This strain belongs to the Southern Japanese Population, and derived from the wild population in Chiba. This fish is too shy of people. The eggs are characterized by unusual pattern of oil globule fusion after fertilization.
Notes
This strain is maintaining as a closed colony (descendants from multiple parents) after 108 generations with brother-sister mating.
