Sport Diving and It's Economic Value: Are Artificial Reefs Different?

Green Bay, WI: University of Wisconsin, Public and Environmental Affairs Dept. and College Station, TX: Texas A & M University, Dept. of Wildlife and fisheries Sciencesport diving/coral reefs/economic use value/consumer's surplus/gross value/expenditures

The paper addresses two issues: 1) the economic value of sport diving to participants and 2) whether this economic value is different among users of artifical and natural reefs. The artificial reefs were oil and gas platforms, bottom reefs made of man-made materials, and wrecks. The natural reefs were the coral reefs of the Flower Garden Banks National Marine Sanctuary. Customer names were solicited from charter boat operators known to take divers to the Flower Gardens National Marine Sanctuary as well as other offshore areas in the Gulf of Mexico. A mail survey was sent to 1,059 divers with a response rate of 56.2% (528 respondents). Of this number, 461 had taken one or more sport diving trips into the Gulf of Mexico within the past 12 months. Of this group, 41.2% made trips only to the Flower Gardens National Marine Sanctuary. The remainder visited a combination of artificial reefs and the Flower Gardens National Marine Sanctuary (33.1%) or soley artificial reefs (25.7%). The total economic value of sport diving, a "use value" consists of both direct expenditures for participation and any residual value (consumer's surplus) not captured in the marketplace. Divers using the Flower Gardens spent $287.53 in the coastal area from which they departed on their dive charter and an additional $114.71 in other areas. Their total expenditure was $402.25 per sport diving trip. Estimated consumer's surplus was $141.62 per trip, making their total economic value $543.86 per trip. Sport divers using artificial reefs were found to have comparable expenditures of $402.90, but consumer's surplus attributable to their diving experience was only $109.19 per trip or $32.43 less than that for those who dove on the Flower Gardens. The net economic value of sport diving on the coral reefs of the Flower Gardens National Marine Sanctuary was 30% higher than that for sport diving on artificial reefs.

Economic value of sport diving from charter boats on the coral reefs of the Flower Gardens National Marine Sanctuary versus artificial reefs in the Gulf of Mexiico. Expenditures and consumer's surpluses compared between those using the Flower Gardens versus those that dove on artificial reefs.
