good topic actually, viability and fertilisation.
anyone had experience with really great fertilisation rates and can come up with some reasons (most likely) for why there was such a good rate?
apart from health of parents and prime condition, ive heard somewhere or read it atleast that you can get certain koi crosses that just dont produce viable eggs or 25% or something are just never gonna develop through a fatal gene combination or something they called it.
with koi i ussually just use an overkill of breeders and let nature take its toll but id like to look into doing it another way so i can stock known quantities into ponds.
anyone hatch in mcdonald jars? flow through hatchers? anyone used salt or milk to make them non sticky and flowing around a jar?
the big one id like to know, once the egg hasnt fertilised and it becomes prone to fungus, does that fungus then attack good eggs?.
i worked with someone that reckoned that fungus attacked eggs and still some of them hatched. i thought i could see some embryos inside a fungus egg once as well which would back the theory.
this would indicate that fungus doesent only attack non viable happening eggs but can attack whatever. i know i get fungus in cold water more so and warm hatches seem better. maybe its fertilisation is lesser in cool water that allows the fungus to attack.
how about you guys that use UV that should tell us something, do you get brilliant fertilisation and hatch rates or what?
