By-catch associated with fisheries of Heterocarpus vicarius (Costa Rica) and Heterocarpus reedi (Chile) (Decapoda: Pandalidae): a six-year study (2004-2009) [PDF]
Journal of Crustacean Biology, 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 shrimp fisheries by year, latitude, and bathymetry.

Journal of Applied Ichthyology, 2012 The size selectivity of alternative codends for nylon shrimp and yellow squat lobster was studied off the Chilean coast using the covered codend technique. Various mesh sizes (47 and 63 mm mesh opening) and shapes (diamond and square) in the codends were used.

Improved interspecific selectivity of nylon shrimp (Heterocarpus reedi) trawling in Chile
Latin American Journal of Aquatic Research, 2009 In order to improve the inter-specific selectivity of a new bottom trawl design for demersal crustaceans, an experimental attempt was carried out to compare the shrinkage effect in length of net structure accessories, particularly shorter bridles and sweeps, based on previous studies on escape behavior of gadiform fishes.

An economic analysis of the Heterocarpus reedi and Cervimunida johni fisheries off northern-central Chile, from 1997 to 2000 [PDF]
Investigaciones Marinas, 2007 Se analizo el efecto economico debido a la disminucion de la captura por unidad de esfuerzo (CPUE) en la pesqueria de camaron nailon y langostino amarillo en la zona norte y central de Chile durante el periodo 1997-2000. Se utilizo un modelo de simulacion biologico-tecnologico que da cuenta de variables de desempeno fisicas y biologicas.

Latin American Journal of Aquatic Research, 2011 This work analyzes the operational data of direct stock assessment cruises carried out on nylon shrimp (Heterocarpus reedi) off the central coast of Chile between 1998 and 2006. These data were modeled using the product of the expected CPUA (catch per unit area) for hauls with catch and the probability of catch (that is, catch greater than zero) to ...

Un modelo simple para describir la dinámica de la biomasa del camarón nailon Heterocarpus reedi en Coquimbo, Chile [PDF]
Investigaciones Marinas, 2005 A daily record of space/time dynamics was carried out on CPUE (ton·trawl -1 ) for the nylon shrimp trawl fishery based at Coquimbo, Chile, between September 1997 and August 2000. A modified biomass depletion model was constructed to analyze the temporal variations in CPUE based on the concepts of abundance (total population biomass) and availability ...
