I would buy wild caught with no issues. I also legally/commercially collect fish and other marine life native to Florida and the Caribbean. Most wild caught fish (ones I catch included) are caught with sustainably in mind. Native collectors for most fish are more aware of populations than anyone and respect that. What is the point of collecting and just phasing out your income, as you over collected. There are also strict rules and regulation in place (in most places) to also keep people in check.
Our collection of wild fish is a drop in the bucket compared to commercial fishing for the food industry. For example, Hawaii does not permit collection of fish for the Aquarium Trade, yet collection for food is still allowed. Most tangs in Hawaii are unregulated, outside of a daily bag limit. This means no minimum size, maximum size or slot for the fish. With that in mind, think of it this way; a typical fisherman will take the largest fish they can get and take as many as the bag limit allows. By doing this, they are taking the breeding stock. Most aquarium collectors take the smaller fish, as it is easier/cheaper to collect/ship. While yes, they are taking the smaller fish, most smaller fish do not grow up to be adults. So which one is doing more harm?
In the end, wild caught fish collected sustainably is a nice income for locals and has minimal impact on the population. All while commercial fishing for food seems to cause more damage, as the breeding stock is typically collected.
While I see that either can be considered bad, the Aquarium trade has the least effect on the population of most fish. Now, if you do remove collection for the aquarium trade, it will benefit the population to an extent. My issue is the ban of aquarium collection of marine fish, but no changes to the collection for food. If they were smart, they would adjust both to allow for X number total harvested by either method each year. Not ban one and not changes the regulations for the other. This benefits all involved. Taxes, licenses, fish management, etc.
Just my .02 cents, as I guess I am a bad person, since I collect wild fish and other marine life as well.
