Assessment of the effectiveness of two marine reserves in the Canary Islands (eastern Atlantic)
We assessed the effectiveness of two marine reserves (MRs) in the Canary Islands (eastern Atlantic), called "Punta La Restinga-Mar de Las Calmas" (El Hierro Island) and "Isla La Graciosa e islotes del norte de Lanzarote" (Chinijo Archipelago). Specifically, we evaluated the varia...

We assessed the effectiveness of two marine reserves (MRs) in the Canary Islands (eastern Atlantic), called "Punta La Restinga-Mar de Las Calmas" (El Hierro Island) and "Isla La Graciosa e islotes del norte de Lanzarote" (Chinijo Archipelago). Specifically, we evaluated the variability in the abundances and biomasses of four commercially-targeted fish species: the parrotfish (Sparisoma cretense), the island grouper (Mycteroperca fusca), the white sea-bream (Diplodus sargus cadenati) and the zebra sea-bream Diplodus cervinus cervinus) Four fishing managemente categories were established within and around each MR: (1) a no-take or integral area (collection of all animals is nor permitted), (2) a buffer area (fishing is permitted with traditional fishing gears, (3) a neighbouring fishing area (<20 >km), and (4) a fishing area off a neighbouring island. Two randomly selected sites were sampled within each management category and MR in October and March 2004.
