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

Concholepas concholepas makes up the most important gastropod fishery within its geographical distribution range. This species has been the subject of a significant number of publications, most of them relating to Chilean sites.The purpose of this paper is to estimate the growth parameters, albeit in a preliminary fashion, for Peruvian specimens in experimental culture conditions, and to determine the specific growth rate and the empirical production index based on the Specific Growth Rate (SGR). Length and weight data were grouped to estimate growth parameters (K and L) with the von Bertalanffy´s plot and a modification of the Gulland and Holt plot. The SGR was also calculated using weight at recapture. The estimated growth parameters indicate a faster growth rate in comparison with previous growth studies reported in other populations.
