Get Informed The Truth Is In The Can Tweet
By Taja Allen
The truth is in the can-the tuna can that is.
Conventionally, large non-specific fishing nets are dragged through the ocean to catch tuna. Since conventional tuna fishing is non-specific many other organisms are the victims bycatch. Bycatch is the word used to describe any organism that is unintentionally caught. In many cases the bycatch organisms are other species of fish, sea turtles, sharks, and dolphins. You’re probably thinking, “Well can’t they just let the bycatch go?” In some cases yes, but the tuna fishing nets are dragged until they are full. This means air-breathing animals like the sea turtles and dolphins are unable to obtain oxygen and die before the nets are pulled up.
To reduce bycatch, shop for canned tuna that are labeled troll, pole, or hand line-caught. Also, if you’re worried about mercury levels, purchase skipjack, yellowfin, or albacore tuna. These three tuna species are smaller and have lower levels of mercury. Remember, mercury content rises with tuna size and age. Also, don't forget to recycle all used tuna cans!
