Food and drink biodiversity:

Seafood

Whereas we derive most of our land-based food from domesticated animals and plants, most of the food we eat from the sea is derived from entirely wild species. With well over 30 fish species that are eaten regularly, at least five species of crustacean, at least 12 species of mollusc and at least two species of seaweed, we really do draw on an amazing diversity of wild life in the sea. 

Fish

Some of the more important marine fish eaten by people in southern Africa are listed below. 

Sardinops sagax (Pilchard or Sardine)
