Purse Seine Fishing

What is Purse Seine Fishing?
How does Purse Seining harm the ecosystem?
Sea turtles can be captured by a purse seine as it is set and then become entangled in the net mesh as it is hauled in. Entangled turtles may sustain injuries to their flippers and shells due to the force of the net as it is hauled. encircled marine mammals cannot escape and can become entangled, injured, or stressed. In U.S. fisheries, species most commonly captured include bottlenose dolphins and humpback whales.

Does the government regulate Purse Seining?
What would happen if the government banned Purse Seining?
The fishing industry is a large business and purse seining is a very common method to fish. If the government banned this method, the ability to capture large amounts of fish wouldn’t be possible. On the other hand, there would be less bycatching and allow endangered species to thrive.
How do we find a solution?
Is Purse Seining environmentally sustainable?
In moderation and on certain species, this method is sustainable. Large schools of tightly schooling fish can be caught with almost no bycatch or impact on total population. Problems arise when this method is used on any other species: purse seining is used on bluefin tuna (who aggregate to spawn), decimating their fairly small population.
