Growth and mortality of Sphoeroides testudineus (Tetraodontiformes: Tetraodontidae) in a tropical coastal lagoon in northwestern Yucatán Peninsula

Resumen

This study reports length-weight relationships and growth parameters for Sphoeorides testudineus from La Carbonera, a karstic tropical coastal lagoon on the northwestern coast of the Yucatan Peninsula, Mexico. A total of 461 specimens were collected between April 2009 and March 2010. We obtained the length-weight relationship and the parameters of the equation of growth von Bertalanffy by length frequency analysis. Exponent b varied around 2.978, indicating an isometric growth pattern. The model parameters of the von Bertalanffy growth equation were: L_∞ = 29.50 cm, k = 0.77 year^-1 and t₀ = - 0.168 years.
