Recommend you E-mail Severo Guerrero, E-mail: [email protected]
He is a excellent fishing guide and may be able to answer your question or refer you to someone who will. Recommend you distinguish to him if you are interested in the income of fishing guides or commercial fishermen; the former take out tourists to catch fish and the latter fish by a variety of methods to catch and sell fish & lobsters. Severo is a very nice man and is also San Pedro's deputy mayor. Good luck with the project!
