New Records of Demersal Fishes in the Northwest of Mexico

D.S. Palacios-Salgado and A. Ramirez-Valdez

Bigeye bass Pronotogrammus eos and speckled scorpionfish Pontinus sierra were observed for the first time in the west coast of the Baja California Peninsula, Mexico, associated to soft bottoms and were captured as part of the by catch of the shrimp fishery north of Magdalena Bay. This finding provides the evidence of the presence of these species approximately 650 and 550 km farther north to that previously reported for Pronotogrammus eos and Pontinus sierra in the eastern tropical Pacific, respectively. Previous records of larvae of P. eos and juveniles of P. sierra on the west coast of Baja California peninsula, together with the adult individual records presented herein may indicate a gradual process of colonization by both species in the area. Morphometric and meristic data are presented and the possible causes of their occurrence in the northeastern Pacific are discussed.
