The keys to producing jungle perch are:
- maintaining broodstock in freshwater or low salinity water less than 5 ppt
- spawning fish in full seawater at 28C
- incubating eggs in full seawater. Salinities must not be less than 32 ppt
- ensuring that first feed jungle perch larvae have an adequate supply of copepod nauplii
- rearing larvae in full seawater under bright light
- use of gentle aeration in tanks
- postponing spawns until adequate densities of copepod nauplii are present in ponds
- sustaining copepod blooms in ponds for at least 20 days
- avoiding use of paddlewheels in ponds
- supplementary feeding with Artemia salina and weaning diets from 20 days after hatch
- harvesting of fingerlings or fry after they are 25-30 mm in length (50 to 60 days post hatch)
- covering tanks of fingerlings with 5 mm mesh and submerging freshwater inlets to prevent jumping.
