The phrase "migration and spawning" is correct and usable in written English.
You can use it when talking about the movements of certain animals, such as fish, birds, and butterflies. For example, "Each spring, salmon make an incredible journey of migration and spawning in their native rivers and streams."
The report said warming sea temperatures were related to changes seen in the depth, distribution, migration and spawning behaviours of fish.
Last spring, Britain's Marine Climate Change Impacts Partnership, which unites a wide array of scientists, government agencies and industries, issued an analysis that found "clear changes in the depth, distribution, migration and spawning behaviors of fish -- many of which can be related to warming sea temperatures".
For example, selection on spawning date depends on at least three changes that are uncertain: (i) the advance in optimal emergence timing, (ii) a plastic change in spawning date owing to warmer waters, and (iii) potential costs of longer delays between migration and spawning.
Altering natural flow systems can lower water tables, increase saltwater intrusion to coastal areas, and harm fish migration and spawning, it said.
Using passive integrated transponder (PIT) telemetry, this study evaluated the efficacy of two such conventional, technical fishways (pool and weir and plain Denil baffle) located on the Yorkshire River Derwent, north-east England, for the threatened anadromous European river lamprey Lampetra fluviatilis, an anguilliform swimmer, over the upstream migration and spawning seasons.
Over the past decade, however, environmentalists have targeted dams as outmoded, inefficient energy providers with serious impacts on water flow, surrounding and downstream environment, species migration and spawning, sediment collection, algae blooms, and other damage to the natural process.
The specific aim of this study was to determine whether segregation based on differences in migration and spawn timing prevented hybridization of hatchery fish and wild fish and minimized ecological impacts by preventing natural propagation of hatchery fish.
To represent a stock that undergoes an annual migration between feeding and spawning grounds, we draw model parameters from Atlantic cod (Gadus morhua) in the northern part of its range.
The early migration and spawn timing of hatchery fish were believed to effectively prevent them from interbreeding with wild fish.
Thus, migration and spawn timing of hybrids would be expected to overlap with the timing of both populations.
Ample evidence shows that much of the variation in migration and spawn timing in salmonid fishes is attributed to additive genetic variation (Carlson and Seamons 2008).
