Trout can thrive in even the simplest garden pond, assuming it is stocked with an appropriate number for the size. Raising trout is not only an entertaining hobby, it can become a tidy side income with a bit of business savvy.
The University of Tennessee recommends no more than 2,500 trout per surface acre. If you're using cages to simplify harvest, the University of West Virginia Extension Service recommends no more than 2,000 per acre.
Since trout are cool water fish, the pond temperature should consistently be between 12.8 and 18.3 degrees Celsius. Some species of trout, such a rainbow trout, can survive slightly lower temperatures.
Trout can be harvested by traditional fishing methods, nets or in bulk by raising them in cages. Cage raising is the only method that requires daily feedings.
