What are fish seeds?
Fertilized fish eggs are known as Fish seeds. In simple words, they are the baby fishes used for seeding new Ponds in fisheries.

They can be used in 4 stages:


Hatchling : Larvae stage where it have yolk sac hanging below from where it draws its nutrition for 2–3 days. It can't eat from outside as mouth is not formed yet!





Spawn: Stage where mouth is formed.





Fry: About ~2 cm long, now, it can eat small size zooplanktons!





Fingerling: About ~15 cm long. It is now becomes easier to transport these kinds of fishes to Ponds.
