The relative weight of traditions, economics and catch portfolios in New Zealand fleets dynamics

We investigate the relative weights of catch portfolios, expected profit and traditions in fishers’ decision-making for six contrasted New Zealand fleets regulated by Individual Transferable Quotas. Several métiers were defined for these fleets, using two different typologies. A nested logit RUM (Random Utility Models) was used to model the métier allocation of fishing effort in relation to catch plans, expected profit and past fishing allocations. This study showed that traditions and catch plans, which appeared to be determined to a large extent by an annual strategy, were the most important determinants of fishers’ behavior in the case of the New Zealand fleets being investigated. The model developed in this study fitted the data generally well, and was also able to predict in most cases future effort allocation both one month and one year ahead.
