jbrockey,
The company I work for does do some electro shocking and we charge in the range of 2000-2500 dollars. We have to pay alot of money for the insurance and equipment at a cost of about $1000 everytime the boat is dropped in the water. BUT with that we do more than just a fish survey. Once we have done the shocking we can better help the customer determine what he/she needs to do to create a better enviroment for their fish. We can determine if there is a good mix of fish in their waters or if we need to remove a species. We do have a crew of 3 or 4 biologists with fisheries background that help in these shockings so they really have a good understanding on the nature of the fish and their needed habitat. I guess I do not really feel that this is over priced when you look at the service that is provided and you can see what the cost is for the equipment (as well as the liability). Hope that this helps you in your decision.

Jerry
