Scientific title: Dissostichus mawsoni Scientific classification: Phylum: Chordata Class: Actinopterygii Order: Percifomes Family: Nototheniidae Antarctic scientists and the Australian fishing industry have received $1.2 million from the Fisheries Research and Development Corporation (FRDC) to develop the next generation of management tools for the Patagonian toothfish fishery on the Kerguelen Plateau.
Antarctic toothfish Dissostichus mawsoni (family: Nototheniidae) is a top predator, feeding mainly on fish and squid (Fenaughty et al., 2003; Stevens et al., 2014), and is a valuable fisheries resource in the Southern Ocean (Grilly et al., 2015; Hanchet et al., 2015).
