Relations between recruitment indices and occurence in cod stomachs of pre-recruits of cod and haddock in the Barents Sea

Abstract

The predation by North-East Arctic cod on pre-recruits of cod and haddock is reviewed based on data from the joint PINRO-IMR stomach content data base. It is investigated how the abundance indices from surveys of pre-recruits are correlated with the occurence in cod stomachs of pre-recruits of these species. Estimates of the consumption of cod and haddock by cod based on a new model for the stomach evacuation rate of cod are also given.
