Abstract

The duration of development, survival rate, and reproductive characteristics of Calanipeda aquaedulcis (Krichagin, 1873) and Arctodiaptomus salinus (Daday, 1885) depending on a diet consisting of monospecific cultures of microalgae from three different taxonomic groups were studied in experimental conditions. The highest survival rates were recorded for the copepod C. aquaedulcis that was fed the microalga Prorocentrum cordatum (Ostenfeld) J.D. Dodge, 1975. A. salinus showed the maximum survival rate when it was fed the microalga Isochrysis galbana Parke, 1949. The duration of ontogeny in C. aquaedulcis was 14 days with each of the three diets. The shortest duration of development in A. salinus (18 days) was recorded when it fed on Rhodomonas salina (Wislouch) Hill and Wetherbee, 1989. The percentage of hatching nauplii in female C. aquaedulcis that were fed P. cordatum and I. galbana was 100%; however, when females were fed Rh. salina, it decreased to 86%. The average daily fecundity per life cycle in female C. aquaedulcis was found to be two times higher than that in A. salinus. The female A. salinus that received different diets showed significant differences in the average prosoma length and the diameter of spawned eggs; in C. aquaedulcis, these parameters did not depend on the species of food.

饲喂不同种类微藻的微咸水Co足类动物的繁殖和发育

摘要

在实验条件下，研究了Calanipeda aquaedulcis（Krichagin，1873）和Arctodiaptomus salinus（Daday，1885）的发育持续时间，存活率和生殖特征，具体取决于饮食，该饮食由来自三个不同分类组的微藻的单特异性培养物组成。最高的存活率都对桡足类C. aquaedulcis这是喂微藻原甲藻 cordatum（Ostenfeld）JD道奇，1975年。饲喂微藻等鞭金藻帕克（Esochrysis galbana Parke）时，盐沼曲霉（A. salinus）表现出最大的成活率，1949年。水产假单胞菌的个体发育持续时间三种饮食中的每种饮食都持续14天。在发展的时间最短A. salinus（18天）记录，当它取食Rhodomonas藻（Wislouch）山和韦瑟比，1989年女性孵化幼体的比例C. aquaedulcis是饲喂P. cordatum和一鞭金藻是100％；但是，当雌性喂食Rh。盐沼，下降到86％。发现雌性C. aquaedulcis每个生命周期的平均每日繁殖力比A. salinus高2倍。雌性A. salinus接受不同饮食的人的平均prosoma长度和产卵直径存在显着差异；在C. aquaedulcis中，这些参数不取决于食物的种类。
