YOKIHI MEDAKA
Yokihi Medaka was created around 2004 by Mr. Yukio Oba in Hiroshima Prefecture around 2004.
It was selected and bred from the vermillion-red medaka that rarely appears among the amber medaka.
Yokihi Medaka is a representative breed of improved medaka that sparked the current popularity of medaka in Japan.
Medaka Farm Breed
These eggs are 3nd generation YOKIHI medaka came out light orange on top born at MEDAKA FARM California, carefully hand collected one by one after fertilized .
Hatch
The conditions for hatching are 250°C (482? )/ day.
The water temperature is greatly related to the number of days until the eggs hatch.
If the water temperature is high, it will hatch faster, and if it is low, it will take longer to hatch.
There is a method called integrated temperature that calculates the approximate number of days an egg will hatch.
The cumulative temperature of medaka is 482? (250 °C) days .
Number of days (days) = 250°C days /(÷) water temperature °C ?
?water temperature °C x number of days (days) =250°C days
The calculation formula does not hold in ?, it is calculated only in degrees Celsius.
For example, when the water temperature is 25 °C (77°F), it hatches in about 10 days and the water temperature is 20°C (68 °F) , it will take 12 to 13 days.
30°C (86 °F) = 8 - 9 days
25°C (77°F) = 10 - 11 days
20°C (68 °F) =12 - 13 days
15°C (59 °F) =16 - 17 days
