Seasonal nursery ponds allow for time for the pond to rest between each stage of new fry, preventing unwanted algae and fish from getting a foothold, and helping remove unwanted toxins. Allowing the pond to fully dry out and be exposed to sunlight can be a powerful way to further disinfect and refresh your nursery pond. Sunlight can oxidize stubborn compounds like sulfides, and helps breakdown any leftover waste or organic matter.
Yearround nursery ponds require temperature control during extremely cold or warm seasons, which can cost lots in energy or labor costs.
