Interpretive Summary:

Technical Abstract: Most transporters of live fish provide supplemental aeration by diffusing pure oxygen in hauling tanks. Transporters typically use a thumb rule approach, in which knowledge of a particular species, ambient air temperature, haul tank water temperature, loading density, and transport time are considered when determining oxygen flow rates. Components of the thumb rule were combined with results of scientific studies of channel catfish Ictalurus punctatus and blue catfish Ictalurus furcatus metabolism to produce a mathematical model for estimating the volume of oxygen required by a given biomass of each of the listed species over a given transport time. The model estimates the volume of liquid oxygen needed to supply respiration needs during transport, and includes an informal expense analysis for each haul. The model was programmed in Microsoft Excel to make it readily accessible to interested parties.
