚胎发育初步研究。结果表明,侧沟爬岩鳅为底栖、杂食性鱼类,昼伏夜出。其繁殖季节为2—4月,成熟卵呈卵圆形,卵径约0.8 mm,淡黄色,微黏性。受精后约15 min卵膜吸水膨胀至最大,卵径约1.2 mm。在水温（17±0.5） ℃下历时60 h 55 min,积温974.56 ℃·h,经过7个阶段完成胚胎发育。仔鱼出膜6 d开口,出膜45 d,仔鱼的胸鳍和腹鳍完全特化,其体型与成鱼基本相同。

Abstract: From June 2017 to April 2018, Experiment of artificial reproduction embryo development of Beaufortia liui in the Dadu river black horse fish breeding station. The results showed that it was omnivorous fish and benthic like nocturnal. The breeding season was from February to April, the mature eggs were oval, the egg diameter was about 0.8 mm, and the yellowish, slightly sticky. About 8 minutes after fertilization, the egg membrane swelled to the maximum, and the egg diameter was about 1.2 mm. At a water temperature of （17±0.5） ℃ for 60 h 55 min, the accumulated temperature of 974.56 ℃·h. Embryo development was completed in seven stages. After 6 days, the seedlings began to eat. The pectoral and ventral fins of the larvae were completely specialized after 45 d of film emergence, and their body shape was basically the same as that of adult fish.
