The Brownstriped grunt, Anisotremus moricandi (Ranzani 1842) (Fig. A, adults and B, juvenile) belongs to the family Haemulidae, reachs about 18 cm and is distributed in the western Atlantic, from Panama to Espirito Santo, Brazil. It is considered a coastal solitary species with nocturnal activities living in rocky bottoms (Acero & Garzón 1982). From December 2004 to January 2007, three schools of A. moricandi (with 3, 5 and 8 fishes) were observed during six diurnal SCUBA dives in the Itacipanema reef (38º 57' 53” W - 16º 15' 46" S), South of Bahia and nine schools (with 3 - 11 fishes) during seventeen free diurnal dives in the Picãozinho reef (34º 48'45" W - 7º 06' 45" S), João Pessoa, Paraíba, both in NE Brazil. Although it is pointed in the Red List of Threatened Species - IUCN (Acero 1996) and also under high fishing pressure by Floeter et al. (2006), authors´ personal observations indicate that A. moricandi is not a main target, neither for commercial or artisanal fisheries in the states of Bahia and Paraíba. Underwater observations, however confirms that this species may present diurnal and gregarious habits, including mixing with other Haemulidae species, which indicates that strategies to conserve A. moricandi populations in NE Brazil should place strong emphasis on the conservation of their habitats, especially the biogenic coastal reefs, and no requiries on fishing pressure reduction.
