Why are there so few salmon left? Why are there so few salmon left?
There are many reasons for the decline in salmon populations. Logging an area around a stream reduces the shade and nutrients available to the stream and increases the amount of silt or dirt in the water, which can choke out developing eggs. Dams cause fish to die from the shock of going through the turbines and from predators that eat the disoriented fish as they emerge from the dam. Overfishing...
Why do salmon change color and die after they spawn? Why do salmon change color and die after they spawn?
Salmon change color to attract a spawning mate. Pacific salmon use all their energy for returning to their home stream, for making eggs, and digging the nest. Most of them stop eating when they return to freshwater and have no energy left for a return trip to the ocean after spawning. After they die, other animals eat them (but people don't) or they decompose, adding nutrients to the stream...
Why do salmon eggs come in different colors? Why do salmon eggs come in different colors?
Salmon eggs (roe) range in color from pale yellowish-orange to dark reddish-orange. The color varies both by species and within species and is determined by water temperature, sediment composition, age, and other factors. The eggs vary in size from the tiny sockeye roe (average ¼ inch or 5.6 mm) to the large chum roe (average almost ½ inch or 8.3 mm). Also, if a salmon egg does not get fertilized...
Where can I find fish consumption advisories for my state? Where can I find fish consumption advisories for my state?
Most states have set fish (and wildlife) consumption advisories and recommended consumption levels. The state agency responsible for these limits varies. Examples of consumption advisory information can be found at the Environmental Protection Agency's Fish and Shellfish Advisories and Safe Eating Guidelines website.
