Trace elements in the silky shark Carcharhinus falciformis in the Central Pacific Mexican Shelf.

Mercury (Hg), cadmium (Cd) and copper (Cu) concentrations were determined in muscle, liver and fin of the silky shark (Carcharhinus falciformis) caught in the Central Pacific Mexican Shelf. Liver tissue presented the highest concentrations of Cd (2.83 μg g wet weight (ww)) and Cu (2.

First report of partial albinism in the blue lobster (Bouvier, 1895) from the Mexican Pacific (Crustacea, Decapoda, Palinuridae).

The first case of partial albinism registered in the Mexican Pacific by the blue lobster is presented. The specimen was collected on the southern coast of Jalisco know as Punta "El Estrecho".

[Analysis of diet composition and overlap in four species of the genus Diplectrum (Perciformes: Serranidae) in the Mexican Central Pacific].

Analysis of diet composition and overlap in four species of the genus Diplectrum (Perciformes: Serranidae) in the Mexican Central Pacific. The information of trophic interactions among species is essential to understand ecosystem function. To assess this in four Diplectrum species, we analyzed the stomach contents of 397 individuals caught using shrimp trawling nets off the coasts of Jalisco and Colima, Mexico.
