 and maintenance costs of $7 million per year."*' 



Several of the major success stories in meeting 

 recreational demands for fishing are due to the ability 

 of some anadromous species to prosper when re- 

 stricted to freshwater. Initially, striped bass were res- 

 tricted to Atlantic and Gulf coastal waters. In the late 

 1800's, they were introduced to the West Coast and 

 subsequently to inland areas. They are now found in 

 38 States.5o 



To balance such spectacular success stories, there 

 have been many more attempts that have failed. 

 Transplanting living organisms is always a gamble, as 

 it the artificial propagation of fish. Hatchery pro- 

 duction is generally most valuable when used to sup- 

 plement wild populations for relatively brief periods.
