The world's population is expected to reach 9.3 billion people by 2050 and if we continue our consumption of fish at the rate we are going we will completely deplete our fish stock by 2020. Steps need to be taken in order to prevent this situation considering that fish is the main source of protein for people in developing countries. One way to prevent this is to put more time and energy into fish farming to make it the most sustainable practice it can be.
The are many factors associated with open-net pen fish farming that are not sustainable and need to be addressed such as overnutrientalization, escapes, particulate pollution and welfare of the animals around the cages. If all of these problems were to be addressed using better management and regulation then this could have potential to be the most sustainable practice for producing fish.
