Why are fish aggregating devices FADs a problem?

The main concerns of campaigners such as Obaidullah are that FADs assist fishing of populations that are already over-fished, such as tuna, and that they can attract endangered animals, such as turtles, which are then taken up along with the targeted species — a consequence known as ‘bycatch’.

Why is fish farming an issue for wild populations genetically?

Since farmed fish often have been bred via selective breeding they have a lower genetic variation than wild fish. If they interbreed with the wild fish it can result in a less genetically diverse, and therefore less robust, population.
