长吻(鱼危)是我国名贵经济鱼类之一。本文初步报道了1985—1987年进行长吻(鱼危)人工繁殖试验时,不同温度与鱼卵孵化的相互关系。在平均水温19.5—23.7℃时,数理统计分析结果如下:孵 化水温(t)与孵化时间(H)为负相关;孵化水温与积温(Y)之间为明显的负相关;孵化时间与积温正相关。
Long kiss (fish danger) is one of China’s economically valuable fish. This paper initially reported the relationship between different temperatures and hatching of fish eggs during the 1985-1987 artificial reproduction experiment. When the average water temperature was 19.5-23.7 ℃, the results of mathematical statistics analysis were as follows: the incubation water temperature (t) was negatively correlated with the incubation time (H); the incubation water temperature was negatively correlated with the accumulated temperature (Y); the incubation time was positively correlated with the accumulated temperature Related.
