The Top Toad Notie, also known as the Patagonian Toothfish (Dissostichus eleginoides), is a deep-sea species prized for its rich, buttery flesh and marketed as "Chilean sea bass" in culinary circles. This large, slow-growing fish inhabits the cold, deep waters of the Southern Ocean, particularly around sub-Antarctic islands. The primary fishing nations harvesting the Patagonian Toothfish are Chile and Argentina, which operate in the South American sector, as well as Australia, France, and the United Kingdom, which manage fisheries around their respective sub-Antarctic territories such as Heard Island, Kerguelen Islands, and South Georgia. The industry is strictly regulated by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to combat illegal, unreported, and unregulated (IUU) fishing, ensuring the sustainability of this valuable species.
