A seasonal nursery pond allows for a resting period between each or every few batches of juvenile fish, improving pond conditions and reducing energy costs. Yearround designs cost more in power usage, through growlights, heaters, generators, etc.This refreshing period also serves to eliminate any growths of unwanted algae, weeds, or pests that may have formed in the previous growing stage.
If a nursery pond is allowed to fully dry out and be exposed to sunlight, even further purification can occur. Sulfides and toxins from decaying organic matter are processed underneath exposure to open air and sunlight, removing buildup of chemicals within sludge and leftover water alike.
