Taiwan bee's don't breed on the winter

Recommended Posts

Two winters straight I am having this issue - basically the shrimp breed in the summer but when winters comes no berried at all among Taiwan Bees. In my mischlings I have berried shrimp all the time and I even tried putting some of the TB into the mischling tank to see if this will help, but no. Do you have any ideas what can be the cause of this, and what can be done to encourage the shrimp to breed?

I don't because the temperatury stays 22-23' C which is supposedly optimal for these shrimp. The mischling tank does not have heater either.

Does the room get natural light? Could be a difference in day length?

I have been breeding shrimp since 2012 and every winter my breeding stops usually for a few months. Every tank is the same and I have 12 tanks. 11 are in an air conditioned room  and 1 is in another room but is run with a chiller. I have a mix of natural lighting and artificial lighting, heaters are set to,23-24 and I don't do anything different at that time of year. Quite a few other breeders I know of here in Australia have the same issue.

I don't worry about it and think  its a great time to rearrange tanks , top up soils etc as there aren't tiny babies to catch out. I also like to think it gives the females a break. Even my hybrids stop breeding and they breed very well the rest of the year. Perhaps they still notice the change of seasons even though they are inside.

Could you please explain? Most sites recommend this temperature range for caridinas? 

And yeah the room has natural light. The difference is that during summer I am using covers during the day as the light is to strong and I get algae bloom if I don't. During the winter there is no need to use them.

Hi there ...

Same happening to me.. all my shrimps stoped in the winter, not the sullawesi cardinals...  I try diferents temps , more hours light , but not see shrimp affect of that?  I have about 80 crs and no babies.. not baried..  Now started the neocaridina to get eggs , also tigers...

I cant understant the reason,why  thats happen...

 

As i saw they stoped from november to april...

It's probably a natural cycle.

The females need a rest, maybe.

Winter is the time to feed them up with lots of protein (frozen Blood worms), so they have the strength for the warmer seasons.

Hi there ,

Yes its maybe a natural cycle.

But many have beried females all the year, they dont stop.

I have a friend here, keeping shrimps, his crs, now have babies.

we use same minerals, substrate,temp foods..

So what can be the " problem.

I have this problem every year so annoyingly no babies expected here for a couple more months yet!!!

This is a common problem.

Two of my Taiwan Bees got berried as soon as they hit maturity in December / January.  This is with a tank temperature of 67-70F.

It is odd how this only affects some and not others. My Bees were old enough to have started breeding months ago but as it is winter here, alas no shrimplets. My previous experience was that the berried females started March as well so it is clearly a normal thing here. I have no idea why it happens though as the tank is timer lit and heated so that is a constant all year round?

I just did a google search for yearly variation in barometric pressure, and it brought me to this page:

https://www.securevideo.com/blog/2016/03/18/global-barometric-variation-annual-maps-and-monthly-raw-data

It looks like I live in the blue region with low variations and you live in the yellow region with larger variations.

Thanks for that, I will read that with interest later! Time to do the weekly shrimp tank water change and maintenance............

      I have just done the planned weekly maintenance and 10% water change and everything 'seems' to be going very well, I saw 12 blue and 9 panda shrimps so am very happy about that as there are always some hiding (and they are small) so there must be more than that at this point. Early days yet (especially with the off parameters) with the blues only been in the tank for a week and the pandas for 2 weeks. Not seen any dead ones yet and the shrimp seem happy enough and beautiful colour and pattern, all small so must be young! Parameters were TDS 159, GH 7-8, KH 1-2, PH 7 yesterday so still a bit off the usual ideal! Hopefully these figures come down slowly in time, I used pure RO water for the water change so Tds should drop 10. I will get a different PH test kit with a narrower range/increments as the one I have measures in .5 increments over a wide range which is probably a bit much. I bought these shrimp because the sellers parameters (PH 6.8) were the closest to mine so hopefully it will work out long term. I changed my zerowater filter as well, as the old one was measuring TDS 6 so passed its best. I will definitely overnight drip acclimate shrimp in the future, not that I plan any more in the forseeable future. I will add/edit photo when available, hopefully later today.

      All done now, I drip acclimated 11 blue bolts and 6 blue steel overnight and they are now in the tank so now is just wait and see if this works. 28 shrimps have now been put in and I have yet to SEE a dead one so fingers crossed! A couple of pictures of some below; I don't plan on buying any more shrimp so plan this to be a blue shrimp tank, though if it doesn't work out I have seen some female bettas I would like, but hopefully the shrimps will work out. The water parameters are still the same as before, so a bit off! I need to sort out what foods and shrimp stuff I have in the drawers and cupboard tomorrow as it's been a while, hopefully I find a shrimp lolly so I can give them one/part of those tomorrow, and it may bring as many of the shrimps out as possible.  Fingers crossed everyone...........
