Allows for longer development and larger hatching length of 4mm.

After hatching, larvae can still hide in the mouth for protection and use up their yolk.

Allow gut to develop before first feeding.]]> 2022-02-07 04:45:28 UTC https://padlet.com/200250451/v0gbi36tf84bo7qr/wish/2032275753 20012186 https://padlet.com/200250451/v0gbi36tf84bo7qr/wish/2032277755 Types and amount of vitamin needed to be added depends on other dietary factors.

Tilapia can survive in pH ranging from 5 to 10, but optimal pH is between 6 to 9. 

Low pH increases ammonium (NH4), while high pH would increases ammonia (NH3).

Rearing temperature affects how early or late the larvae develops and starts feeding.

At 24°C onset of feeding occurs at about eight days after hatching (12–13 days post-spawning)

At 30°C feeding initiates at four days (8–9 days post-spawning).

Even though the fry still possess yolk reserves these are inadequate to meet all the growth demands.

If initial feeding is delayed even by a day, the growth of fry may be sub-optimal and the fry will be small for their age.
