The influence of the well-known 1976–1977 regime shift on the Northern anchovy (Engraulis mordax) and the Pacific sardine (Sardinops caeruleus) populations in the California Current System (CCS) is investigated using a climate-to-fishery model.

The status of the Pacific sardine resource and its management [PDF]
The Pacific sardine fishery has declined from a catch ofalmost 8 hundred-thousand tons in the nineteen thirties torelative insignificance at present. This decline was primarilydue to the decline of the northern subpopulation.Scientists feel that the only

Oxygen: a fundamental property regulating pelagic ecosystem structure in the coastal southeastern tropical Pacific. [PDF]
BACKGROUND: In the southeastern tropical Pacific anchovy (Engraulis ringens) and sardine (Sardinops sagax) abundance have recently fluctuated on multidecadal scales and food and temperature have been proposed as the key parameters explaining these ...

Temporal and spatial variability in 'Tetracotyle' type and metacercariae infection in the South African sardine, Sardinops sagax [PDF]
Spatial and temporal variation of "tetracotyle" type metacercariae infection in the eyes of the South African sardine, Sardinops sagax, was examined to elucidate the potential use of this parasite as a biological tag, and to test the hypothesis that the ...
