MetadataShow full item record
The species of the Genus Merluccius present in argentine waters, Merluccius hubbsi and M.polylepis are similar externally and it is very difficult to separate them in the capture. Knowing the importance of both species from the commercial point of view, and the need of a correct identification, some morphological characteristics have been compared, looking for external differences, useful for the identification on board. The samples have been taken from the total area of distribution of both species in argentine waters. A total of 154 specimen of Merluccius hubbsi and 105 of M.polylepis were analyzed.
