winter breeding


Recommended Posts

Hello there.

How is your breeding routines going?

it have been years now , that shirmps dont breed in winter, i keep aroud 20 tanks.

Shrimps stop breeding from novemer to march.

Temp no plays role,  i keep tanks without heat and tanks with heat , also some tanks with more light and some wiht less.

I saw crs breeding in 15c,,,, and in another tank with 22 c from 200-300 srhimps no one breeding with same light.

After a  lot of research the only think that it play roles in winter is barometric presure.

The crazy is that a friend living here , he saw some breeding in winter.

The only think its in my mind is that my shrimp room dont have a good  insulation so barometric presure is the same as outside...

In house with a good insulation  aircodition can change the barometric presure, and keep it stable .

What is your opinion about breeding in winter ?

I've had 3 berried females, only one after adding a heater. Two were bloody mary, one a YKK. My YKK colony is pretty young still so first berried female from the group.

Unfortunately, a bacterial infection or something wiped out many of the Neos, including many of the babies and I haven't seen signs of the YKK offspring yet... so it could be better! 


I know many people experience slower breeding in winter. One breeder/reseller said that he put a heater in his shrimp room (small bedroom converted shrimp room - door is often open to the rest of the house with a gate to keep the pup out) which helped to increase breeding.


I don't have a shrimp room, tanks are in living space.

There is a good video about Taiwan bee shrimps not breeding in winter so it is worth watching if this is something happening to you, great videography as well?


My taiwan bees aren't breeding and I suspect that  it is because it is winter here and so it was really bad timing on my part as they probably reached breeding age as winter started, d'oh!

I think I have said elsewhere on here, but can't now find it (my bad) that my small 15L tank I started with didn't have this happen but I found my old notes and babies/berried shrimp actually didn't start to be seen until end of March (then it went crazy) so again it appears to confirm this affected that tank as well, and it doesn't seem to matter the size of tank if this is correct.

Annoyingly this means I have to try and keep these adults alive until spring, though I can hope there may be some babies soon (oblivious)??

      Keep doing this, and feeding it the medicated food. If the shrimp doesn't eat the food within a day, remove it and feed new medicated food again the next day.   You sir, are a good candidate for an RO filter. Your shrimp are not going to like the hard water in the long term.

      The shrimp is in a separate container, but it's been in there for a week or so now. I see it picking off the air stone and the sides of the tub. There is shrimp poop in the container, so it is eating, just not the food I give it. I suck out the detritus and excess food every couple of days and do small water change daily. At first I used tank water, since I don't run R/O. I use a combination of hard tap water with a little water ran through my water softener (I know it's a bit taboo to do). I don't know an exactly how to re-mineralize it to keep the shrimp from going into shock if I used straight clean tap water. I am starting to slowly remove the water from the tub and mixing it with direct tap water with the water softener on by-pass, so hopefully it can acclimate to full clean tap water. With the shrimp feeding, should I try to remove all visible signs of food and fast it for a couple days and then try again?

      Is the shrimp still in the main tank? Or have you moved it into a separate container? There should be no biofilm in a new container, and it should be hungry to want to eat the medicated algae wafer. It won't go away without treatment. The bacteria is not just on the shell (carapace), so moulting won't get rid of the bacteria.

      I've tried to feed the shrimp food soaked in the oregano oil mixture (1 drop of oregano and 5 ml of water since it's 86% carvacrol). The shrimp seems to hate the taste of any food I put in there with the mixture. It goes off and tries to feed on anything but the medicated food. I don't have any other food in the tub and took all the floaters out but seems to be feeding on naturally growing biofilm now.. I'm not sure if I am seeing any results. Should the reddish brown spots go away on it's own or does the shrimp have to molt it off? I've noticed it's been scratching itself a lot.

      Ok, thanks. I'll do that. Yes, I have the tub lightly aerated.
