Can speckled seatrout be used for sushi?

I never see this on the menu anywhere. I can catch these pretty easily, and if I have a freezer that can get everything to the right temperatures for sushi, can it be used?

To be clear, even though "trout" is in the name, this is not a salmonid. It is a drum fish that is found in saltwater in the SE United States.

Just not sure why it isn't more common.

Thanks!
