Contributions of economics to the management of invasive species: the case of the common slipper-limpet in the bay of St-Brieuc

Abstract

This paper examines the contributions of economic science to the management of invasive introduced species as decision support. Starting from the case study of the invasion of the scallop fishery in the Bay of Saint-Brieuc by the common slipper limpet (Crepidula fornicata), an invasive species present in the Bay of Saint-Brieuc, we will illustrate the three areas of intervention in which economic science can shed light on the decision-making process for the management of invasive species: assessment of the costs of damage, identification of a so-called optimal management policy and incentive measures to correct the risk factors for the proliferation or introduction of invasive species. The more general contributions of economics are then discussed.
