The breeding biology of Euchaeta norvegicn (Boeck) has been studied in Loch Etive, Scotland, between 27 September 1971 and 24 August 1972. Information is presented on seasonal variations in the sex ratio of adults (stage VI), as well as stage IV and stage V copepodites, and examines the proportion of males present in the adult population as a factor determining the numbers of spermatophores attached to adult females and the quantity of egg sacs produced. These parameters are used to provide a measure of the intensity of mating, fertilization and breeding.
