One week.after I started the propagation of Azolla which I acquired from Azolla Pilipinas in Bulacan, I learned another important lesson: never ever grow it in a pond with fish.
Early today, I checked on the Azolla which was propagated in two areas – a fishpond which only had young.mudfish and native catfish, and in a net half-submerged in water.
The Azolla placed in the fishpond had all disappeared meaning that even mudfish and catfish feed on Azolla.
My son, Imman, validated that by scooping a handful of Azollaa which he threw into a pond filled with Tilapia.
The Tilapia swarmed on the Azolla and in seconds, it was gone.
The smaller volume of Azolla which was placed in a net half-submerged in water and protected from the fish had multiplied more than 20 times.
Today, my son, Imman and farm help, Verver, started transferring some of the Azolla in another netted area.
What I plan to do now is to propagate the Azolla inside fishnets in the ponds and just scoop it daily to be fed to the Tilapia.
When that happens I will not only be saving on feeds but it will also allow me to claim that I am raising organic Tilapia.
