All lifeforms in these systems are ultimately dependent upon all of the other creatures in these ecosystems, with each one playing an important and unique role. The fast decline of the fish population means that there is an unbalance in the marine ecosystem. Looking at this scenario, it does not seem far-fetched to think that farm fishing could solve the problem of overfishing. Overfishing affects most of the world’s fish stocks. One of the main causes of overfishing is that there is too much fishing capacity.
