Summary

This study reports length–weight relationships and growth parameters for Chriodorus atherinoides from La Carbonera, a karstic tropical coastal lagoon on the northwestern coast of the Yucatan Peninsula, Mexico. A total of 667 specimens were collected between April 2009 and March 2010. The length-weight relationship obtained was W = 0.0034Lt3.22. This study presents the first estimation of the model parameters of the von Bertalanffy growth equation (L = 27.30 cm, = 0.76 year−1 and t0 = −0.178 years), the instantaneous total mortality (2.51 year−1) and the maximum length record (26.0 cm total length), which is greater than previously recorded.
