摘要
本文报道了１９９５年６－９月间对海水施肥鱼虾混养受控围隔生态系中浮游纤毛虫的种群增长和生产量估测结果。纤毛虫的种群增长率和世代时间是通过原位试验所得。养殖期间（温度为２２．６－２９．７℃）优势种具沟急游虫（Ｓｔｒｏｍｂｉｄｉｕｍｓｕｌｃａｔｕｍ）世代时间为６．５４－１９．８０ｈ其种群增长率为０．０３５－０．１０６ｈ－１；其种群增长受温度和食物量的影响。该围隔浮游纤毛虫累计日均产量为１００６．３４ｍｇ·ｍ－３ｄ－１。按月计算的日Ｐ／Ｂ为０．５４－２．４８。
This paper is reported the results of population growth and production estimation of planktonic ciliates in a controlled enclosure ecosystem rearing tilapia and shrimp with fertilizer from June to September 1995. Population growth rate and generation time was obtained through in situ experiment. During the culture season (temperature 22.6-29.7℃), the generation time of the dominant species Strombidium sulcatum was 6.54-19.80h, population growth rate 0.035-0.106h -1 . The population growth of S. sulcatum was affacted by temperature and amount of food. Average daily production of total planktonic ciliates in the enclosure was 1 006.34mg.m -3 d -1 , the value of daily P/B calculated monthly 0.54-2.48.
