A vehicle mounted ram-air powered aerator for live fish containers is disclosed comprised of a generally funnel-shaped air collector having an angular discontinuity between its forward and rearward sections which increases internal turbulence and improves air collection efficiency; an air collection port displaced forward from the back wall of the collector, thereby defining a rainwater sump having holes to drain away the water to prevent flooding of the fish container and also, incidentally, to improve the air flow pattern such that collection efficiency is improved. The collector is integrally molded with a stand-off/support arm and vehicle window mounting clip so designed as to position the collector above and outboard of the low-pressure region of the vehicle slip stream and to thus further improve air collection efficiency. The air collector port is protected from blockage due to large insects and airborne debris by means of an easily removable screen positioned at the mouth of the collector and having rectangular apertures with tapered sidewalls to maximize air flow. The collected air is delivered to the fish container by means of a flexible air tube.
