One of those environmental pollutants is methyl mercury, found in varying degree in different kinds of fish.
Mercury has been linked to an increased risk of having a heart attack, while omega-three fatty acids also found in fish...decreased the risk.
Researchers say to eat fish 2-3 times a week, but avoid predatory fish that contain the most pollutants like pike, perch, and pike-perch.
The increasing flying Asian carp population are an invasive species that made it into North America and is creating a major ecological mess.
The only solution is to eat them all.
Quinton Phelps, a river ecologist explains that Asian Carp were originally imported from Asia to aquaculture facilities in Arkansas to control water quality and escaped and spread throughout the Mississippi River basin.
Carps can now be found in 23 of the United States open waters
Phelps explains that Carp pose many problems such as habitat alterations. They out-compete native species for food, cause overcrowding and are a negative impact on floodplains.
You can help prevent these invasive species from causing continued issues by catching and eating them.
