Aires marines protégées et récifs artificiels : méthodes d'évaluation, protocoles expérimentaux et indicateurs ArchiMer
Claudet, Joachim.
Marine Protected Areas' (MPAs) and Artificial Reef's (ARs) management requires complex assessment and monitoring programmes, dealing with different sources of variability. We studied and developed experimental designs and analysis methods suited for the establishment of a monitoring of MPAs and ARs. This methodology is developed from existing data sets in the Northwestern Mediterranean. We build multi-criteria indicators allowing a statistically testable diagnosis of the impact of MPAs and ARs on reef fish assemblages. Using ecological performance indicators permits to monitor and to give an image of the assessed system to managers. It was possible to show the global response of the fish assemblages to the protection by a MPA. This response was evidenced...

Habitat selection by fish in an artificial reef in Ilha Grande Bay, Brazil BABT
Brotto,Daniel Shimada; Araujo,Francisco Gerson.
The use of artificial structures as a shelter for fishes was evaluated aiming to assess increase in fish abundance in Ilha Grande Bay at Southeast Brazilian coast (Lat: 22°8'-23°5' S; Long. 44º05’-44º40’W). Five different types of structures, made of clay tiles, with an increase range on size and complexity were tested to assess their efficiency. Fish were counted in each type of structure from May-1996 to April-1997 by underwater observation made with snorkelling. According to the pattern of concentration in the structures, two groups of fishes were identified. One comprised by E. guaza, M. rubra, R. randalli, S. hispidus, Sphoeroides sp and Haemulun sp showed affinity for hard bottom, irregular profile and an increase in abundance on the more complex and...
