North Atlantic fish stock recruitment, spawning stock biomass, weight at age and numbers at age

The correct prediction of the shape and strength of density-dependence in productivity is key to predicting future stock development and providing the best possible long-term fisheries management advice. We identify unbiased estimators of the relationship between somatic growth, recruitment and density, and applied these to 80 stocks in the Northeast Atlantic. The data used for the analysis is published here.

The data here have been used in an analysis of density dependent growth and recruitment currently submitted to Fish and Fisheries. The data set includes data on 25 species divided into 80 stocks.

N1= number at age 1 and so forth, W1= weight at age 1 and so forth. -1 denotes missing value.
