Suspending bloodworms / mosquitoes ?

Summer time in England offers plenty of bloodwoms and mosquitoes eggs and young larvae, which, once of descent size, I feed to my newts. Come winter and the supply runs out.
Any knowledge out there on freezing or refrigerating eggs or hatchling bloodwoms / mosquitoes to be re-started in cultures for the cold season?
Thanks
Dewy

Bloodworms can be found in the winter too. They just don't reproduce very well then (or at all?). I don't recall ever seeing midge/mosquito larvae in the winter in the British Isles. There's no way you could refridgerate the eggs of either - particularly bloodworm eggs since these are suspended in jelly "tubes" that are held in place by a very thin "string".

Thanks for replying, John.
How do bloodworms and mosquitoes over winter in the British Isles?
In summer time I collect bloodworm jelly egg packs and mosquitoes egg aggregations from the outdoors, plunk them in a jar of water, they then hatch and grow.
Surely it should be possible to keep them suspended in refrigeration in their natural winter phase, shouldn’t it?

As far as I'm aware they do so as larvae. Bloodworms definitely still reproduce in the winter, albeit slowly, but I think mosquitoes go into a sort of "wait for spring" phase.

I'm failing to see the point here. Even if you kept the eggs near freezing they would still hatch in a few weeks I think.

I’ll explain myself:
I assume the eggs/larvae suspended in refrigeration will resume normal rate of growth once returned to normal temperatures.
The benefit would be prolonged supply of starters to the cultures, perhaps lasting beyond the season of plenty.
Can you see my point?

Yes but if they won't/can't reproduce in the winter then it's an extremely limited supply.

    @Jokerjay, as in water dogs do you mean axolotls? i suggest very heavy research and a fully cycled tank before even considering purchasing one

    i highly recommend “buyanaxolotl.com”- ive purchased from them and received a beautiful animal for relatively cheap, in great condition, and excellent shipping precautions. the breeders are a couple living in georgia (i believe, don’t quite remember) and they’re fantastic. sometimes their website contact page doesn’t work, so i’d probably try just emailing them. good luck and happy hunting!

    Hi all I'm new here I'm just looking some advise on cycle witch is currently driving me insane . So we are week 8 I'm dosing daily with 4pp of amonia and for the last week has been dropping to zero witch I no is good. But my question is my nitrites are sitting at between 0.50 and 1.0 PM and nitrates are between 10 and 20 and neither of these seem to be dropping. I have done 2 40% water changes a few days ago and no change the only thing I can think of is I didnt use the seachem stability stuff which I have now ordered but surely that shouldn't have much difference this far into cycling

  • ytz13513:
    Dropping ammonia with rising nitrate and nitrite is good. It means the nitrifying bacteria is working. You just have to remove the nitrate from the water doing water changes. The level of nitrates is high and the nitrate is also high. The nitrite will be converted to nitrate using the beneficial bacteria and you can add them using quick start or allowing them to naturally grow in the tank. The latter option will take longer. The nitrate can be used by plants, so live plants can decrease the levels, but I would do a water change to get the nitrate at a level that is lower than 5 ppm. 5ppm of nitrate is natural and a good place.

    New here. hope this is the right place to post my question. I had 27 axolotyls aged 2-3 months old. main food has been finely chopped up bloodworms. no problems. I decided to introduce earthworms from my earthworm compost bin for variety. I finely chopped up 4 small earthworms and fed them to the babies. Within an hour 20 of the babies were dead. The remaining 7 (the smaller babies) survived and are now fine on bloodworms. Any ideas why the chopped up earthworms killed many of the babies?
