Design of Hatcheries - Larval rearing unit
Unit 9 - Hatcheries
Design of Hatcheries
Larval rearing unit
Proposed system = 2 phase
I st phase
Stocking density of stage I – larvae = 400 Nos/l
Volume of water required = 25,000 lt.
Volume of each tank = 1000 lt
Dimensions of tank = 1.2 m x 1 x 1 m = 1.2x 1x 1
Total no. of tanks required = 25 Nos.
Survival in the Ist phase = 80%
No. of larvae recovered after completion of Ist phase of rearing is 10 to 12 days = 80 lakhs
IInd Phase
Stocking density = 80-100 larvae/lt
Total volume of water required = 1,00,000 lt
Volume of each tank = 4000 – 5000 lt
Dimensions of tank = 2.5 m x 2.0 m x 1 m
No. of tanks = 25 Nos.
