marine fish lay eggs in fresh water river
Fresh eggs float in salt water because the density of salt water is more than the density of the egg. But fresh eggs do not float in fresh water because the density of water is less than that of the egg. Salt increases the density of water.

Eggs float in salt water but not in tap water, which is a fresh water. This is because salt water is more dense than fresh water.
