Sino Agro Food (SIAF), creators of the defunct Chinese land-based shrimp farm known as "megafarm" have suffered another major loss with their Tri-way operations, according to their latest financial report filed with the US Securities and Exchange Commission (SEC).

The company, which owns a little over a third of Tri-way, said in a financial report the COVID-19 pandemic caused all of its fish being raised in Tri-way's farms to die in 2020, resulting in a "complete write off" for its Aquafarm 1 facility, where it is raising the tropical marine species Pearl Grouper, as well as at its Aquafarm 2 site, where it is raising the Malaysian fish Empurau.
