Effect of climate on recruitment success of Atlantic Iberian sardine Sardina pilchardus
Open accessAbstract
The aim of this study was to determine how climatic (North Atlantic Oscillation winter index, NAO, December through March), oceanographic (upwelling intensity, turbulence, water column stability and larval offshore transport) and biotic (adult abundance) factors affect recruitment success of Sardina pilchardus off the northwest coast of the Iberian peninsula. Annual sardine juvenile landings in the port of Vigo (Spain) from 1980 to 2000 were used as an indicator of sardine recruitment success. Ekman transport along the x-axis (Qx) in February (QxF), from March to April (QxMA), from May to August over the preceding year (QxMJJA), and NAO explained 86% of the variance observed in catches of sardine juveniles. Due to the north-south orientation of the west coast of the Iberian peninsula, upwelling intensity and larval drift offshore are higher the lower the Qx. Landings of sardine juveniles were higher in those years with moderate QxF, high QxMA, low QxMJJA and low NAO values. There was a dome-shaped relationship between sardine juvenile landings and QxF. Under both high and low Qx conditions, the upper layer is strongly mixed. Therefore, the reduced recruitment success observed at both high and low QxF values could be due to a stratified upper layer in February enhancing primary production during the spring bloom and, hence, larval food availability. As March and April are the main spawning periods for sardine in this area, the reduced sardine recruitment success observed as QxMA decreased was probably due to the transport offshore of eggs and larvae. In this area the main upwelling season is from May to August. Therefore, the positive relationship between upwelling intensity from May to August and nutrient concentration in surface layers could explain why landings of sardine were higher when QxMJJA over the preceding year was lower. Finally, in years with low NAO sardine recruitment success was higher. When NAO is lower than average, the winter/spring temperatures are warmer and transport offshore is lower.

The importance of food availability on recruitment is also found in other marine fishes, e.g., Pomacentrus amboinensis, Sardina pilchardus, and North Sea cod.

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.
