Abstract
The objectives of this study were to evaluate existing techniques for culturing three species of the genus Mysidopsis that are routinely used as toxicity test organisms. A comparison of the life history, ecology and distribution of M. bahia, M. bigelowi and M. almyra is presented. Culture systems are described, supplemental foods are suggested, and guidelines are given for salinity, temperature, dissolved oxygen and nitrogen levels that will maintain optimum laboratory culture conditions. Methods are outlined for harvesting juveniles and controlling contaminant organisms, and general feeding procedures are described. Culture management is stressed as the most significant factor in maintaining productive mysid cultures. Specific recommendations are made regarding culture density, harvesting frequency, sex ratio and introduction of feral animals.
