the current status of the population is unknown... but likely is at sustainable levels.

But, like Black Seabass, threshers are susceptible to overfishing.

Sharks are known to live for a long time. They are slow to grow, have very few babies, and don't reach reproductive maturity until about 4 years old. Harvesting young pups and large breeders are two things that could have a negative impact on their long term sustainability.

Thresher sharks are also known as ram ventilators, which means they have to be swimming forward in order to breath. This is a problem because many times they get hooked in their tails. Threshers like to hit their prey with their tails to stun them. This results in tail hooking and during the fight, the sharks are dragged backwards through the water. As a result, many sharks are fought to the point of exhaustion, and when released, some do not survive.

Many people feel that recreational sport fishing pressure on threshers has increased in recent years due to the sharing of current fishing reports on the internet, and the fact that thresher sharks are very easy to hook. The possible results from an increase in recreational fishing pressure have not been studied.

The are no regulations on sharks fishing currently. That means you can keep as many as you want, of all shape and sizes. That doesn't mean that you should.

There are many reasons why keeping threshers is controversial, and many reasons why some sort of regulation may be implemented. Most reasons are based on the biology and life history of the animal.
