The incorporation of acoustic technology into the Canadian Pacific sardine (Sardinops sagax) survey

open access: yes, 2012
Hydroacoustics can provide cost-effective ways of improving the accuracy of non-acoustic surveys, such as Canada’s annual nighttime Pacific sardine (Sardinops sagax) surface trawl survey. Seasonal sardine abundance in Canada is currently estimated by extrapolating average catch densities from this survey to 30 m depth over a distributional area.

Diet of sardine Sardinops sagax in the southern Benguela upwelling ecosystem [PDF]

open access: yes, 2006
The diet of sardine Sardinops sagax in the southern Benguela was investigated by microscopic examination of stomach contents. The relative dietary importance of prey size and prey type was assessed by calculating the carbon content of prey items. Sardine

Coupling between the environment and the pelagic resources exploited off northern Chile: ecosystem indicators and a conceptual model Acoplamiento entre el ambiente y los recursos pelágicos explotados en el norte de Chile: un modelo conceptual

open access: yesLatin American Journal of Aquatic Research, 2008
The eastern boundary of the Chile-Peru Current System constitutes one of the most biologically productive ecosystems in the world, due largely to coastal upwelling and the horizontal advection of nutrients.
