If the time period is shorter, females will still be incubating eggs. After more than 14 days, fry numbers will be reduced from cannibalism. Fry may be seen swimming in schools near the water surface. They can be scooped out with a fine mesh dip net, placed in pails and transferred to nursery ponds, tanks or hapas. This procedure for fry collection is described later.
Great care is needed since fry are delicate at a young age.
Visibility from the water surface should extend to a depth of only 25 to 30 cm, and the water should be a rich green color. The number of fry should be reduced by half if no supplemental food is given. Phytoplankton density is maintained as above. In this case, twice the number of brood fish are needed, but more fry would be produced. Replace broodstock at least once a year.
