The meat-free brand, who recently announced it was struggling to keep up with the 'scorching demand' of its products, claims its platform 'has never been burger-specific' - despite the popularity of its plant-based patty.
'A collapse of biodiversity'
"We're continuing to invent and discover the capabilities and tools for the whole range of meat and dairy products from plants," the report reads.
"Plant-based fish is a particularly high priority, as marine harvesting has decimated underwater populations and is leading to a collapse of biodiversity in oceans, lakes, and rivers."
Impossible Foods has not, however, announced any plans about releasing a plant-based alternative to fish.
Impossible Foods itself consider its meatless patty to be plant-based rather than vegan.
This is because in 2017 a key ingredient - soy leghemoglobin (heme) - from the brand's flagship item the Impossible Burger was fed to rats in order to test its safety. In excess of 180 rats were killed as a result of the testing.
CEO Pat Brown reacted to the controversy, publishing a statement titled The Agonizing Dilemma of Animal Testing.
