CSB#6:Fish Farms
A lower amount of fish are coming from the wild, instead, people are receiving their fish by fish farming, or aquaculture. However, fish farms are usually crowded with fish in a small area, allowing diseases and parasites to easily infect the entire population of fish. Also, if an infected fish escapes into the wild, it can spread the disease to native species. Other fish would also be required to be killed in order for the farmed fish to be fed. However, fish farm owners discovered that these fish only require the same amount of food as their weight, this way, the prices of the farmed fish would be cheaper than the ones caught from the wild. Also, fish farming can be more efficient. Farmers can decide whether or not the fish are big enough to be sold on the market, the small fish can still grow. However, when big fish fleets start to set out their nets, they are most likely to receive the wrong species, dead fish due to the harsh fishing techniques or to small.

I found this article interesting because it shows the pros and cons of aquaculture. I believe that fish farming is a great way to receive fish because they are efficient. This way, more fish would not go to waste, which would increase the population of wild fish. However, some people would be unsure about the safety of the fish since they may contain diseases due to the their cramped living conditions.
