farmed salmon
cultured in
freshwater hatcheries
under controlled temperature and photoperiod on well-balanced diet reach the smolt stage (50–80 g) within one year (Figure 4). Smolts transferred to sea cages reach harvest size (~ 4 kg) in 10–15 months (Figure 5).

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 eggs do salmon lay at a time?

female salmon
can have between 1,500 and 10,000 eggs.
Why do salmon stop eating in freshwater?
Salmon change color to attract a spawning mate. Pacific salmon use all their energy for returning to their home stream, for making eggs, and digging the nest. Most of them stop eating when they return to freshwater and have no energy left for a return trip to the ocean after spawning.
How long do salmon live in the ocean?
5: Ocean Life Salmon may spend one to seven years in the ocean. Certain species have more flexible life history strategies, while others are more rigid. Chum may spend up to seven years at sea, but typically four. Pink salmon, on the other hand, spend a fixed 18 months at sea.
Do baby salmon eat their parents?
While new salmon are preparing to enter the world, their parents die (usually only days after spawning) Their bodies remain in the water or along the shore to decay and/or be eaten by other species. In this way they continue to nourish the environment around them.
Do salmon return to the ocean after spawning?
Most Atlantic salmon also die after spawning, but not all. About 5 to 10%, mostly female, return to the ocean where they can recover and spawn again.
Why does salmon turn red?
Salmon end up orange, pink or even red for the same exact reason: they consume carotenoids In the wild, salmon regularly consume a diet rich in a carotenoid called astaxanthin, an antioxidant that has the power to brighten their flesh. Farmed salmon, in contrast, get their carotenoids from manmade pellets.
How do salmon know where they were born?
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.
Can I farm my own salmon?

Do salmon eat their own eggs?
Salmon obviously have a taste for their own eggs (or the eggs of other salmon, at least), but in some cases, they actually digest and derive energetic benefits from egg predation. One coho jack was found to have 159 eggs in its stomach, and 13 percent of all salmon examined had consumed at least one egg.
Can salmon survive in the salt water?
Fish that can tolerate a wide range of salinity at some phase in their life-cycle are called euryhaline species. These fish, which include salmon, eels, red drum, striped bass and flounder, can live or survive in wide ranges of salinity , varying from fresh to brackish to marine waters.

Why do salmon have so many eggs?
Rather, the rate of predation on fish eggs is high because they produce such a lot of eggs Many fish produce thousands of minute eggs, each with an infinitesimally small chance of survival because this reproductive strategy in these species results in the highest number surviving to adulthood.
