^ EGG COLLECTIONS 



The degree of success attained in the collection of fish eggs depends 

 largely upon the local conditions prevailing when the fish are spawn- 

 ing. If they are such that it is impossible for the commercial fisher- 

 men to set their nets or lift them at proper intervals, large numbers 

 of eggs invariably are lost. Especially is this true with regard to 

 operations with the commercial fishes of the Great Lakes. The 

 various hatcheries on the Atlantic coast likewise are dependent upon 

 the success of the commercial fishermen, though the catch is not 

 influenced to a great extent by weather conditions. The market price 

 of fish is a factor of considerable importance in the work of collecting 

 eggs in this region. In the upper Mississippi Valley buffalo-fish eggs 

 were collected from fish caught in the nets of commercial fishermen, 

 and after being fertilized they were planted in suitable waters to be 

 incubated under natural conditions.
