The abundant calanoid copepod, Nannocalanus minor, is widespread from the Florida Straits (FS), throughout the Gulf Stream and the Sargasso Sea, to the eastern North Atlantic Ocean. Does the species represent a single, randomly-mating population across

Nannocalanus minor f. minor and Nannocalanus minor f. major (Sewell, 1929) from the northern Indian Ocean were reinvestigated. Differences in the structure of their genital segment and mouthparts between N. minor f. minor, N.m.f. major and N. minor (Claus,

By studying the biology of copepods, including their growth, survival and reproductive behaviour, we can obtain baseline information on the culture of particular species at the laboratory- and pilot-scale levels. This information can be used in the development
