This article details several tips on how to properly care for your Koi fry. Highlighting commonly asked questions such as the best water temperature, how to feed them and pointers on keeping your pond in ideal breeding conditions.
If you just noticed that your pond now has a million little koi fry swimming around then skip down to the feeding section but if you haven’t bred koi yet and need an introduction then read on. Spawning typically occurs in the early summer months and is very water temperature dependent – 68 degrees F is the minimum for spawning . Your adult koi will have to be sexually mature to engage in successful mating and this typically occurs at age 2 for males and at age 3 for females. Keep in mind when you are selecting the parents that the larger the female, the more eggs she can produce. Usually spawning activity, and the behaviors associated with it, will take place in the early morning and may only last 30 minutes. The whole process is a bit rough as the male needs to physically stimulate the eggs to be released by nudging the female’s belly. After eggs are released, the male fertilizes them by releasing sperm.
