Grow out fish in a body of water that is not practical to drain

Spawn bluegills and yellow perch

Carrying Capacity of Cages

Novice should keep densities low

Keep in mind carrying capacity of pond

Publications show up to 15 lbs. per cubic foot

Personally would never go above 3 lbs. per cubic foot

Page 7: 2 cage culture

Rules of Thumb

Must have cover on cage

Provide shade on up to half of cage to reduce stress

Feed high quality diet

Overwintering can be problematic

Large mature fish and fish not originally grown out in cages get stressed

Page 8: 2 cage culture

Maintenance of Cages

Keep Algae from clogging cages with push broom and extendable handle

Replace leaking or damages floats

Keep bottom of cages at least 2 feet off the bottom

No swimming around cages

Off season power wash

Harvesting Cages Deeper than width easier to harvest on shore

Can use pole and pulley to winch up cage for dipping

Do not lift cage completely out of water with fish in it!
