Standardization of the catch per swept area (CPUA) for direct stock assessment cruises of nylon shrimp (Heterocarpus reedi) (1998-2006)

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 ...

Using a length-based stock assessment model to evaluate population structure hypotheses of nylon shrimp Heterocarpus reedi (Decapoda, Caridea) exploited off central Chile

Fisheries Research, 2016
11 pages, 3 figures, 6 tables, 3 appendices Spatial processes are rarely considered explicitly in the evaluation and management of marine invertebrate populations. This is particularly true when larval drift acts as one of the main mechanisms of population expansion.

Distribución y abundancia de larvas de Heterocarpus reedi Bahamonde, 1955, Cervimunida johni Porter, 1903 y Pleuroncodes monodon (H. Milne Edwards, 1837), frente a Coquimbo y Caldera, Chile Distribution and abundance of Heterocarpus reedi Bahamonde, 1955, Cervimunida johni Porter, 1903, and Pleuroncodes monodon (H. Milne Edwards, 1837), larvae off Coquimbo and Caldera, Chile

Latin American Journal of Aquatic Research, 2011
Como aporte a la dinámica poblacional de especies que constituyen recursos pesqueros, se analizaron 160 muestras de zooplancton obtenidas con redes Bongo en 40 estaciones oceanógraficas entre Caldera y Coquimbo, en octubre y diciembre de 2005.

Distribution and abundance of Heterocarpus reedi Bahamonde, 1955, Cervimunida johni Porter, 1903, and Pleuroncodes monodon (H. Milne Edwards, 1837), larvae off Coquimbo and Caldera, Chile

Latin American Journal of Aquatic Research, 2011
To better understand the population dynamics of fishery resource species, 160 zooplankton samples were obtained with a Bongo net at 40 oceanographic stations around Caldera and Coquimbo in October and December, 2005, and analyzed. All crustacean decapod larvae were sorted, and Heterocarpus reedi, Cervimunida johni, and Pleuroncodes monodon larvae were ...

Remoción del potencial reproductivo por efecto de la pesca: el caso del camarón nailon (Heterocarpus reedi Bahamonde, 1955)

, 1997
Se propone un procedimiento numérico para calcular la remoción relativa del potencial reproductivo, por efecto de la pesca, y la desviación estándar asociada. La metodología de cálculo del estadístico de dispersión, sugerida aquí, es una forma paramétrica del método de remuestreo bootstrap.
