I started messing around with tilapia 2006-2010
2010 - the end of july i had to take my system down
i am currently trying to get a piece of property to set up a scaled system.
basickly i dont have a system that is running
but i want to share my last 4 years with aquaponics
air temp inside the tunnel has been around 10-12 deg c in the morning
and 25-30 in the afternoon's on sunny days.
the fish currently in this system
4/8/2011 i added 5 Kio….
4 left out of 5 and 2 are now 150mm long
and the other 2 are +-250-280… 1 died
2/9/2011 80 tilapia males only .....
only 12 left +-150-180mm…
I did the damage to them within a few days…
27/9/2011 7 off 40mm Kio and 4 off 100mm Kio…
lost 1 of the 100mm Kio
= 10 left +-200-280mm
15/11/2011 15 Kio 10-20mm into my duckweed trays ….
found 2 dead flouting ….
some are still alive and +-50 mm long…..how many survived ?????? let’s say 7 out of 15 survived
4+12+10+7=33 fish in this system…and very happy
update on plants and fish
very cold now…water temps +-12-16 deg Celsius
Morning temps inside the tunnel are +-10 deg
The fish are still eating but halve of what they did a month ago….
I find they are more eager for worms in the cold temps…
I have been feeding them a good helping of worms almost
Every day since the low temps.
As far as the plants ……
Over the last +-20 days I also have not added anything
Into the system water…but
All I have been doing is spraying the plants with brewed worm tea….
What left of the 5 litres I add into the system?
I use +- 8 full hands of castings in 5 l water and brew for +-12-20 hrs.
And then feeding the fish pellets and the worms
I found this pray mantes on my window sill and put him into my plant area...
He has stayed around for +-8 days now and he has been doing an excellent job of the aphids....him all on his own
I was using a very weak soup solution for the aphids before...slightly burning the plant leaves but....had/have to get rid of them...
I found the perfect solution....and it works/////
