Building Cages for Fish Farming

If you plant to grow fish primarily for food instead of sport, consider cages. Cages allow complete and relatively easy harvest of fish from ponds and lakes, harvest that would be difficult or impossible by normal means. However, they must be built correctly if poor growth, death, and fish escape are to be avoided. The cage described in this Extra is appropriate for raising rainbow trout under South Dakota springtime conditions. Recommended stocking rates, times, and feeding methods are contained in other Extras
