Aquaponics 21: Scud Trap

Hello all,
When I added the three small grow beds (see here for details), I also snug a small sieve under the outlet. I wanted to see how much detritus, etc was carried along the system.

Yesterday, when I remembered and checked the sieve, it turned out that it had acted as a great Scud (Hyalella azteca) trap. Apparently the pump carry the scuds along the system and they've survived without problems. The sieve held about twenty fat scuds.

I left the sieve on a shelf for ten minutes and it turns out that ten minutes is long enough to turn live scuds into delicious (if you are a fish) dried scuds.

So if you do not want scuds in your tanks, just leave them in a sieve for ten minutes, and then you are set. The fish ate them with great glee. This might also be the trick to use with slow eating fish (e.g. Betta Splendens (or Siamese Fighting Fish), giving them a chance to get some healthy live food.

All the best,
