This study investigated the effects of seven microalgal diets, including single‐species diets of Rhodomonas salina (R), Tisochrysis lutea (T), and Pavlova lutheri (P), two‐species diets (R + T, T + P, and R + P), and a three‐species diet (R + T + P), on the cyclopoid copepod Paracyclopina nana growth, stage composition, and ovigerous female size and fecundity. Experiments were conducted in 10‐L beakers starting with nauplii from a 300‐L culture population. After 15 days of feeding, the R + T diet induced the greatest total population growth, particularly for copepodites and all female stages (preadult females, females, and ovigerous females). The R diet followed by R + T also generated the greatest individual size and clutch sizes in ovigerous females. Overall results show that the diets leading to the highest total population growth and clutch sizes in P. nana included R. salina. Conversely, P. lutheri was not a very effective microalga to enhance P. nana productivity in culture. Current results are the first to show that R. salina is a suitable microalga for production of P. nana for use as live food for marine fish larval aquaculture.

微藻饮食对Cyclopoid copepod Paracyclopina nana种群生长和繁殖力的影响

这项研究调查了7种微藻饮食的影响，包括单一物种饮食的红景天（Rhodomonas salina）（R），黄褐线虫（Tisochrysis lutea）（T）和帕夫洛娃（Pavlova lutheri）（P）两种饮食（R + T，T + P和R + P）和三种动物饮食（R + T + P），在摆线类co足类Paracyclopina nana上生长，分期组成以及雌雄同体的大小和生殖力。实验是从300升培养种群的无节幼体开始的10升烧杯中进行的。喂食15天后，R + T饮食诱导了最大的总种群增长，尤其是对于角足类和所有雌性阶段（雌性，雌性和有卵的雌性）而言。R饮食，然后是R + T，在有卵的雌性中也产生最大的个体大小和离体大小。总体结果表明，导致P. nana最高总人口增长和最大clutch食的饮食包括R. salina。相反，路德氏疟原虫不是增强纳氏疟原虫的非常有效的微藻。文化生产力。目前的结果是第一个表明R. salina是适合生产P. nana的微藻，用作海洋鱼类幼体水产养殖的活食。
