What is the reproduction of salmon?
Sharks and rays have internal fertilization and lay fertilized eggs. Most fish, including trout and salmon, lay unfertilized eggs. The eggs are fertilized externally by the male. Fish typically release hundred or even millions of eggs, which increases the chance that a few offspring will survive into adulthood.

How long does it take salmon to reproduce?
Sockeye typically spend two years at sea, coho spend about 18 months, and chinook can spend up to 8 years before journeying back to their natal streams to spawn.
Do Atlantic salmon lay eggs?
Once they arrive, females dig nests in light gravel and lay their eggs on the river bottom. Males fertilize the eggs externally, and then the females bury the nests. Unlike the pacific salmons (such as the chinook salmon), Atlantic salmon do not die after reproducing just once.
Where do salmon go to reproduce?
Most salmon species migrate during the autumn (September through November). Most salmon spend their juvenile life in rivers or lakes, and then migrate out to sea where they live adult lives and gain most of their body mass. When they have matured, they return to the rivers to reproduce.
How salmon find their birthplace?
Scientists believe that salmon navigate by using the earth’s magnetic field like a compass. When they find the river they came from, they start using smell to find their way back to their home stream. They build their ‘smell memory-bank’ when they start migrating to the ocean as young fish.
Do Atlantic salmon spawn in the spring?
Smolts migrate down streams or rivers to the ocean in the spring. After one or more years at sea, the adult salmon return to spawn. Even though spawning does not take place until fall, and only a few weeks may be needed to reach spawning grounds, some salmon will migrate up streams and rivers months in advance.

Each year mature salmon make the long journey back to their natal river to reproduce, just once. For the five species of Pacific salmon (Chinook, chum, coho, pink, and sockeye), this arduous journey is a race against the clock that ends in a fleeting romance and ultimately death.
How many times do Atlantic salmon spawn?
Unlike the various Pacific salmon species which die after spawning (semelparous), the Atlantic salmon is iteroparous, which means the fish may recondition themselves and return to the sea to repeat the migration and spawning pattern several times, although most spawn only once or twice.
How big do Salmons grow?
There is one species of Atlantic salmon. Chinook/King salmon are the largest salmon and get up to 58 inches (1.5 meters) long and 126 pounds (57.2 kg). Pink salmon are the smallest at up to 30 inches (0.8 meters) long and 12 pounds (5.4 kg), although they average 3 to 5 pounds (1.3-2.3 kg).
Why do salmon return to their birthplace?
Salmon come back to the stream where they were ‘born’ because they ‘know’ it is a good place to spawn; they won’t waste time looking for a stream with good habitat and other salmon. Scientists believe that salmon navigate by using the earth’s magnetic field like a compass.
How long does salmon usually live?
Most salmon species live 2 to 7 years (4 to 5 average). Steelhead trout can live up to about 11 years.Learn more: Questions and Answers about Salmon How many species of salmon are there and how large can they get?
Is farm raised salmon the same as wild salmon?
There’s a big difference between wild salmon and farmed-raised salmon. I know we look at them as being the same thing, but they’re not. Like most things, it all comes down to lifestyle. Farm-raised salmon lead a sedentary life; they’re in a small cage or a small tank. They are fed a lot so they grow quickly.

Cooking: Raw salmon may be cooked in a furnace,smoker,or over an open fire to produce cooked salmon.
How does salmon reproduce?
How Do Salmon Mate and Reproduce? Female salmon lay eggs in riverbed depressions that they create using their tails; the male comes along behind her and fertilizes the eggs. After fertilization, the female covers the depression. Females may make up to seven depressions, and they wait for males to fertilize each before moving on to the next
