By attributing an economic value to these commercial, non-quantifiable 

 activities (see app. C), it was possible to estimate the value of these 

 private non-commercial activities at Looe Key. Using the combined commercial 

 costs of snorkeling, and SCUBA diving, the economic value of the 9,694 to 

 19,061 private divers in Boundary Option No. 2 was estimated to be between 

 $137,364 and $240,094 in 1978. Using the appropriate regional multiplier, 

 the value of private recreational diving activity to the region was set 

 between $439,976 and $769,021 for the region. 



Recreational fishing and sightseeing was valued to be between $27,520 

 and $93,440. The multiplier effect of this activity would raise the total 

 value of this activity to the region to between $152,200 and $299,288. 



5. Summary 



The income from commercial and recreational activities is approximately 

 $1,300,000 per year, which, in turn provides about $3,154,000 in business 

 for the area economy. 



The economic impacts of human activity in the Looe Key area were consid- 

 ered in the drafting of regulatory alternatives. The approximate income and 

 business volume in dollars is summarized in the following table:
