How Many Eggs Do Fish Lay?

The number of eggs a fish lays varies depending on its species, size, maturity, and environmental conditions. For example, a single female Atlantic salmon can lay up to 15,000 eggs, while a Pacific salmon can lay up to 4,000 eggs. The eggs are typically deposited in a nest or redd that the female has constructed in the gravel of a stream or river. The male salmon fertilizes the eggs, and they then incubate until they hatch into alevins (larval salmon).
