Hi!
The best organic material are nettles. Not too much in a small bucket.
I would never ! take all the stuff through a net, you will get too much rubbish with.
No, the mosquito larvaes need to breath air, therefore they come to the water surface. I take a bucket with fresh water with me and an anthemia sieve. When I see the larvaes hanging under the water surface, I make a quick movement with the sieve through the water at the surface. Then I get them and put them in the fresh water bucket.
Than I wait a moment for the remaining larvaes in the “old water balcony bucket” to come again to the surface and the same procedure again.
When I have caught enough for the moment, I take the fresh water bucket to the bathroom and pour the water through the sieve. Than I wash the larves under the moving water in the sieve. Then I feed them to my fish.
