Fishpond

It is a structure used to hold a standing body of water with limited flow.

 

Types of fishponds

  • Embankment pond (levee ponds): is made by construction of walls above the ground level to impound water without excavation into the ground.
  • Excavated pond: made by digging out the soil and then using the dug soil to build pond embankment.
  • Partially excavated pond with low walls (ravine ponds):

Features of a good fishpond

  • Permanent /reliable water source throughout the year
  • Pond walls or dykes to hold the water in the pond.
  • Water controls to manage water level and flow.
  • Tracks and roadways along the pond wall for easy access.
  • Harvesting facilities and other equipment for water and fish management.
  • Security
  • Access to market

Care for fishpond

  • Feed the fish regularly and remove excess food and debris from the pond
  • Observe the fish for healthy swimming, eating, and breathing behavior
  • Monitor the water level, temperature, pH and quality, and add new water if needed
  • Clean the pond and the pump, filter, lines, and fountains regularly
  • Manage the nearby plants and grow water plants to provide shade and oxygen
  • Control water weeds

To prevent diseases in your fishpond

  1. Water Quality Maintenance:
  • Regularly test the water quality for pH, ammonia, nitrite, and nitrate levels.
  • Maintain proper water circulation and aeration to prevent stagnation.
  • Use a good-quality filter to remove debris and excess nutrients.
  1. Quarantine New Fish:
  • Before introducing new fish, quarantine them in a separate tank for a few weeks.
  • Observe their health and behavior during this period to prevent the spread of diseases.
