The conventional selectivity paradigm is briefly reviewed and its performance examined from an ecosystem perspective. It is stressed that the overall (cumulative) selectivity of the harvest process in an ecosystem is the result of nested selection by fishers and fisheries of: (i) habitats; (ii) species assemblages; (iii) populations and (iv) individuals. A range of ecosystem models predict a strong impact of concentrated fishing (selective fishing) on the ecosystem structure stability, resilience and productivity. There seem to be advantages (in both yield and maintenance of ecosystem structure and functioning) to distribute fishing pressure broadly across available species and ecosystem compartments. Balanced harvesting was therefore defined by the... |

Integrated Coastal Zone Management (ICZM) is a link between three main fields: environment, society and economics. All of them are under strong and contradictory pressures with numerous factors and limited up-to-date and consistent knowledge. Nevertheless, decision makers have to find methods and means to manage the sustainable development of the coastal area, a place where different and frequently conflicting uses are steadily increasing, notably along the Mediterranean coastline. Numerous guidelines are available but their usual and common sense recommendations are rarely applied. The actor-network theory (Callon & Latour) could be a useful tool to clarify and reduce chronic resource use conflicts in coastal areas. The usefulness and efficiency of... |
