  6. 6. Carrying Capacity ofCages 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
  7. 7. 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
  8. 8. Maintenance ofCages 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
