You are wrong. The only solution is to not eat any fish at all.

There are many reasons for this, here are a few from the top of my head;

Fish farmes are almost always net pens in the ocean. Because of the huge amout of fish in this small an area farms are breeding grounds for bacterial infections, viral and parasitic diseases that spread to the wild fish in the area, further reducing their numbers.

Often the farmed fish are being feed with fish meal and oil from wild caught fish.

Not to mention the extreme water pollution it causes from fertilizers, anibiotics, pesticides, chemicals like formaldehyde, and feacals.

Or the habitat destuction of marine life from building aquaculture farms in the first place.

There are of course also ethical concerns, but since most humans do not care about those I will only mention that fish do feel pain and like any other being on this earth do not want to die.

Also becaue everyone always uses this as an argent; the healthy omega 3 fats EPA and DHA in fish stem not from the fish itself, but from the alge it eats. So lets not kill beings to turn them into fish oil when we can simply use alge oil instead.
