The present invention provides for an aquatic environment an aerator having a temperature adjusted air inlet for aerating a quantity of water in a container, where the temperature of air pumped through an aerator may be cooled or heated, the temperature adjusted air entrained with water, and exhausted through an outlet into a bait well or a larger container, such as a pond for raising aquatic livestock. The temperature adjusted air may be supplied from an air conditioning unit in an automobile, a portable or fixed refrigeration unit, or gas flowing through an chilled environment of cooled liquid. In another embodiment, the temperature adjusted air may be drawn through an underground or underwater thermal stabilized conduit, using the natural temperature stability of underlying formations or layers. In another embodiment, where warm air is preferred, alternative sources of temperature adjusted air may be used, as for instance, an automobile heater, heaters using combustible fuels or electrical resistance heating, and even the underground or underwater thermal stabilization conduit that is also used for cooling during summer months. In some embodiments, the aerator may float, may be positioned at some relatively fixed point in the container, such as on the bottom, or may be a variable buoyancy aerator that varies the level at which the aerator is situated in the container. In another embodiment, multiple aerators are controlled in a larger container for aerating and mixing the container, where the aerators draw temperature adjusted air from a manifold.
