How do I prepare wild mosquito larvae to feed fish?
So in my backyard we have some bins that were left out upright and have collected some rainwater - naturally, they're also harbouring a bunch of mosquito larvae. I've heard about people culturing mosquitoes to feed their fish and collecting them from their backyard but I've never tried feeding my fish wild live insects. I read that it's a good nutritious treat and am willing to give it a go!
I was thinking of doing the following steps to prepare the wild mosquito larvae for feeding:
1. Netting them out of the bin of water that they're currently in, either with an actual net or by straining them out.
2. Rinsing them off in tap water and picking out any non-mosquito particles.
3. Putting them in a bit of water in an ice tray or something and freezing them.
4. Taking a bit of the frozen larvae later and thawing it to feed the fish.
I want to make sure that feeding that kind of stuff won't harm the fish. We don't use pesticides in our (suburban) backyard so I'm not concerned about exposing the fish to harmful chemicals. My bigger concern is whatever sort of parasite or bacteria or whatever could be introduced to the tank, which is why I was going to freeze them before putting them in the tank. I understand that fish in the wild would eat this kind of stuff, it's just that my aquarium fish would not have been exposed to wild insects before, which is why I'm trying to make sure it's safe to do.
What do you guys think? Is this a good idea? Is there something I should do differently to make sure my fish aren't exposed to any strange pathogens or whatnot? I was going to feed them to my tank with swordtails, guppies, boesemani rainbows and corydoras first, as I'm sure they'd all enjoy such food, and then if that went OK for them (and if the stuff sinks, which would be good for my plecos), I would start feeding them to my tank with L134 plecos and lambchop rasboras.
Let me know your thoughts!
