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