Growth and mortality of Sphoeroides testudineus (Tetraodontiformes: Tetraodontidae) in a tropical coastal lagoon in northwestern Yucatán Peninsula Crecimiento y mortalidad de Sphoeroides testudineus (Tetraodontiformes: Tetraodontidae) en una laguna costera tropical en el noroeste de la península de Yucatán

Abstract

This study reports growth parameters and mortality for Sphoeroides testudineus from La Carbonera, a karstic tropical coastal lagoon on the northwestern coast of the Yucatán Peninsula, Mexico. A total of 461 specimens were collected between April 2009 and March 2010. We obtained the length-weight relationship and the growth parameters of von Bertalanffy growth model (VBGM) by length frequency analysis. Additionally, mortality was estimated and analyzed. Exponent b indicated an isometric growth pattern. The growth parameters of VBGM were: L∞ = 29.50 cm, k= 0.77 year-1 and t0= - 0.168 years. The instantaneous natural mortality was 1.53 year-1.Este estudio reporta parámetros de crecimiento y mortalidad para Sphoeroides testudineus de La Carbonera, una laguna costera cárstica tropical en la costa noroeste de la península de Yucatán, México. Un total de 461 ejemplares se recogieron entre abril de 2009 y marzo de 2010. Se obtuvo la relación talla-peso y los parámetros de la ecuación de crecimiento de von Bertalanffy mediante el análisis de la frecuencia de tallas. Adicionalmente, se estimó y analizó la mortalidad. El exponente b indicó un patrón de crecimiento isométrico todo el año. Los parámetros del modelo de la ecuación de crecimiento de von Bertalanffy fueron: L∞ = 29.50 cm, k= 0.77 año-1 y t0= - 0.168 años. La mortalidad natural instantánea fue 1.53 año-1.
