Description:
The title sockeye salmon refers to “Suk-kegh,” that means “red-fish” within the native Halkomelem language of Alaskan inhabitants.
Sockeye encompasses a fusiform, streamlined, laterally compressed physique enabling long-distance marine migration and upstream run.
Sea-going sockeye are darkish metal blue to greenish-blue on the highest (giving them their “blueback” title), iridescent silvery sides, and white stomach. Some people could exhibit darkish speckling and irregular marks on the dorsal fin.
As sockeye return to their freshwater spawning grounds, their heads flip olive inexperienced, and their our bodies flip vivid purple, therefore their title, “purple” salmon.
Male sockeye develops a humped again and hooked jaws full of tiny, seen enamel.
Common size 18 in. and weigh 5–15 lb. Lifespan is about 4-5 years.
Kokanee salmon
Some sockeyes don’t migrate to the ocean and reside their complete lives in freshwater lakes. These landlocked sockeyes are often known as the Kokanee within the native Salish language. They’re much smaller in dimension and measure about 10-12 In.
Biology
Sockeye salmon are anadromous fish. Within the spring, fry emerge from the nest, go to the ocean throughout their first summer time earlier than migrating to the ocean. They develop shortly in dimension and return as adults to natal streams to spawn in the summertime.
Simply earlier than spawning, the feminine selects an acceptable floor, often with gravel backside, and digs a nest with its tail.
The feminine is then attended by a dominant male and generally just a few subordinate males.
All grownup sockeye die after spawning.
Habitat
Sockeye is the smallest of Pacific salmons. In a approach just like different salmon species. They’re migratory fish finishing their fascinating journey from natal freshwater streams, rivers, lakes, and deep ocean waters and again once more to their natal waters to spawn and die.
Sockeye habitat requires chilly, clear, oxygenated water to outlive as heat ocean temperatures improve the vitality expenditure through the migration and produce fewer eggs on the spawning grounds.
Fry feed totally on zooplankton, fish larvae, bugs, whereas adults largely depend on marine zooplankton, krill, bugs, and small crustaceans.
