By-catch associated with fisheries of Heterocarpus vicarius (Costa Rica) and Heterocarpus reedi (Chile) (Decapoda: Pandalidae): a six-year study (2004-2009)
(Journal of Crustacean Biology, 33(2), 198-209. 2013, 2013)
Growing concern about the quantity and diversity of by-catch species caught in the bottom trawling nets of crustacean fisheries led us to compare the quantity of by-catch recorded in Chilean and Costa Rican deep-water ...
Feeding habits of the Pacific bearded brotula Brotula clarkae Hubbs, 1944 (Ophidiidae) along the Pacific coast of Costa Rica, Central America
The present study analyzed the diet composition, ontogenetic shifts and dietary overlap of Brotula clarkae in relation to stage of maturity and sex. Samples were collected from the trawling fishery along the Pacific coast ...
Mercury levels in muscle tissue of four common elasmobranch species from the Pacific coast of Costa Rica, Central America
Mercury (Hg) is a non-essential and toxic element that is ubiquitous in the marine environment and biomagnifies through food webs. Given the high trophic position of many elasmobranch species, it is important to quantify ...
Elasmobranch bycatch associated with the shrimp trawl fishery off the Pacific coast of Costa Rica, Central America
Demersal sharks and rays are common yet vulnerable components of the bycatch in tropical bottom-trawl fisheries. Little is known about the elasmobranch assemblages associated with most of these fisheries, particularly ...
Differentiation in reproductive traits of geminatemangrove crabs of the genus Aratus (Decapoda: Brachyura)across the Central American Isthmus
The mangrove crab Aratus pisonii was considered to have an amphi-American distribution; however, a recent study revealed that the Eastern Tropical Pacific populations were genetically distinct, thus representing a new ...
The deepwater fishery along the Pacific coast of Costa Rica, Central America
(Lat. Am. J. Aquat. Res., 37(3): 543-554, 2009, 2009)
Global catches of marine fishery resources declined during the last decades; however, there has been a trend of increasing exploitation of deepwater resources that are especially vulnerable to depletion. Such a tendency ...
Size at maturity of the Pacific bearded brotula (Ophidiidae: Brotula clarkae): a commercially exploited species in the Pacific of Costa Rica
Talla de madurez sexual del congrio rosado (Ophidiidae: Brotula clarkae): una especie de importancia comercial en el Pacífico de 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 ...
