Over the last few years I have seen a flood of cheap, frozen Tilapia, farm raised in the poison water of china........
When it first came out here it was from the Philippines but I found they were hiding the sources so I stopped buying it......
How feasible is sourcing local??
Very. And sustainable. There are sites like this : https://localcatch.org/, and others, apps etc. If one wants local, it is there. One of the best ways though, if you around the water, is to speak with the local fishermen. Show an interest in what they do and how they do it. You will probably not only make a friend for life, you will more than likely get the freshest seafood possible without any middleman markup.
