The provided diagram depicts the life cycle of a salmon fish dividing it into different stages, from its egg stage till becoming adults. Overall, a salmon fish goes through six main phases to fully grow from their hatching period and they spend their lives in three distinct locations – river, estuary and ocean.
Adult salmon fishes lay eggs in rivers and incubate their eggs there. Thus the life cycle of a salmon fish starts from the incubation stage in a river. After emerging from eggs, the infant salmon spend their next stage in freshwater and this phase is called emergence. Then they are reared in freshwater to grow further. After few days, these fishes swim to river estuaries where their rearing continues. At this stage, their size becomes a bit larger. Afterward, the maturing fishes migrate to the ocean and become adults. Finally, grownup salmons move to spawning areas of rivers to lay eggs and the life cycle of the next generation starts over.
