Trout and salmon are both cold-water species. Meaning these fish need cold water condition just to survive. The water must be between 50 and 65 degrees Fahrenheit to thrive. These fish in many areas are already struggling to be comfortable in these waters in certain seasons throughout the year, but the worst is yet to come.
According to Natural Resources Defense Council, they explain how by 2090 as much as 18 to 38 percent of all trout and salmon will disappear and die off. The reasoning for this is because of the steady increase of water temperature as we move forward living with Global Warming. These cold water habitats are projected to rise 0.7 to 1.4 degrees Fahrenheit by 2030 and 2.2 to 4.9 degrees Fahrenheit by 2090. The projections are all depending on future emissions of heat-trapping gases and the climate model. These effects will be expected to vary by region. For trout, the largest numbers in losses will occur in the South, Southwest, and Northeast because of the drastic climate changes these areas endure.
These fish species dying off will affect the workforce as well. The combined fisheries range from $1.5 to $14 billion a year. Not only affecting us humans, but it also affects the ecosystem because these fish are a vital food source for many animals such as various species of birds and bear.
