foundation. So it is with the pilchard fishery of Cahfornia, the oyster 

 fishery, and the crab fishery. Headway is also being made for 

 conservation of other fisheries. 



Among the species of moderate commercial importance are 24 

 products whose yield makes up 15 per cent of the average annual catch. 

 Included with this group are many whose catch in the past greatly 

 exceeded the present yield — shad, lobster, and sturgeon being con- 

 spicuous examples. Many of the species of this group are showing 

 increased yield as time goes on, and possibly greater numbers of 

 these will be taken in the future. 



Among the species of least importance are 108 products whose 

 annual catch accounts for only 5 per cent of the total annual yield. 

 In former years some species of this group would have ranked with 

 the first group of products, especially ciscoe taken on Lake Erie. 

 Others in this group are considered of little commercial importance, 

 due either to their very limited supply, or to the inferior quality of the 

 fish.

YIELD OF FOOD FISHERY PRODUCTS, BY VALUE 



When considered from a monetary standpoint, 18 products account 

 for 80 per cent of the value of the entire catch. Listed in order of 

 importance they are — salmon, oysters, haddock, halibut, shrimp, 

 lobsters, flounders, cod, tuna and tunalike fishes, mackerel, clams, 

 shad, pilchard, squeteagues, crabs, sea herring, lake trout, and mullet. 

 In this line-up some of those species leading in volume trail behind 

 in value, and with others the case is vice versa. This is noted with
