Fish may not be the most popular dish in the land locked state of Colorado, but many people in an effort to eat healthier and more ethically become pescetarians. There are many health benefits to a marine diet, some fish will raise your high-density lipoprotein and they are also a good source of omega 3 fatty acids. But there are also risks in maintaining a pescetarian diet.
Some are health risks such as the high mercury levels and other pollutants. High trophic predators like sharks and king mackerel should be avoided because the pollutants become biomagnified to possible dangerous levels. There are local advisories that are updated regularly to reflect the fish that is safer to eat If you are fishing for your own meals.
Another risk is the popularity of mid-high tropic level fish such as salmon or tuna. The popularity of these species has resulted in overfishing. This has lead to a dependace on salmon fisheries. This has also led to an increase in less valuable fish which are currently being overfished to made high protein animal feed. This has the potential over many years to create dead zones around the world. Several dead zones already exist in the Gulf of Mexico, the Bohai Sea in China, even the Chesapeake Bay is displaying signs of degradation. So if ones diet relies heavily on high protein marine life, be sure to research what is safest and best for the habitat of these animals so that we can all have anchovies pizzas, and salmon dishes for generations to come.
