Tilapia - Separate Tub

Catching all mature Tilapia and put them in separate tank. In main tank only fingerling, and more fingerling to come. Holding them in this smaller tank make it easier to catch when needed.
This tank is connected to main tank via a 20 mm PVC water bridge, this will ensure water circulation and a pump will feed this tank water to growbed hence taking ammonia away from it.
Water is shallow in this tank, waiting for rain to get it higher.
Those Tilapia constantly trying their best to jump out. They will stop doing so after few hours in this tank... probably due to new surrounding prompt them to do it.
Above how my present Aquaponics arrangement looks like.
These fish are very healthy and the best part is I know what exactly they feed on..
A short video, while I am at it.

Tilapia Breeding - Fresh Batch of Fry Another Day

Since these fingerling already capable of surviving the main tank I decide to move them over there.
I was hot really hot.. something like noon over here.. catches all the fingerling with a fine mesh net so that they are not injured.
Hold temporarily in a basin before putting them in main tank.
Those above fingerling is from : Tilapia - Breeding Part II. They should survive the main tank.. some earlier batch made it. There are no more Yellow Tail Catfish in the tank so they will be fine.. Tilapia.. don't eat young ones.. well at least that what I though..
That's mum .. its easy to tell.. once you see any fry around .. disturb the water a bit, they will head for safety.. and usually in mum's mouth.. Then carefully catch her.. and place in the nursery tank.
Took me sometime to catch her, and just at the point of catching.. she spit out her young. The fry is easy.. in no time they will be in the nursery tank.


One way to see which Tilapia is carrying fry or eggs is during feeding time... try feeding them slowly.. see which of those in the breeding tank don't eat.. do this few times. You will know .. that one is carrying eggs or fry.. then just monitor.


Don't catch mum while they are carrying eggs unless you have eggs tumbler to take care of it. Its best just to let it be.. after all its more natural this way.


BTW mum will retire in to the main tank along with her fry.. once big enough.. I need to catch another female to take her place.
