Vertical Distributions Of Calanus-Finmarchicus And Calanus-Helgolandicus (Crustacea Copepoda)
The vertical distributions of the spring populations of Calanus finmarchicus (Gunnerus) and C. helgolandicus Claus are described and compared. The differences we observed between the two species have probably confused the understanding of the vertical distribution and development of the populations...
