Comparative growth performance of horse mackerel of the genus Trachurus, with emphasis on T. symmetricus murphyi in Chile
L. Cubillos and H. Arancibia

This contribution presents von Bertalanffy growth parameter estimates for various species/stocks of horse mackerel of the genus Trachurus from around the world, and compares these with growth parameters for T. symmetricus murphyi caught off central-southern Chile (33ºS-39ºS). It is found that Trachurus stocks inhabiting upwelling areas such as the Humboldt and Benguela current systems grow better than their ecological equivalents in temperate waters, such as the North Sea. The von Bertalanffy growth parameters estimated for the Chilean horse mackerel are: FL = 65.2 cm (TL = 71.6 cm) and K = 0.138 year-1.

Keywords: Horse mackerel, Trachurus, growth, central-southern Chile.
