Why are fish farms open?

Fish farmers are starting to open “on land” fish farms that eliminate any chances of diseases spreading in the ocean. Scientists are also finding new ways to filter water and keep farmed fish in a contained, clean environment so antibiotics are not required.

Why is aquaculture important?

Aquaculture (neat, huh?) will become vitally important in the near future to keep up with demand. Though industrial farming gets a lot of slack across the board, fish farming may be our answer to fulfilling the animal protein needs of the world’s growing population.

What percentage of the world’s protein is fish?

Did you know fish accounts for 17 percent of the world’s protein intake? That may not seem like a lot, but by 2050, farmed fish production is expected to more than double to meet global demands. Fish are the most environmentally-friendly animal protein to produce, efficiently converting feed into meat while generating a fraction of the greenhouse gasses of livestock production. But as it stands now, our earth’s rivers, lakes, and oceans are fished to their limits.

Which animal is the most environmentally friendly?

Mollusks, like clams, oysters, and scallops, are the most environmentally-friendly source of animal protein, as they don’t use freshwater and they serve to clean the environment around them. Fish play a key role in fulfilling the protein needs of the world population.

Do farmed fish eat other fish?

In some cases, farmed fish eat other wild fish, negatively impacting the ocean ecosystems; in other cases they are fed pellets, which may not adequately meet their nutritional needs, and result in fattier, less nutritious, and less flavorful fish.

How does fish farming affect the environment?

Water pollution. Fish farming also contributes to water pollution to a certain extent. All kinds of waste products related to aquaculture are often just disposed into the nearby ocean. In turn, feces and other unpleasant components are released into the open sea, which leads to a degradation of the overall water quality.
