Salmon turn red when they spawn. It is hypothesized that the color helps camouflage them from predators and prey, and it may also be a mechanism for attracting mates. The reason why salmon are so brightly colored in some places but not others remains unknown.,
The “Salmon change shape when they spawn” is a question that has been asked for years. It’s not entirely known why salmon turn red when spawning but scientists believe it’s because the male fish release a chemical into the water that makes the female more receptive to mating.
Salmon begin to absorb their scales as they reach their breeding sites. Their meat contains carotenoid colours, which are transported to their skin and eggs. They are more obvious because of their crimson skin, which may indicate that they are ready to spawn. The pigments may also aid in the fish’s oxygen absorption from the water.

Also, what causes salmon to die once they have spawned? To attract a spawning partner, salmon change color. When they return to freshwater, the majority of them stop feeding and have little energy left to return to the ocean after spawning.

Can you consume salmon that has turned red in the same way?
Salmon are unable to reproduce after they have died. When a salmon spawns, it lays eggs to hatch, which are known as roe, or salmon roe. The majority of wild salmon is captured and killed after spawning, and hence consumed.
When salmon spawn, why do they alter shape?
Some species’ males may grow a hooked snout, humped back, and lengthened teeth to lure a partner and protect spawning area. After spawning, all adult salmon die, and their corpses decompose, supplying nutrients to future generations of salmon.
