The application provides a water lens heater for warming and heat preservation of a mariculture pond and a use method, and relates to the technical field of seawater heating. The heater comprises a water lens unit and at least one heat preservation unit, the water lens unit and the heat preservation unit form a stacked structure distributed in an up-down mode, the water lens unit is located below the heater, and the heat preservation unit is stacked above the water lens unit; a water injection cavity for water injection is formed in the water lens unit, and an air cavity for air injection is formed in the heat preservation unit; the water lens unit and the heat preservation unit are both made of a light-transmitting film. The heater can effectively shorten the warming period of the mariculture pond through the synergistic effect of the three mechanisms of heat locking through the greenhouse effect, light concentration and efficiency increase through the lens, and multi-layer air heat insulation, can raise low-temperature seawater to a suitable temperature for breeding in several hours or 1-2 days, and greatly improves fattening efficiency and production rhythm.
