Characterization of first blastomeres in Patagonian blenny (Eleginops maclovinus) (Perciformes: Eleginopidae).

SummaryThere is no information about the characteristics of early cleavage in the Patagonian blennie (Eleginops maclovinus), which can be used as a diagnostic tool for embryo quality. The purpose of this investigation, therefore, was to characterize the first blastomeres of E. maclovinus morphologically.
