ABSTRACT In the Southeast of Mexico, there are many native cichlids with commercial interest such as redhead cichlid (Vieja melanurus) and twoband (V. bifasciata), which have a great local demand excellent meat quality. However, it is necessary to implement their culture based on nutrition studies digestive biochemistry. This study’s objective was characterize these two cichlids’ proteases (pH,...

Reef habitats of the tropical Atlantic are separated by river outflows and oceanic expanses that may preclude larval dispersal or other population connections in shorefishes. To examine the impact of these habitat discontinuities on the intraspecific phylogeography of reef-associated species we conducted range-wide surveys of two amphi-Atlantic reef fishes that have dispersive pelagic larval st...

We used complete sequence of the mitochondrial cytochrome b gene to test monophyly of the Sparoidea, Sparidae, six subfamilies of Sparidae, and to elucidate the interrelationships of the 33 recognized sparid genera. The analysis included 40 sparid species, 10 closely related species, 10 basal percoids, and two nonperciform outgroup species. The aligned 1140 base pairs of cytochrome b yielded 54...
