The species that fishers target, the levelof exploitation, and the gear that they use are all influencedby the benefits they receive (i.e. the revenue) and the coststhey incur. Fisheries management changes the set of incentives facing fishers,and in doing so changes their behaviour. In some cases, managementimposes additional costs on their operation directly (e.g. limitingoutput, or inefficient technology mixes arising from input controls),while in other cases, costs are imposed indirectly through anew set of incentives created (e.g. displacement of fishersfrom one area has an impact on other fishers already operatingin the areas to which they move). Changes in fisher behaviournot only influence the costs to the industry,
