Fish extract oxygen from water using gills, but gills cannot extract oxygen from air.
A few species of fish (e.g. lungfish, snakehead) have some ability to extract oxygen from air (e.g. lungfish use a modified swim bladder like a lung) and can survive short trips across dry land from one shallow pool to another.
