1.1 World Catch and Harvest Seafood has by far the greatest variety of all animal-based foods. Whereas the species consumed as warm-blooded mammals (beef, pork, lamb, goat, and donkey) or poultry (hen, turkey, geese, and duck) are represented by very few species, shes and other aquatic animals show an abundant
number of species and variability. e sh group alone is represented by 25,000-35,000 species. However, only a little proportion of this large number of about 5% is present in the world’s oceans in amounts huge enough to allow an economical use (catch and following processing). Further, only some of these 5% have the desired sensory properties and give a good or satisfying llet yield that catching and processing them can be justi ed.
