Estimación de la talla media de madurez sexual en Trachurus murphyi mediante parámetros del consumo relativo de oxígeno Estimation of size at first maturity for Trachurus murphyi using relative oxygen consumption

Latin American Journal of Aquatic Research, 2010
Se usa un método alternativo para estimar la talla de madurez del jurel, que considera el consumo relativo de oxígeno en función del peso corporal y la constancia que ocurre en peces teleósteos entre el consumo relativo de oxígeno en la madurez y el ...

Re-evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 2. [PDF]

EFSA J
Abstract The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free of zoonotic parasites. In this Opinion the term ‘fishery products’ only refers to fresh finfish.

Genetic analysis provides insights into species distribution and population structure in East Atlantic horse mackerel (Trachurus trachurus and T. capensis). [PDF]

J Fish Biol, 2020
Abstract Two sister species of horse mackerel (Trachurus trachurus and T. capensis) are described that are intensively harvested in East Atlantic waters. To address long‐standing uncertainties as to their respective geographical ranges, overlap and intraspecific population structure this study combined genetic (mitochondrial DNA and microsatellite ...

Habitat Variations of Two Commercially Valuable Species Along the Chilean Waters Under Different-Intensity El Niño Events

Frontiers in Marine Science, 2022
The synchronous response of the spatial distribution pattern of Dosidicus gigas and Trachurus murphyi habitat along the Chilean waters to different-intensity El Niño events was examined based on the habitat suitability index (HSI) models inclusive with ...

Combining potential and realized distribution modeling of telemetry data for a bycatch risk assessment. [PDF]

Ecol Evol
We applied telemetry data of a mobile and widespread species in a combined distribution modeling framework (distribution was modeled at the population‐level and individual‐level). In our northern Chile study system, the combined predictions of South American sea lions revealed unique patterns of habitat use across scales.

Effect of slaughter methods on the quality of Chilean jack mackerel (Trachurus murphyi) during refrigerated storage. [PDF]

J Food Sci Technol, 2015
The main objective of this study was to assess the influence of slaughter methods on the quality of Chilean jack mackerel (Trachurus murphyi) during refrigerated storage on board. Fishes were slaughtered by asphyxia in air (AA), asphyxia in ice water (AI) or stunning fish heads (SH), and the rigor mortis, pH, total volatile basic nitrogen (TVB-N ...

Biocultural Calendars Across Four Ethnolinguistic Communities in Southwestern South America

GeoHealth, Volume 7, Issue 4, April 2023., 2023
Abstract Since the mid‐20th century, the so‐called Great Acceleration (sensu Steffen et al., 2007, https://doi.org/10.1579/0044-7447(2007)36[614:TAAHNO]2.0.CO;2) has amplified processes of ecosystem degradation, extinction of biological species, displacement of local peoples, losses of languages, and cultural diversity.

Accuracy of the Kirchhoff-approximation and Kirchhoff-ray-mode fish swimbladder acoustic scattering models. [PDF]

PLoS ONE, 2013
The acoustic backscatter from pressure release prolate spheroids and a three-dimensional representation of a fish swimbladder (Chilean jack mackerel, Trachurus symmetricus murphyi) was calculated using four target strength models (Kirchhoff-approximation,
