| 摘 要： | 在实验室条件下观察研究培养液的浓度、盐度、ｐＨ值及环境温度对旋毛蟹栖拟阿脑虫在单因子和综合因子作用下生长繁殖的影响，结果证明：在单因子作用条件下，随着培养液浓度的增加，其虫体种群的内禀增长率（ｒｍ）随之增加，达一定浓度时则停止增加，盐度在８—５５ｇ·Ｌ－１时，虫体可繁殖生长，３５ｇ·Ｌ－１时，ｒｍ最大；温度在４—３２℃范围内可生长繁殖，２５℃时ｒｍ最大；ｐＨ为５—９时，虫体可生长繁殖，ｐＨ为７时，ｒｍ最大。综合因子作用分析表明：温度与盐度对ｒｍ的影响显著，ｐＨ值在实验范围（５—９）无显著影响。当ｐＨ＝５—９、温度２２．１℃、盐度２２．４ｇ·Ｌ－１时，旋毛蟹栖拟阿脑虫的ｒｍ最大，而盐度和温度间具明显的交互作用。

| Abstract: | The effects of food and environmental factors on the reproductive rate of Para nophrys carcini spiralis were studied in this paper. Shrimp gravy and peptone solution were used as culture medium for P. carcini spiralis. It was found that P. carcini spiralis multiplied in both media and grew well in peptone solution.Single factor experiments were used firstly to investigate the effects of temperature, salin ity, and pH value on the intrinsic rate of increase of P. carcini spiralis. It was found that P.carcini... |
