The female digs out a hole called a redd. The preferred depth for steelhead spawning is 6 to 14 inches (150 to 360 mm). [10] She then lays the eggs, and a male fertilizes them. The females will then cover the eggs with the gravel. Depending on the size of the female she may lay up to 9,000 eggs. The female then buries the eggs in a foot of gravel.
The rainbow trout (Oncorhynchus mykiss) is a species of trout native to cold-water tributaries of the Pacific Ocean in North America and Asia. The steelhead (sometimes called steelhead trout) is an anadromous (sea-run) form of the coastal rainbow trout (O. m. irideus) or Columbia River redband trout (O. m. gairdneri) that usually returns to freshwater to spawn after living two to three years ...
In pre-spawning Salmo and Salvelinus males, the lower jaw elongates and the hook develops; female salmon do not develop a kype. [3] Bull trout ( Salvelinus confluentus ) are adfluvial (adults spawn in streams but subadults and adults migrate to lakes for feeding) and sometimes develop a kype, however, although this may occur in some populations ...
I decided lack of rain was limiting the number of fish in the river, and made the decision to fish the rest of the day out in the bay.
Oncorhynchus is a genus of ray-finned fish in the subfamily Salmoninae of the family Salmonidae, native to coldwater tributaries of the North Pacific basin. The genus contains twelve extant species, namely six species of Pacific salmon and six species of Pacific trout, all of which are migratory (either anadromous or potamodromous) mid-level predatory fish that display natal homing and ...
Salmonidae (/ s æ l ˈ m ɒ n ɪ d iː /, lit. ' salmon-like ') is a family of ray-finned fish that constitutes the only currently extant family in the order Salmoniformes (/ s æ l ˈ m ɒ n ɪ f ɔːr m iː z /, lit. "salmon-shaped"), consisting of 11 extant genera and over 200 species collectively known as "salmonids" or "salmonoids".
The female kokanee creates a nest called a redd. She will lay around 1,000 eggs, depending on food availability. Eggs hatch within 110 days, and the juveniles swim out to the lake. [20] [9] During spawning, the males turn bright red and develop a humped back and an elongated jaw similar to the male sockeye salmon.
Females become extremely aggressive with each other over nesting sites, and with males until these are dug. Males then fight for the right to mate. Once a female has chosen a mate, usually the largest male, she lays her eggs onto the redd, while he simultaneously releases milt (sperm) onto the eggs. Unchosen males also sneak in to release milt ...
