Proper way to cull a fish?

[packer43064]

I plan on breeding some fish soon (marbled crayfish...I know not a fish per se) and want to know the proper way to cull fish.

By proper I basically mean most humane. I've bred Convicts and Blue Acaras before and some died or I gave them away. Didn't have to cull and fish just because it looked a bit different.

Freeze them? Clove oil?

Give them to me :c

Humane to you, or to the fish?

The least painful way. A bullet to the head would be better than no water while being in the desert for 10 days.

Depends on the size. For small fish blunt force trauma. I usually put in a bag, and swing against a wall hard. They die instantly. I know other people who put them in a food processor.

For large fish I find a sharp spike to the brain is quickest, as some one who does a lot of fishing I know how to do this properly and fast.

Quickest is best.
OP, be prepared for strong words with this taboo subject. I have found that giving them away is always the best way.
As far as crayfish go, if they are small, they can be feeders to larger fish...

Processor....

If you're breeding for feed, just freeze the crays once they reach appropriate size.

For crawdads I think giving them to friends that have big fish that eat them is best.
If it is small enough I put in garbage disposal. I know it sounds disgusting but is quick. Big fish I will put in a cooler of ice water with a whole bag of ice. Medium I put in a Tupperware of tank water and put in the freezer.
