Salmon undergo distinct life stages, feeding on smaller fish as juveniles and larger prey like squid as adults. They migrate from freshwater streams to saltwater to feed and grow before returning to spawn. Females lay a large number of eggs, between 3,000-15,000, because only some will survive to adulthood and ensure the continuity of the species. Their populations have declined due to human impacts like dams, logging and development.

1. Salmon Diet:The young will eat smaller fishes like the stoneflies while the adult salmon will eat larger food like the arctic squid. Life stages: The salmon undergoes their greatest feeding and growth in salt water, however adults return to spawn in native freshwater streams where the eggs hatch and juveniles grow through several distinct stages. Human impact: Salmon decline in Lake Ontario goes back to the 18th-19th centuries, due to logging, soil erosion, as well as dam and mill construction. By 1896 the species was declared extirpated from the lake. Reproduction: The female lay about 3000 to 15000 eggs at one time. Migration: Atlantic salmon migrates from its home stream to an area on the continental plate off West Greenland. During this time in the salmon's life, they face predation from humans, Greenland sharks, skate ,cod and etc. Some dolphins have been noticed playing with dead salmon.

2. Behavioral adaptation Fry and Parr have been said to be territorial, but evidence showing that they guard territories is inconclusive. While they may occasionally be aggressive towards each other, the social hierarchy is still unclear. Many have been found to school, especially when leaving the estuary. Adult Atlantic salmon are considered much more aggressive than other salmon and are more likely to attack other fish than others. Where they have become an invasive threat it has become a concern that they are attacking native salmon such as Chinook salmon.

3. Why there is a need for the female salmon to spawn about 3000 to 15000 eggs at a time? As within the few thousands eggs, only some can survive and so the female salmon has to spawn more eggs in order for the continuity of its species. The salmon eggs
