How to Breed Pond Fish
Increasing your pond fish stock is relatively simple when you provide a few basic conditions. Many people enjoy keeping carp varieties for entertainment and fun. Koi pond fish make a valuable addition to any pond and spawning additional fish can save a lot of money for very little work. Learn how easy it is to breed pond fish and enjoy the rewards.
Purchase additional mature breeders in the spring if needed. The rule of thumb for most pond fish is about three females for every male. Koi should be a minimum of three years old while goldfish must be two years of age.
Plan to breed pond fish during the spring and early summer. This is the ideal time when pond waters have attained a suitable temperature of 74 degrees Fahrenheit. If needed purchase a heater to gradually increase water temperature. Proper temperatures induce pond fish to breed when additional conditions are met.
Separate the females and males. Place screens or netting in the pond to create a separation area. Separating males from females provides the option of selective breeding to produce superior stock.
Prepare an area for spawning. A spawning area can be a tub with adequate water supply and filtration, a separate tank, a sectioned off portion of the main pond or a secondary pond. The spawning area should contain several spawning mops in one location of the pond. These float on the surface and dangle into the water where the female will lay her eggs. If you are short on space this area can also suffice as a holding tank for newly hatched fry.
Put the female fish into the spawning area and allow her about a day to explore her new habitat and adjust. Fresh water, new habitat, separating the sexes and ideal water temperature trigger spawning behavior. Add a couple of males that you have chosen for breeding in with the female. Let nature take its course.
Remove the fish after the female has deposited her eggs into the string mops. Or you can remove the string mops with the attached eggs into another location with similar water temperatures. Any adults left in the same pond or tank will eat the new eggs.
- Turn off water filtration systems in the hatching pool or pond. Expect eggs to hatch within about two weeks. Baby fish will feed off algae to start and then you can introduce them to baby fry food.
