An aquaculture process for dissolving gas in liquid by impinging two or more streams substantially and directly one to the other wherein the two streams enter an impingement zone from conveying means of substantially equal shape with a velocity greater than 2 ft/sec, wherein at least one of the streams is a gas/liquid mixture and at least one of the streams passes through a venturi prior to impingement, the impingement of the two streams taking place above a water line of an environment being discharged into so as to offset the pressure of the fluid discharging from the process, the impingement of the two streams further taking place in a contained environment such that the fluid dynamics of each stream just prior to and after the point of impingement is substantially turbulent, whereby after impingement, the streams are discharged at velocities that have substantially turbulent fluid dynamics with the discharge from the impingement zone not changing direction before discharge to the surrounding environment, the gas/liquid being partially recirculated back to the impingement zone with a recirculation ratio that is sufficiently large so as to maintain the gas concentration in the liquid substantially constant.
