FISHERY PRODUCTS IN EVERYDAY LIFE 43 



Only the Mediterranean, North Atlantic, North Sea, 

 and North Pacific Oceans have been extensively 

 fished. Further, thousands of species of fish and 

 shell-fish occur in large quantities which are scarcely 

 utilized at all. Among fishes the outstanding example 

 of one that is caught in large numbers, yet is seldom 

 utilized, is the dogfish. It is very voracious and 

 destroys large numbers of young food fish. Sea 

 mussels are very plentiful along the coast of the 

 United States and are very good to eat, yet most of 

 those that are taken are used as bait.
