,Influence of experimental conditions on nitrogenous excretion by Lake Michigan , (Lovén): laboratoren 4 and 8 h of incubation were significantly higher than those between 1–3 h and 8–15 h, for mysids held both in filtered water and in . cultures. The results are compared to those from shipboard incubations in a previous study and are discussed with respect to physiological regulation of nitrogenous waste production.

Mysids in toxicity testing - a review,sms desirable for research purposes. Continued research using mysid species will probably demonstrate even greater usefulness of these organisms in assessment of pollutant impacts on estuarine or marine communities.

An Example of Non-Gaussian Density Process, field observations and a relationship between the salinity and temperature of seawater and abundance of juveniles in May to June, and November to January in Bombay coastal waters (west coast of India) was established. Seawater of reduced salinity was found to be a major factor for occurrence of juvenile .in abundance.
