BLUEFIN TUNA

Bluefin Tuna is the largest tuna and can live up to 40 years. (WWF) As they migrate across the ocean, they are built for speed with their flexible fins. Being at the top of the food chain, they are the top predators from the time they hatch. With their extreme vision, they search for fish such as herring, mackerel, and eels, throughout their lifetime. The Bluefin Tuna splits into 3 different species: Atlantic, Pacific, and the Southern. Out of these three, the Atlantic Bluefin Tuna has the most endangered status. (WWF)

THE ISSUE

The population of Bluefin tuna has been reduced by a dramatic rate where 96% has dropped. (The Guardian) Approximately more than 9 out of 10 of the species that were caught were too young to have reproduced, meaning they may have been the last generation of the bluefin tuna. (The Guardian) Amanda Nickson from the Pew Environment Group has stated that as they are “highly valuable natural commodities”, many restaurants and industries want them since the Bluefin Tuna gives them high returns. Out of these industries, the most predominant fish fleets were stocks from Japan, Mexico, South Korea, and the US.

The Atlantic bluefin is a highly desired product in the fish market in Asia—a single fish has sold for over $3 million. (NYTimes) As they are so desirable, fishermen use even more processed methods to catch tuna, which leads to an instant decline in the population. As they are at the top of the food chain, they are responsible for sustaining the balance in the ocean environment, and with the decline, the entire ecosystem can be disrupted.

    Great presentation Ingrid. I like your focus on the importance of consumer choice. What can we do other than just not buy tuna? Are there some types of tuna that are ok to eat?
