This is the money facts that most investors would liked to figure out :
Spawning :
Male dragon fish mature earlier than females. Most male fish mature at 3 - 4 years and female fish at 4-5 yrs. our experience in spawning the fish in earthen ponds shows that spawning in the population takes place throughour the year. about two to three months before spawning. the fish select their partners and for pairs, whereupon the pair starts to display the unique courtship behaviour of dragon fish. Initially, the couple swim in circles, with the male trailing the female. This behaviour is easily visible in ponds at night with the assistance of s strong spotlight. About one or two weeks before spawningthe wo fish swim side by side, and there is a lot of body contact between the pair. Feeding drops drastically towards the time of spawning. Immediateely after spawning, the male picks up the fertilised eggs in his mouth n broods them until the eggs hatch and the larvae develop into free-swimming fry. In farming practice, the larvae, still with their yolk sacs, are removed fr the father's mouth approximately two weeks after spawning. Removal of theeggs is carried out during a physical check for brooding males.
To release the eggs or larvae, the mouth of the brooding male is gently prised open. An average of 30 to 35 larvae can be found in a single brood, with the maximum recorded for red dragons being 62 and for gold and green dragons 93 each.
Research by the PPD with a commercial farm showed that abt 5 - 17% of the male spawners in a pond can be found brooding at a single checking operation, the average brooding rate being 12.4%.
By implanting an electronic microtag into selected males, PPD researchers could follow the spawning performance of individual fish. in a two year period, it was found that abt 30% of the male spawners incubated eggs or larvae in their mouth at least once, with the maximum being five times. The male fish which brooded five times produced a total of 188 larvae in that period. This is also the same fish found incubating 62 larvae in a single brood.
The average interval between consecutive broods ranges fr four to eight months, with the shortest interval being only 80 days.

# hmm...the key point to successful arowana farming is besides god giving that we chose the right couples, are as below :
1) those arowana needs to be feed properly.
2) Water quality is utmost important, else the male will tends to swallow or eat the eggs.
3) needs someone to really monitor the behaviour of the fish n make sure that correct timing to harvest the eggs.
...one thing for sure that u will have problem if u rent pond wt ppls is
these two needs to be careful :
they can easily take the larvae n not inform u.
they will stingy in feeding the fish.
more profitable if u just buy land, korek ponds n pay fortune to get license n rent the pond...
