Length–weight (LWR) and standard length–total length (L–L) relations are presented for 14 fish species caught in four estuaries from the south-eastern coast of Michoacán, México (Central Pacific): Lile nigrofasciata Castro-Aguirre, Ruiz-Campos et Balart, 2002; Pliosteostoma lutipinnis (Jordan et Gilbert, 1882); Agonostomus monticola (Bancroft, 1834); Mugil curema Valenciennes, 1836; Poecilia butleri Jordan, 1889; Centropomus nigrescens Günther, 1864; Lutjanus novemfasciatus Gill, 1862; Eucinostomus currani Zahuranec, 1980; Dormitator latifrons (Richardson, 1844); Eleotris picta Kner, 1863; Gobiomorus maculatus (Günther, 1859); Awaous banana (Valenciennes, 1837); Gobionellus microdon (Gilbert, 1892); Trinectes fonsecensis (Günther, 1862). Values of b ranged from 2.912 to 3.432. The results revealed that length–weight relations for all species were highly correlated; likewise, length–length relations for all fishes also showed high correlation. This study presents for the first time, length–weight parameters for two species and length–length relations for six species.
