Are tuna populations declining?
Bluefin tuna populations have declined severely from overfishing and illegal fishing over the past few decades –not just Atlantic bluefin tuna, but also Pacific bluefin tuna and Southern bluefin tuna. Population declines have been largely driven by the demand for this fish in high end sushi markets.
What happens if there is no more tuna in the ocean?
The decline of tuna populations could threaten food supply chains and jobs around the world, as well as potentially destabilising the underwater food web, Coulter said. “Tuna are both predators and prey. They eat smaller fish and invertebrates and are a food source for larger marine life, such as sharks and whales.
What happens if tuna goes extinct?
If bluefin tuna were to go extinct, it is likely that these sea creatures would quickly become overpopulated. What is this? This would cause a sort of domino effect as the increase in numbers of these animals would lead to a decrease in the populations of their prey.
