What do unfertilized koi eggs look like?
It is inevitable that not all koi eggs will be fertilized, even under perfect conditions. Just 24 – 48 hours after spawning, unfertilized eggs can easily be distinguished from fertilized ones as they eventually turn milky white in color and look fuzzy (due to fungal growth).
What time of year do koi lay eggs?
The chasing and splashing were a result of the koi spawning. Spawning season usually takes place in the early mornings during May and June. As the koi prepare to spawn, the males will start following and showing interest to the most receptive and fertile female.
How many days does it take for koi eggs to hatch?
In about two to five days, the eggs will begin to hatch, and baby koi, known as “fry” will emerge. After her part is complete, the female koi will begin creating new eggs. These will be laid in about a year’s time, as that’s how long it takes for them develop.

How can you tell if koi is carrying eggs?

How Many Koi Eggs Survive? A female Koi can lay up to 100,000 eggs, although achieving this number is unusual. You can expect approximately 50,000 eggs from a healthy one-pound female, but only around half of these will survive hatching and fewer still will survive the fry stage of life.
What do koi eggs look like before they hatch?
If you come across some newly-hatched eggs nestled on the tip of a pond plant in your backyard, expect to find a population boom within the next few days! Typically, koi eggs will hatch in less than a week. Koi eggs are very small, bead-like specks that can vary from milky white to yellow or green.
