Economic and biological risk analysis of the Norwegian spring-spawning herring fishery
Résumé
The purpose of this paper is to study the biological and economic risks involved in the management of the
Norwegian spring-spawning herring fishery. We use a
discrete time and age-structured model based on
historical data. The current paper investigates, under
different levels of fishing mortalities, the risk
probabilities related to the time behaviour of the
spawning stock and profit. We show that the
exploitation of the herring stock is vulnerable to
small changes in harvesting and price level.
