Both tourism and commercial fishing are prime potential sources of 

 income to any estuarine system. In the case of Apalachicola Bay, 

 these happen to be the major sources of income because of the nature

 commercial shipping facility. 



The San Diego economy, although heavily dependent upon the military 

 and shipping activities in the Bay, has diversified to the exte 

 that it is no longer completely dependent upon such uses of the Bay. 

 At the same time there has been a growinn demand for recreational 

 uses of the Bay. Evidence of the local resident's interest in the 

 Bay for recreation, tourism, and commercial uses can be found in 

 their willingness to invest substantial sums of money in facilities 

 to prevent pollution of the Bay by municipal wastes. 



Mission Bay, a separate estuary in the San Diego area, is an example 

 of the recreational potential to be found in an estuarine system. How-

 estuary may not come about naturally. Rather, it shows that a planned
