2 Reasons Why Australia Shoots Fish Into The Ocean

Why does Australia use a fish cannon to feed tuna in the ocean? Two main reasons: (1) Tuna literally can't survive on land - they use ram ventilation and must swim constantly to breathe, so they need offshore ocean pens. (2) The spinning cannon spreads sardines across a huge area, forcing the tuna to exercise while hunting, which builds premium sashimi-grade fat worth up to $10,000 per fish. #tuna #fishfarming #aquaculture #australia #sashimi #bluefintuna #fishcannon #fishing #seafood #marinelife
