本文根据1984—1985年间在汾河水库采集的850尾H.leucisculus样品,对其年龄生长、食性、生殖和胚胎发育等进行研究。用Von.Bertalanffy生长公式描述了的该鱼生长特征。论述了这种鱼是以动物性食物为主的杂食性鱼类;摄食方式是主动捕食;其全面性成熟年龄,雄鱼为1龄,雌鱼为2龄;绝对怀卵量,据采集的标本为3766—2353粒;生殖期为6月下旬至8月上旬;产卵水温为24℃,卵呈粘性;孵化水温为24—25℃,时间为26.5小时;初孵仔鱼体长2.1—2.4毫米,体无色素,肌节41—43对。
Based on 850 samples of H.leucisculus collected in Fenhe Reservoir from 1984 to 1985, this paper studied the growth, feeding habits, reproduction and embryo development of this species. The fish growth characteristics were described by the Von.Bertalanffy growth formula. The article discusses that this kind of fish is a omnivorous fish mainly animal food. The feeding mode is active predation. The full maturity age of the fish is 1 year old and 2 years old female. According to the collected samples 3766-2353; Reproductive period is from late June to early August; The temperature of spawning water is 24 ℃ and the eggs are viscous; The incubation temperature is 24-25 ℃, the time is 26.5 hours; The length of newly hatched larvae is 2.1-2.4mm , Body pigment, sarcomere 41-43 pairs.
