  • Re-circulatory System
  • Movement-through System
  • Stagnant-pond System

Water is handled by totally different strategies and equipments to guarantee wholesome aquatic setting for catfish manufacturing. Additionally, the system controls pH and water temperature to guarantee a conducive setting for fish progress.

Typically, re-circulatory system is made up of fish upkeep tank and composite system. An entire re-circulatory system might comprise the following; Tank, display screen/sand filter, filters, aerators/oxygen pumping machine, submerged heater/chillers/warmth exchanger, linking pipes.

Deserves of Re-circulatory System

  • It promotes effectivity of water administration by guaranteeing restricted water useful resource is judiciously used.

De-merit of Re-circulatory System

  • Costly to arrange.
  • Excessive value of upkeep.
  • Can solely be dealt with by educated manpower.

This may allow water to circulation from the supply into the pond with none assist of electrical energy.

Benefit of Movement-through System

  • Easy to arrange.
  • Low setup value.
  • Straightforward to keep.
  • Low value of upkeep.
  • Might not want electrical energy to function.

Ponds underneath this technique are under-stocked or reasonably stocked to guarantee fishes are raised for the complete season with out a lot water administration challenges.

At the time of harvest, pond water could also be utterly drained by the use of pumping machine or lease pipe. The place farmer is just not certain of the recharging energy of the floor water, pond is poisoned to retain the water for an additional season manufacturing.

Benefit of Pond System of Water Administration

  • Cheaper to keep.
  • Much less probably to be affected by exterior illness/ an infection.
  • Straightforward to handle and keep.
  • Much less probably to be affected by flood.
  • Can be utilized in absence of floor water.

Demerit of Pond System of Water Administration

  • Can’t be used for top density manufacturing.
  • The entire inventory could be misplaced in case of illness outbreak.
  • When reasonably/overstocked, fishes might not attain their progress potential.
