Fish farming is a hot topic in some fields. Environmentalists often criticize the impact of fish farms on the environment, while supporters point out that fish farms are an important source of high-quality protein. No matter how you look at this issue, one of the great advantages of fish farming is that it is a good entrepreneurial opportunity.

List of Pros of Aquaculture

1. Potential to Feed Large Populations
As the population grows, so does the demand for food sources, especially protein sources. Although this demand can be met by catching wild fish, it is actually slowly depleting marine resources. Nature cannot catch up with human fishing speed, which makes many species endangered.

However, fish farms are designed to be more efficient than wild fishing. Because farmers can control water quality, limit the threat of predators, and feed the fish according to their own schedule, they can produce and harvest more fish. With this technology, humans will be able to feed more people while supplementing the number of natural fish.

2. Source of Income
Aquaculture provides livelihoods for fishermen and others because it provides employment opportunities. Fish farmers usually use fish tanks and cages in the middle of the ocean to raise fish. There are also fish producers who use cages for breeding in ponds and lakes. This process requires manpower and therefore also provides employment opportunities. On the other hand, for producers, this is a source of income because seafood is in high commercial demand and can not only be consumed locally, but also can shipp to other countries.

3. Potential Health Benefits
Eating fish has many health benefits. Fish contains omega-3 fatty acids, which are believed to prevent heart problems. Some studies have also shown that a fish-based diet may help prevent diseases such as colon cancer. By raising fish, more people can include fish in their diets and get the benefits of a large fish diet.

List of Cons of Aquaculture

1. Propagation of Invasive Species
Critics of aquaculture say, although the original intention of farming fish for consumption and increasing the number of fish is good. But it can also lead to an increase in the number of invasive species harmful to the ocean, because they deprive wild fish of the food supply.

2. Environmental Concerns
People’s biggest concern is whether fish farming will damage the environment. I just mentioned that fisheries can replace overfishing and deplete marine resources, but this is only true to a certain extent. Large fish, such as salmon, feed on small fish such as anchovies. This means that we still need to consume a lot of wild animals to produce one certain fish.

There are also concerns about pollution. The fast-growing fish population also produces a lot of waste, which can pollute water quality. Any form of pollution will threaten the marine ecosystem. This means that fish farmers must come up with creative solutions to limit these pollution.

3. Potential Health Concerns
Some people worry that artificially farmed fish will not bring the same health benefits as wild-caught fish, and may even bring some health risks. Because the spread of diseases in fish farms is much easier than in the wild, this may pose risks to humans.

Most farms use drugs or antibiotics to treat fish or prevent diseases. However, we don’t know how this will affect those who consume them.
