摘要: 在平均水温分别为14.2、15.6、16.5、23.4和24.5℃时,寡齿新银鱼胚胎孵化时数依次为142、119、108、68和61h.胚胎发育时序可分为10期.温度与胚胎孵化时间呈幂函数关系,H=6861.1988×T-1.4717;积温与胚胎孵化时间亦呈幂函数关系,H=1.6081×10-8×A3.0151.

Abstract: When average water temperature is 14.2, 15.6,16.5,23.4 and 24.5℃,the incubationtime of Neosalanx oligodontis is 142, 119,108,68 and 61 hours in turn.Its embryonic development can be divided into ten stages. The relationship between temperature and incubation time is expressed as H=6861.1988 T-1.4717,and that between accumulated temperature and incubation time is H=1.6081×10-8A3.0151.

Key words: Neosalanx oligodontis, Embryonic development, Temperature, autumn continuous rain, basin area of Sichuan Province, agriculture, risk evaluation
