Koi Breeding Part 1!
Yesterday, I was feeding my koi’s in their ponds where they usually hold their swimming exhibition and noticed that two of my beautiful female kuhako koi’s moved unusual and some of my male koi’s chased after them. I immediately got my fishnet and checked if they were sick and needed their medicine. When I gently rubbed their belly I noticed that some fluids came out and their genital (papilla) opening were big and swollen. From there I already knew that my koi’s were already ripe and ready to produce egg.
1. Sexing – First you need to determine the female and male koi. Females are more rounded than male. Male fish pectoral fins tend to be larger and more pointed than those females but this is by no means always the case. During the breeding season, male fish can display a rough surface to the gill plates, again however, not always. One way of determining is to net the chosen fish and gently rub the lower abdomen wall with your thumb towards the vent. Male koi will show signs milt from the vent and females will release eggs.
2. Parent Pairing – you can choose any variety you want for as long as the materials are all adult to have a successful spawning. Always remember that male genes tend to be dominant in any pairing. You can also watch video or ask some of koi breeders regarding what kind of koi variety that produce quality koi. Here is a video that shows best pair for koi breeding .Watch this..
3. Koi Spawning – In spawning the male and female koi they should be placed in the ideal pond that has 2x3x1 meter deep and use a spawning net in your main pond, use removable nests so that you can easily transfer and grow-out in a wider pond and remain others with the parent fish. You can also use tank in spawning. Some breeders inject the parent fish with hormones to induce ovulation and then placed into fiber tanks line with nest.
