Habitat selection by fish in an artificial reef in Ilha Grande Bay, Brazil

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 s...
