The report presents the results of studies undertaken to develop a method of maintaining health, self-propagating, laboratory cultures of the freshwater calanoid copepod, Diaptomus clavipes. Recommendations are given as to the conditions of container size, type of culture medium, light conditions, temperature conditions, food type and quantity, frequency of replacement medium, and amount of disturbance suggested for culturing. The results of a study dealing with effects of temperature on certain reproductive attributes of this species are presented. The report includes the results from a study on the dynamics of a field population of D. clavipes. The durations of the various life history stages were estimated both from laboratory and field data. Life tables were constructed for the spring generation of this population as well as all generations in a reproductive year combined. The stages of greatest relative mortality were identified. The report also presents recommendations for culturing the cyclopoid copepod, Cyclops vernalis, and the results of studies concerning effects of temperature on certain reproductive attributes of this species.
