Fish

Certain populations of sockeye salmon, coho salmon, chinook salmon, and Atlantic salmon are listed as endangered. Sockeye salmon from the Snake River system are probably the most endangered salmon.
Most states have set fish (and wildlife) consumption advisories and recommended consumption levels. The state agency responsible for these limits varies.
Research suggests that even though amphibians are severely declining worldwide, there is no smoking gun – and thus no simple solution – to halting or reversing these declines.
There are about 230 species of amphibians, including about 190 species of salamanders and 90 species of frogs and toads, that can be found in the continental United States.  
Most Pacific salmon can be seen migrating from spring though fall, depending on the species.
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.
