Pheromone Query

Recommended Posts

Hi There, I had an idea hit today and was wondering if anyone can confirm/deny for me. I have been thinking, after reading, about how when the females release their pheromones the males go mad, as they do in other animals. I know there is the theory, and I for one buy into it, that females living/working together can tend to cycle together (bear with me ladies, there is a point here!! No offense meant). A quick question before the idea: 1. Once a female shrimp has the pheromones going on, have any of you found that the other females in the tank also get berried too? My idea, and it is a bit hair brained, is if the pheromones from one female in the tank can inspire the other females to get ready to breed, do you think if I had a female releasing pheromones in tank A and I transferred some of that water into tank B, it might inspire the inhabitants of that tank to kick start the breeding process? A bit of a simplistic idea but had to ask.

I hear where you are coming from and it does often happen that once one female gets berried others tend to follow quite quickly but I'm not sure that the water would carry enough to trigger breeding in another tank. But hey it may be worth a try you never know if you never try. Someone else may be able to tell more.:encouragement:

i thought I should just add there is something written about not putting water from one tank into another due to bacterial infection - that's why you always catch your shrimp in a net to transfer them from their water to a new tank after acclimatising them - that may be because the water comes from a different colony but I would check it out before trying it

There is a product called "breeding liquid" which is a concentrated synthetic replicant of this pheromone, you put a few drops of this liquid in the tank & everyone goes crazy. I think that this would only be useful if the females are ready to breed & have just moulted but otherwise it wouldn't really do much but send everyone crazy for a few minutes :encouragement:

For fish it works. However as Squiggle said, the shrimp have to be ready to go. Remember that mating occurs only after the female has moulted, which means that your shrimp not only has to have eggs ready to go, your shrimp must also be ready to moult.

If your shrimp aren't breeding, I would be checking water parameters, food, temp, disease ect. first to check that they are A1. Only then might it be worth worrying about trying to trigger them using pheromones. IME shrimp are more difficult to stop breeding.

Thanks for the replies. Just thought I would put it out there. Don't think I will have issues getting them to breed as they all seem to have settled in well and saddles and moulting has begun. Will look after the water quality and let the shrimp look after the rest of it. Cheers.

2+ years ago, I used and tested the benibachi breeding liquid extensively, and had great success, BUT it does put pressure on all tank mates. Never used the breeding liquid since.....didn't want to risk any forced fatalities, prefer the natural way !

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony.

      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
