Size at maturity of the Pacific bearded brotula (Ophidiidae: Brotula clarkae): a commercially exploited species in the Pacific of Costa Rica

The deep-water shrimp fishery is of great commercial importance along the Pacific coast of Latin America. In Costa Rica, shrimp resources have declined considerably over the last decade. Therefore, fisheries have shifted towards teleost species such as the Pacific bearded brotula Brotula clarkae. Li...
