Composition, distribution and abundance of zooplankton and ichthyoplankton along the Senegal-Guinea maritime zone (West Africa)
A study of zooplankton and ichthyoplankton was carried out from samples collected along the Senegal-Guinea maritime area on board the Norwegian research vessel 'Dr Fridtjof Nansen' in November 2011. Nineteen groups of zooplankton were identified with a dominance of copepods representing 68...
