Recruitment to the blue whiting stock may possibly be predicted

The very variable size of the blue whiting stock is determined both by fishing pressure and by the recruitment of young fish.

A new article, for the first time, provides an explanation of why recruitment changes so dramatically from one year to the next.

Shifting wind patterns west of Ireland control the marine environment at the spawning grounds of blue whiting, which in turn determines how many eggs and larvae survive. This knowledge may make it possible to predict recruitment to the stock up to a year in advance.

If this truly succeeds, it can support our management and utilization of this ecologically and economically important fish species.

The article is published in the journal ICES Journal of Marine Science and can be read here.
