Gunpowder Fishing

While playing Sea of Thieves on a random crew, one of the players mentioned that you can use a gunpowder barrel to blow up a school of fish off the islands. Supposedly this will spawn in several fish that you can then pick up and add to your inventory.

That being said I did some google searches for this, but haven’t found any results to confirm this. Can anyone else confirm that this functionality is legit?
