But the return rate today is less than one-fifth of what it was decades ago. Salmon fry predominantly feed upon zooplanktons until they reach fingerling sizes, when they start to consume more aquatic invertebrates such as insect larvaemicro crustaceans and worms. NOAA Fisheries conducts various research activities on the biology, behavior, and ecology of sockeye salmon.

Yet on the Wild salmon population, there are also signs of the coming northern hemisphere spring, signs Wilc which we can hold hope popultaion the year ahead: the thrusting shoots of daffodils, the dainty heads of snowdrop flowers emerging against all the frozen, wintery odds. Such moments in the cycle of nature always instil a sense of optimism and, of course, we need that more than ever this year. We fervently hope the 12 months ahead will see us emerge from this miserable pandemic. But it also needs to be the year in which nature itself is given a chance when natural systems that are breaking down are addressed and revived. Not least the rivers and streams themselves.
