Growth curves and specific growth rate of Concholepas concholepas (Bruguière, 1789) (Gastropoda: Muricidae) in culture experiments

Abstract

The muricid Concholepas concholepas (Bruguiere, 1789) represents the most important gastropod fishery within its geographical distribution range, which extends from the central coast of Peru (6o 55’ S, 79o 52’ W) to the south of Chile (55o S, 68o W) (Alamo and Valdivieso, 1987). This species has been the subject of a significant number of publications (Castilla, 1988; Rabi et al., 1996), most of them relating to Chilean sites. Peruvian studies are scarce and some exist only as internal reports in fishery research institutions. C. concholepas is commonly known as loco in Chile and chanque or tolina in Peru. C. concholepas
