The story comes from the Humane Society.
Gore and his guests at the weekend ceremony dined on Chilean sea bass - arguably one of the world's most threatened fish species.
Also known as Patagonian toothfish, the species is under pressure from illegal, unregulated and unreported fishing activities in the Southern Ocean, jeopardising the sustainability of remaining stocks.
The species is currently managed by the Commission for the Conservation of Antarctic Living Marine Resources, the body which introduced a catch and trade documentation scheme as an attempt to tackle illegal poaching of this species.
