probably to keep them safe from enimies trying to steal their eggs.
Female frogs produce hundreds of egg cells at a time because their eggs are externally fertilized and need to be released in water for the males to fertilize. Female humans produce only one egg cell at a time because the egg needs to be internally fertilized inside the female reproductive tract before implanting in the uterus to develop into a baby.
Salmon stay underwater all the time because salmon is a kind of fish which has gills for breathing while dolphin is a mammal.

Salmon farming got started because there was not enough fish for everyone. Everyone can get salmon even if it is not the salmon season if you farm salmon. The population is growing so we have to find more food. By farming salmon, there will be more seafood supply and half of the world's seafood is farmed. There is fresh salmon in every season, and fresh salmon is healthy. Commercial fishing can only harvest salmon at the right time of the year.
No because it needs time to develop
Salmon spend most of their lives in saltwater and only return to freshwater to spawn. Different species of salmon spend different lengths of time in the ocean due to differences in the amount of time it takes the salmon to sexually mature. Most salmon spend between 1 and 5 years in the Ocean before returning to freshwater to spawn and die.

A salmon returning from the sea to the river for the first time is called a "smolt." This term specifically refers to juvenile salmon that have undergone physiological changes to adapt from freshwater to saltwater environments. However, when salmon return to spawn after maturing in the ocean, they are typically referred to as "spawners."
