Rábago-Quiroz C.H., García-Borbón J.A., Palacios-Salgado D.S., Barrón-Barraza F.J. 2017. Length–weight relation for eleven demersal fish species in the artisanal shrimp fishery areas from the Bahia Magdalena-Almejas lagoon system, Mexico. Acta Ichthyol. Piscat. 47 (3): 303–305.
The length–weight relations (L–W) for 11 demersal fish species from a lagoon system in south-western coast of the Baja California Peninsula, Mexico were estimated. The following species were studied: Occidentarius platypogon (Günther, 1864); Balistes polylepis Steindachner, 1876; Diplectrum pacificum Meek et Hildebrand, 1925; Paralabrax maculatofasciatus (Steindachner, 1868); Eucinostomus gracilis (Gill, 1862); Eucinostomus dowii (Gill, 1863); Etropus crossotus Jordan et Gilbert, 1882; Etropus peruvianus Hildebrand, 1946; Haemulopsis axillaris (Steindachner, 1869); Orthopristis chalceus (Günther, 1864); and Orthopristis reddingi Jordan et Richardson, 1895. These species were caught in the artisanal shrimp fishery areas from the Bahia Magdalena-Almejas lagoon system; thus the specimens were obtained with the shrimp trawl net. A total of 3824 specimens were used to estimate parameters of the relations. The slope (b) fell within 2.7 to 3.4 and the growth pattern was isometric in most cases (10 species), whereas for one species the growth was allometric. The L–W relation parameters for Occidentarius platypogon and Eucinostomus peruvianus, are not available in FishBase.
