What are some fun facts about fishing?

Answer 1

It’s impossible to buy a live Tuna. Although they are one of the mightiest fish in the ocean they die as soon as they are brought on board the fishing vessel. In fact, when they swim in the sea they will die almost instantly if they stopped swimming.

This is because Tuna breath through a process called Ram Ventilation. This mean they have to keep moving to let water flow over their gills, constantly supplying them with oxygen. This is even true when they are sleeping. They’re also one of three species of fish, Tuna, Opah, and mackerel sharks that can maintain a temperature higher then the surrounding water.
