Comparison of predictive models for explaining the number of eggs per fish for wild Atlantic salmon collected around Ireland. GLM (generalized linear models) with a negative binomial distribution and a log link were used. Akaiki’s information criterion (AIC) is given to indicate goodness of fit. The predictive power of the model is indicated by the explained deviance. Insignificant variables which can be dropped without losing explanatory power are indicated in the “Drop1” row (Venables and Ripley, 2002).
