In Galapagos, the two main industries are tourism and fishing…and they do not always get along very well. Galapagos Fishermen resent any sort of catch limit, which biologists maintain are necessary to maintain the delicate ecosystems in the archipelago. Fishermen also like to catch certain species, such as sharks (the fins can be sold for a handsome profit) that Galapagos visitors want to see, bringing them into conflict with those in the tourism industry. In a famous incident in 2004, angry fishermen occupied park facilities and the Charles Darwin Research Station (basically holding Lonesome George hostage) in protest of fishing limits.
