Summary The present work analyzes the relationship between length and weight for 28 fish species belonging to 16 families in Celestun lagoon, a natural marine reserve located in southeast Mexico that is influenced by freshwater seeps. With interrupted periods, a total of 14 846 specimens were collected from 1990 to 2006. The most abundant species were Eucinostomus argenteus , Eucinostomus gula , Anchoa mitchilli and Lagodon rhomboides . Exponents varied around b = 3.17 at P < 0.001, indicating a preference for isometric relationships. This study presents the first estimation of LWR for four species ( Menidia colei , Lucania parva , Floridichthys polyommus , Garmanella pulchra ) and the maximum length record for F. polyommus (19.5 cm standard length) that is greater than previously recorded.
