This is how it’s really done on fish farms. It’s difficult because it’s usually used for group spawning when you have fish all of the same variety. Spawning happens very naturally for pond fish, especially those kept outside year round. They winter naturally and come into spawning season raring to go.

Another reason to have partial shading in a pond is to prevent too much algae. It is thought that too much algae in a pond prevents goldfish from spawning. On the other hand, make sure to have some crystalwort in the pond around this time so that the fish have some around to place their eggs on. Make sure that this is the only place. No matter how much you’ve made the shallow end a hot bed of spawning, there’s always a pair of fish that will use the water hyacinth at the deepest part of the pond.

If you plan to raise the fry in the pond, remember to extract the adult fish – otherwise the fry will be eaten. Also, if you are raising the fry in the pond, you should be on the lookout for hydra. If there is hydra, remove as many of the fry as you can as soon as possible.
