Life-history traits of the Magellan plunderfish Harpagifer bispinis (Forster, 1801) in the Beagle Channel (Tierra del Fuego, South America)
The Magellan plunderfish Harpagifer bispinis is a small and benthic sub-Antarctic notothenioid commonly found in shallow waters of the Beagle Channel, whose biology is poorly known. Based on a seasonal sampling conducted throughout a year, we provide original data on some biological parameters, such...
