A system for algal fostering and fishery initiating and maintaining and for reducing greenhouse gases comprising a plurality of pumps (100) having hoses (110) for drawing deep cold and nutrient rich water from the bottom of an ocean and pumping it to the ocean s surface and a plurality of heat exchangers (112) drawing the heat from the warmer waters surrounding the hoses the plurality of heat exchangers being in heat communication with at least a portion of the hoses for gradually warming the ascending deep cold and nutrient rich water during its ascent through the hoses so that it is substantially at ocean s surface water temperature at the time it arrives at ocean s surface.
