Wind Speed and Mortality Rate of a Marine Fish, the Northern Anchovy ( Engraulis mordax )
Abstract
Large variability in recruitment of marine fishes creates challenging management problems. In northern anchovy (Engraulis mordax), there is a significant linear relation between larval mortality rate and the frequency of calm, low wind speed periods during the spawning season, possibly because calm winds permit maintenance of concentrated patches of larval food. Neither cannibalism on larvae nor offshore transport contributed significantly to interannual variation in early larval mortality. These results are consistent with the hypothesis that wind-driven turbulent mixing affects variability in survival of young fish larvae. However, abundance of recruits does not necessarily reflect abundance of larvae surviving through this early stage.

When upwelling is too strong, turbulence and offshore advection could decrease fish production due to disruption of feeding strata and/or excessive offshore transport of planktonic larvae and prey away from favorable coastal habitats.
“Yet when upwelling is too strong, turbulence and offshore advection could decrease fish production due to disruption of feeding strata [87,88] and/or excessive offshore transport of planktonic larvae and prey away from favorable coastal habitats [86,89].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
