Trout Farming: A Guide to Production and Inventory Management

Jeffrey M. Hinshaw

Opening Paragraph:
The carrying capacity of a trout rearing unit is dependent upon fish size, and on several water quality factors, principally oxygen content, temperature, water flow and volume. Rearing units most common to commercial trout farms in the South are a series of rectangular concrete tanks, sometimes called raceways. Carrying capacity is usually expressed in terms of pounds of fish per cubic foot of rearing space or water flow. A number of different formulas have been devised to calculate carrying capacities, taking into account oxygen consumption, rate of increase in fish length, water volume and temperature, feeding rates and other factors. As long as the appropriate limiting factors are monitored by the operator, the choice of a particular estimator is a matter of operator preference.
