Secrets of the Superhuman Food Pyramid: Negative Effects of Farmed Fish

Farm fishing’s roots can be traced back to the early 1700s when a German farmer was able to effectively gather, fertilize, hatch, and grow fish from mere eggs. Since then, the method has been replicated around the world in countries like Japan, the United States, Canada, Chile, and Norway, to name a few. The practice entails raising fish in large tanks situated inland or in enclosures or nets in shorelines and even in the open ocean. Though this method appears sustainable at first glance, it in fact has manifold negative effects which is why we recommend that you steer clear of farmed fish at all costs.

Farmed Fish Risks:

Farmed fish may be a potent source of essential fatty acids omega-3, but there is a downside to this. Bear in mind that farmed fish are fed commercially manufactured fishmeal, most of which are fortified with fish oils so as to boost the omega-3s in the subsequent fish harvest. The fish oils that are often used in farm fishing have typically been made without following strict harvest, production, and post-production handling standards.

Adding fish oils that have been crudely manufactured does more harm than good. In fact, this practice of fish oil fortification increases the levels of polychlorinated biphenyls or PCBs in the subsequent fish harvest. PCBs are chemicals that have been banned for use in the United States since 1976 but to this day threaten human and animal health. Exposure to PCBs may cause the development of diabetes as well as cancer. PCBs are neurotoxic as well and have been found to cause brain defects in infants and children.

The method by which farmed fish is produced causes severe environmental harm as well. Take for instance tuna farm fishing. This fish is a carnivore, which means it can only be fed wild fish, and it takes about 20 kilograms or 44 pounds of smaller anchovies, mackerel or sardines to produce a kilogram of tuna. Allotting such considerable resources to produce very little subsequent harvest is not only economically unsustainable, but the practice threatens worldwide supply of fish as well as endangers the food source of manifold species in the marine food chain.

Fish farming, especially in the case of salmon farming, poses risk to wild salmon survival as well. As it turns out, sea lice are prevalent in ocean waters where salmon farms are. Since salmon farms are situated along routes where wild salmon smolts pass, the latter getting infected with these parasites are always a certainty, subsequently endangering the population of wild salmon.

Farmed fish typically live in disease-stricken environments as well. Because thousands of fish are crammed in a limited space, they then live within their own filth and within tons of uneaten fishmeal, perfect opportunities for pathogens to accumulate. To combat pathogen infestation, producers then feed the fish with antibiotics. Not only does this increase the risk of environmental pollution, these pathogens may end up becoming resistant to antibiotics, too. These pathogens may transfer to humans by way of the latter’s farmed fish consumption as well. Worst, the likelihood of bringing about antibiotics resistance in humans is a big possibility, too.
