Short answer salmon spawning:
Salmon spawning is the process by which adult salmon swim from feeding grounds in the ocean to freshwater streams or rivers where they lay and fertilize eggs. After laying their eggs, most die off while some species return back to sea for future spawns.

When do salmon spawn?
Salmon are fascinating creatures. They spend their lives in the ocean and then swim back upriver to lay their eggs, or spawn. But when exactly is this spawning season? Here’s what you need to know:
1. Salmon generally begin migrating upstream from the ocean between late summer and early autumn.
2. The exact timing of each species’ migration varies depending on factors like water temperature, river currents, and food availability.
3. Once they reach fresh waters where they were born as babies (or fry), female salmon will dig a nest called a “redd” using her tail muscles about 8-18 inches deep into rocky gravel substrate at depths of 6–24″ below surface level while males fight for access until mature females have lined them with sufficient downwelling streamflow oxygen levels stabilizing sediments combined with interstitial space relative void ratio structures by which those embryos can develop
During this time it’s important that these redds remain undisturbed—stepping on or digging around one could crush fragile eggs!
4.Not all salmon die after spawning; some return downstream and repeat this cycle multiple times before dying naturally..
In summary: While there isn’t an exact calendar date for when every single cohort per run starts moving from salt to freshwater habitats Most typically Conception & Imprinting occurs within two weeks post-hatch,parr smolts sexual maturation rate happens usually taking till age five-eight biology studies suggest predictable migrations patterns based upon hydrological phases providing clues National parks often include areas highlighted educational programsvisitor centers best witness such natural spectacles firsthand!
– How far upriver will salmon travel to spawn?
Salmon often travel far upriver to spawn, but just how far can they go? The answer depends on several factors such as the species of salmon and the distance between their spawning site and the ocean. Here are some quick facts about salmon migration:
1) Different species of salmon have varying range limits for migrating upstream. For example, Pink Salmon usually travel only a few miles from sea while Chinook or King Salmon may swim over 1000 miles away.
2) Environmental obstacles like dams may hinder normal hatchery migrations by reducing water flow through channels which forces fish into deep rivers closer towards branch streams nearer coastal areas where turbidity is less pronounced
3)Large parts of North America boast viable Pacific drainage systems filled with wild runs that migrate multiple hundreds – thousands – feet during spawing season;
4) Atlantic Salmons also makes it ways back home via similar routes taken in reverse direction (ocean system);
5) In general most adult Pacific almon will oviposit no more than fifty yards freshwaters shores;
Although precise numbers vary depending on these variables, many experts agree that some types of salmons demonstrate an impressive ability to navigate upstream regardless anys environmental barriers imposed upon them! So there we have I hope you got answers regarding – How Far Upriver Will Salmon Travel To Spawn?.
