Mike,
That is a Mako. We do a lot of shark fishing and usually tag around 70 sharks a season. We enjoy shark fishing. If we catch a Mako, he's dinner the rest usually get tagged and released.
Your trip to Belize sounds fantastic. In todays ecconomy it cost me more than $300.00 to go fishing for the day and I already own the boat. On a typical Tuna trip we usually burn around 250 gallons, @ $3.50 a gallon for Diesel fuel the trip costs $875.00 in fuel alone.
