Description
- The Bigeye Tuna are a dark metallic blue on their with a white underbelly and yellow dorsal fins. They can grow to reach a length of 6.5 feet long and can weigh up to 450 pounds. The Bigeye Tuna have a short lifespan of only 7 to 8 years and they start to reproduce when they are 3 years old.
- You can find Bigeye Tuna in the Atlantic, Pacific, and Indian oceans. They are more ample in population in the western and Eastern Pacific and you will not find them in the Mediterranean.
Role in the Ecosystem and in our Economy
- Bigeye Tuna are a valued fish in different fish markets all around the world. They give many people livelihoods to a great deal of people and play a vital role in the economy of many areas worldwide.
- The Bigeye Tuna also play a key role in the oceans ecosystem, because they are a top predator in the food chain, meaning they keep many other fish populations in check.
Cause of Decline
- The Bigeye Tuna are very prone to over fishing since they are such a desired fish around the world. Bigeye Tuna are not yet endangered, but they are vulnerable and if we do not keep commercial and domestic fishing rates down, we will see a decline in their population. Juvenile Bigeye Tuna are also being frequently caught as bycatch which can dramatically cut the population if too many juveniles are killed.
What the WWF is doing
- Today the WWF works with the government and regional fisheries to make Bigeye Tuna a sustainable business by advising new plans that reduce bycatch and pirate fishing.
What can you do?
- The most important thing you can do is support the WWF and donate to help their cause and if you happen to be out on the ocean during a fishing trip, try not to catch to many Bigeye Tuna.
