Understanding the Lifecycle of Salmon - American Oceans

Salmon Life Cycle - State of Salmon
Click through each section below to learn about the different phases of the salmon life cycle. Salmon begin their lives as tiny eggs in freshwater streams and rivers. Fertilized eggs lay in redds, or gravel beds dug out along the streambed, where the flow of water provides oxygen and removes excess sediment or waste products.
Salmon spend 1-8 years at sea growing and maturing, depending on the species. Chinook mature between 3-8 years old; Sockeye between 4-5 years; Chum between 3-5 years; Coho around 4 years; Pink around 2 years. Adults grown much faster in the ocean than in freshwater due to the increased abundance of food.
Salmon Life Cycle and Seasonal Fishery Planning - NOAA Fisheries
Learning about the life cycles of salmon and steelhead, the different ages of when they return, times of year and migration patterns, can help fishery managers target specific stocks and forecast the abundance of fish available in each fishery. Different salmon and steelhead life histories require different methods to estimate their abundance.
The Salmon Lifecycle: An Epic Migration - Earth How
Fascinatingly, a salmon’s life can span anywhere from 2 to 7 years, depending on the species. This journey is essential for their reproduction and survival. Let’s explore the stages of a salmon lifecycle in more detail.
Species & Lifecycle - Pacific Salmon Foundation
The Pacific salmon life cycle depends on the species. Some spend hardly any time in natal streams; some spend years. Some mature at two years of age; some mature at five. Some live for only a couple of years; others live for ten. And some, like Steelhead and Cutthroat, can spawn more than once.
The Salmon Lifecycle - The Atlantic Salmon Trust
Atlantic salmon are anadromous, migratory fish which means they spend part of their life in the ocean but they breed and lay their eggs in freshwater. At each stage of the life cycle of the salmon distinct changes take place.
stages of the Pacific Salmon The salmon life cycles has 6 stages: Egg (Stage 1), Alevin (Stage 2), Fry (Stage 3), Smolt (Stage 4), Ocean Adult (Stage 5), Spawning Adult (Stage 6) 5. Pass out two “Life Cycle Diagrams” to each group. Encourage students to work in pairs to complete the diagram using the pieces (life cycle stages) provided. (10 ...
