Aspects of the ecology and growth of an intertidal juvenile population of Concholepas concholepas (Mollusca: Gastropoda: Muricidae) at Las Cruces, Chile

The habitat, density and growth rate for an intertidal population of Concholepas concholepas (Bruguiere, 1789) were studied at Las Cruces, Chile (Lat. 33 degree 30'S; Long. 71 degree 38'W) during 1977-1978. The growth rate (3.67 mm month super(-1)) was determined in a newly settled group,...

Description
Summary:The habitat, density and growth rate for an intertidal population of Concholepas concholepas (Bruguiere, 1789) were studied at Las Cruces, Chile (Lat. 33 degree 30'S; Long. 71 degree 38'W) during 1977-1978. The growth rate (3.67 mm month super(-1)) was determined in a newly settled group, whose average length was 11.3 mm, and whose age was estimated at 3 months. The densities found ranged between 1.1 and 107.3 "locos" m super(-2). Based on these results, the time of settlement of C. concholepas was calculated; capsule deposition, maximum maturity and recruitment reported by other authors for different localities are discussed.
