Fish farming, which is more commonly known as aquaculture, is a common practice all over the world and makes up a very large portion of the food industry. In fact, it’s estimated that one of every four fish consumed was bred on a fish farm. However, new reports are indicating that the salmon raised on fish farms is laced with far more toxic chemicals than their wild brethren. Just what this may mean for human health is murky, given that the risk appears to be small and that the health benefits of eating salmon, whether farm-raised or caught in the wild, are thought to be considerable. This, is just one single illustration of the hidden risks farmed fish may entail. Still, aquaculture is necessary for keeping up with the demand of a seafood-loving world and comes with an assortment of advantages and disadvantages. 

Firstly, it is undeniable that fish farming allows us to replenish the food fish supply at a faster rate than the oceans can produce it, allowing suppliers to keep up with demand. In our globalized world, a supply at a larger scale is a need no there seems to be no other alternative when it comes to supplying all supermarket all over the word. 

The aquaculture industry has created as well numerous jobs for people who reside in impoverished areas where unemployment is rampant. It’s highly prevalent in Asia, where it provides thousands of jobs. This process demands man power and thus, gives employment opportunities. For producers, on the other hand, this serves as a source of income since seafood is highly demanded commercially and delivered not only locally but also to other countries.

Another bright side to the matter comes along with nutritional provisions. Seafood is typically loaded with protein, omega-3 fish oils and other nutrients that are highly beneficial to impoverished areas. Fish farming can increase the supply of fish available for these regions, fighting malnutrition.

Opponents of the practice of aquaculture argue that fish farms consists of large amounts of fish condensed into a single area. When these fish excrete waste or die, they’re released into local water sources, polluting and contaminating them.

Fish raised on farms need feed, with much of their feed consisting of fish meal. This fish meal consists of ground-up smaller fish usually caught in the open ocean. Unfortunately, the resources required to feed the fish typically outweigh what is produced. For example, according to the San Francisco Chronicle, it takes about 26 pounds of fish meal to create one pound of Bluefin tuna, making many farms extremely inefficient.

Critics of aquaculture say that despite the good intentions of culturing fish for consumption and increase the population of fish, it can also lead to the increase population of invasive species that are harmful to the other marine species because they take away the food supply for fishes in the wild. The Janitor fish, for one, is considered a threat to other freshwater species since they breed faster and compete with other fishes for food. What’s more, because of the large numbers of fish contained in fish farms, they can be breeding grounds for bacteria, sea lice and various diseases. If fish escape into the wild ecosystem, which is inevitable with such large numbers, these diseases may rapidly spread.

At this stage aquaculture will continue to be popular in many countries especially with the growing demand of commercial fish products. Although there are drawbacks to this industry, there have also been developments to mitigate the concerns brought about by aquaculture.
