“…La especie fue identificada en forma reciente (Guerra et al, 2009). Su pesquería se desarrolla a nivel artesanal en Perú y norte de Chile durante prácticamente todo el año (Rocha & Vega, 2003). Si bien la historia de capturas a nivel interanual refleja el incremento en la demanda del recurso (Defeo & Castilla 1998;Cardoso et al, 2004), aumentos marcados en las capturas totales de Perú se asocian a los eventos de El Niño (Cardoso et al 2004), al igual que la expansión hacia el sur de las zonas donde se registran desembarques en Chile.…”

“…D. gigas's population structure is not well defined, but based on individual mantle lengths it may include three stocks: large, medium and small sizes (Argüelles et al 2001). Small-scale fisheries, particularly off Peru, Chile and Mexico, traditionally exploited these stocks (Nevárez-Martínez et al 2000, Rocha andVega 2003). However, since the early 1990s there has been an increase in industrial vessels, largely from East Asia (Japan, Korea and China), fishing off Peru and Central America, with a resulting increase in squid catches from the eastern Pacific Ocean (Ichii et al 2002).…”

Environmental influences on commercial oceanic ommastrephid squids: a stock assessment perspective

et al. 2017

Summary:Ommastrephid squids are short-lived ecological opportunists and their recruitment is largely driven by the surrounding environment. While recent studies suggest that recruitment variability in several squid species can be partially explained by environmental variability derived from synoptic oceanographic data, assessment of ommastrephid stocks using environmental variability is rare. In thisstudy, we modified asurplus production model to incorporate environmental variability into the assessment of threeommastrephid squids (Ommastrephes bartramii in the northwest Pacific, Illex argentinus in the southwest Atlantic and Dosidicus gigas in the southwest Pacific). We assumed that the key environmental variablessuitable sea surface temperature on spawning grounds during the spawning seasons and feeding grounds during the feeding seasons-have effects on the carrying capacity and the instantaneous population growth rate, respectively, in the surplus production model. For each squid stock, the assessment model with environmental variability had the highest fitting accuracy and the lowest mean squared error and coefficient of variation, and the management reference points based on the optimal model were more precautionary. This study advances our understanding of the interactions between the environment and ommastrephid squid population dynamics and can therefore improve the management of these commercially valuable stocks with a short life cycle.Keywords: Ommastrephid squids; Ommastrephes bartramii; Illex argentinus; Dosidicus gigas; stock assessment; environmental factors.Influencia de factores ambientales sobre potas oceánicas (Cephalopoda: Ommastrephidae) explotadas comercialmente: un enfoque para la gestión de stocks Resumen: Los miembros de la familia Ommastrephidae (potas) son cefalópodos de vida breve y oportunistas ecológicos, estando sus reclutamientos profundamente influidos por el ambiente circundante. Aunque algunos estudios recientes sugirieron que la variabilidad del reclutamiento en varias especies de esta familia podría explicarse parcialmente por la variabilidad ambiental derivada de datos oceanográficos sinópticos, la gestión de los stocks de omastréfidos empleando factores medioambientales es muy poco frecuente. En el presente trabajo, se ha modificado un modelo de producción generalizada incorporando en él factores ambientales con objeto de ofrecer una herramienta para la gestión y manejo de tres pesquerías: la de Ommastrephes bartramii en el Pacífico Noroeste, la Illex argentinus en el Atlántico sudoeste y la de Dosidicus gigas en el Pacífico sudoeste. Se asumió que los factores ambientales clave: una apropiada temperatura superficial en las áreas de puesta durante las épocas de freza y en las áreas de alimentación durante las estaciones de nutrición, tenían efectos sobre la capacidad de carga y el crecimiento instantáneo de la tasa de crecimiento de la población, respectivamente, en el modelo de producción generalizada. Para el stock de cada especie, el modelo de gestión con las variables a...

“…The family Loliginidae Lesueur, 1821 includes many species that are important in fisheries world-wide (Nesis 2003, Okutani 2005, Jereb et al 2010) and in the southeastern Pacific Ocean (Cardoso 1991, Rocha & Vega 2003. At present the phylogenetic taxonomy of the Loliginidae is very confusing, resulting in a number of taxonomic problems that need to be critically resolved.…”

In the present paper the species from the genus LolligunculaSteentrup, 1881 (Cephalopoda: Loliginidae) in Southeastern Pacific Ocean are reviewed. The presence of Lolliguncula (Lolliguncula) panamensisBerry, 1911, Lolliguncula (Loliolopsis) diomedeae Hoyle, 1911 and Lolliguncula (Lolliguncula) argusBrakoniecki and Roper, 1985 are confirmed from Mexican waters to Perú and the species Lolliguncula (Lolliguncula) arguscollected during a cruise of the R/V Anton Bruunfrom 1966 off the coast of South America is recorded for the first time in Peruvian waters. A key to identification of Pacific species is given. We report a diagnostic feature with taxonomic remarks of these species. Updated information on the distribution, biology, and fisheries of each species also is discussed.
