旧金山湾卤虫在同安盐田实验池中种群动态的初步分析

Preliminary study on population of Artermia franciscana in experimental pond of Tong'an saltfarm during autumn and winter

美国旧金山湾卤虫于1989年引入同安盐田实验池养殖,1989年10月至1990年3月池内人工养殖卤虫的结果表明,秋、冬两季实验池的水温变化不是影响卤虫种群数量变动的主要原因,卤水盐度的变化对卤虫幼体群体数量有较大的影响,饵料是影响卤虫种群变动的主要因子,使用花生渣饼磨浆后投喂卤虫比使用干鸡粪更有利于卤虫种群的增长。实验证实旧金山湾卤虫能在同安盐田安全越冬.

Brine Shrimp of Artermia franciscana was introduced and cultured in the experimental pond ofTong'an saltfarm in Fujian,China,in 1989～1990.The dynamics of population under the effectingfactors of termperature,salinity and food during the period of October 1989 to March 1990 was anal-ysed.The results showed that the temperature was not so important to the change of population size asto that of salinity which increased the numbers of nauplii resulted from higher hatching rate due to lowsalinity at the water surface.The food used was the most important factor affecting the growth ofbrine shrimp population.Compared to chicken dung,the grounded peanut residue,by-products ofpeanut oil,as food showed a better result for the growth of Artemia population.
