Length-weight relationships for selected fish species from a coastal lagoon influenced by freshwater seeps: Yucatan peninsula, Mexico

Abstract

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.

Length-weight relationships and growth parameters of two endemic fish species (Floridichthys polyommusHubbs, 1936 andFundulus persimilisMiller, 1955) from the Yucatan Peninsula, Mexico

“…The exponent b close to the isometric value was also obtained for F. polyommus (Vega‐Cendejas et al., ). No previous reports of LWR for F. persimilis have been published.…”

“…The maximum SL recorded for F. polyommus in this study was 80 mm. This figure differs from the maximum SL reported elsewhere for this species: 195 mm SL in Celestun Lagoon (Vega‐Cendejas, de Santillana, & Arceo, ); 91 mm SL in Ría Lagartos, Yucatán (Peralta‐Meixueiro & Vega‐Cendejas, ); and 103 mm SL in La Carbonera, Yucatán (Badillo‐Alemán, Bonilla‐Gómez, Tzeek‐T, Gallardo‐Torres, & Chiappa‐Carrara, ). The differences in SL between Champotón River and Celestun Lagoon may be due to that Celestun is a meso‐eutrophic coastal lagoon that is highly productive throughout the year, with a substantial contribution to productivity by macroalgae and seagrass (Herrera‐Silveira, Medina‐Gomez, & Colli, ).…”

“…This finding was also observed by Vega‐Cendejas et al. () in Celestun Lagoon ( b = 3.31) and Badillo‐Alemán et al. () in La Carbonera, Yucatán ( b = 3.55 males; 3.38 females).…”

Length–Weight Relations of Eight Fish Species from a Small Caribbean Coastal Lagoon, Mexico

“…For H. humeralis we found statistical differences with previous reports (Froese and Pauly 2012) with the estimates produced by SMA method only, while for F. polyommus the estimates provided here are lower than those reported by Vega-Cendejas et al (2012), although the statistical differences are only appreciated with OLS estimates. In this last case, differences in size, physiological conditions, and other biological and sampling factors between our specimens and those previously reported may explain the discrepancy in the estimates.…”
