Despite a ban on fishing in the Gulf of Nicoya for environmental reasons, some 60 fishermen in 32 small boats were spotted doing just that.
The Servicio Nacional de Guardacostas and workers from the Instituto Costarricense de Pesca y Acuicultura were surrounded by the boats and the occupants wearing ski mashes, they reported. They called the action intimidation.
The confrontation took place last week near the Isla Chira in the gulf.
The coast guard officers managed to confiscate some 2,000 meters of nets that had openings smaller than those specified by law.
The unidentified fishermen attempted to impede the confiscation of the nets, said the coast guard.
The case has been referred to prosecutors in Puntarenas.
While the seasonal ban is imposed in the gulf, the fishermen and their families receive subsidies from the Instituto Mixto de Ayuda Social, the coast guard noted.
