It is a difficult journey from egg to spawning adult. Only about two percent of all salmon hatched will live to adulthood.
Consequently, what percentage of fish eggs survive?
High egg survival has been reported in three freshwater species which spawn in vegetation: 60-95 percent for northern pike (Franklin and Smith, 1963), 80-94 percent at high oxygen concentrations for carp (Nikolskii, 1969), and 34-90 percent for carp-bream (Nikolskii, 1969).
do all salmon die after they spawn? The salmon run is the time when salmon, which have migrated from the ocean, swim to the upper reaches of rivers where they spawn on gravel beds. After spawning, all Pacific salmon and most Atlantic salmon die, and the salmon life cycle starts over again. When they have matured, they return to the rivers to spawn.
Regarding this, how many eggs do salmon lay?
What do salmon eggs need to survive?
Salmon eggs need cold water to live. If the water is too cold or too hot, the eggs will die. A salmon begins to grow inside the egg. The yolk gives it food.
