Assessing the impact of removing reserve status on the Abore Reef fish assemblage in New Caledonia ArchiMer

Fish counts and habitat-related information were collected before and after the removal of reserve status, both inside and outside the reserve. Species groups were constructed on the basis of additional information on behavioural characteristics and taxonomy. The impact of the removal of reserve status was assessed by using 2 habitat proxies corresponding to 2 spatial scales and by considering several criteria for grouping species. Habitat...

Cela a non seulement entrai-né un accroissement considérable de l'effort de pêche et une certaine surexploitation des stocks, mais est aussi devenue une source nouvelle de conflits entre les pêcheurs continuant à employer les engins traditionnels et ceux utilisant les nouveaux engins. A la demande du Gouvernement, une mission FAO s'est rendue en Côte-d'Ivoire en mars-avril 1985 afin de préparer un plan d'aménagement des pêcheries lagunaires.
