Anyone ever successfully bred red nose shrimp? My female rednose is pregnant and I thought I give it a try in hatching the eggs. The female is carrying the eggs and how do I go about hatching them now? Appreciate your sharing. :D

Hi Kross, congrats on your pregnant Red Nose! I haven't yet heard of anyone successfully breeding them though that doesn't mean no one has. It's to my understanding that most, if not all Red Nose are wild-caught at this time. Hope someone could relate their experiences though.

The larvae will need brackish/saltwater, but that's about all I know. So *perhaps it's a bit like using the directions for raising Amanos? That's just a guess though. Please keep us updated on your progress and detail any steps you take as the eggs mature/hatch. Maybe you'll be among the first to succeed?! How many Red Nose do you have? And for this species, is it fairly easy to tell the sexes apart? Best wishes. :)

Hi GB, Thanks. I have 9 of them. 2 males and the rest are females(I think). I differentiate their sexes by its nose and size. Male has a slim body and red nose whereas the female has got colorless nose and broader body. I compare their sizes using their total length. That way, you'll get a pretty accurate sexing. For instance, compare 2 shrimps with approximately the same length. Once you got that, move on to check their body size and nose. :D However do take note that under stressed conditions, the male will easily loses the redness of its nose. But you probably won't go wrong with the body size. :)
Btw, the male usually will have a pretty long nose if it is not damaged. lol

Actually, my problem now is how to get those eggs hatch in brackish or saltwater. With the female carrying the eggs and put it in brackish water? It will probably kill it?:huh: Or "collect" the eggs and put them in brackish or saltwater to hatch? Then again, how to collect? lol
Hmmm....guess I'll just experiment it. :D

My guess is you have to put the female in weak (compare with full strength seawater) salinity aged green water days plus sponge filter days before she release her babies.

After she releases her fries, got to acclaimise her back to freshwater, same thing before putting her into salt water.

Some people tried to breed Yamato, the babies were released in freshwater, they died within 2 days.

Good luck, keep us update.

Good luck for your project. Do note the brackish water you are going to put the female in must not be too saline either. (No one knows the exact amount though, its a risk) However too little the babies will die too. :confused:

Wish you best of luck and may you succeed! :D

Hi Kross, I don't envy the job you have before you - yups, a lot of hard work! http://img.photobucket.com/albums/v376/Catgravity/ZMisco/Rollupdownboulder.gif Plus you must be nervous with us looking over your shoulder, hehe. :D

If you were to follow Mike Noren's (Mikes-machine) method of raising Amano fry, the adult does not need to be put in brackish/salt water - the Amanos in nature supposedly release the hatched eggs in freshwater at which time the larvae gets swept out to sea (saline water). So basically, when the larvae hatch, you can use a flashlight to "gather" them (they are attracted to light), then straw them up (or use a clean turkey baster) and drop them into saline water. Of course the million dollar question is whether Red Nose breed like that, but it could be worth a try since you are not endangering your mother Red Nose since she stays in freshwater.

Ok. From what I see there are a couple of ways to do it. Here are 2 options that I'm considering.

1. Isolate the pregnant female in another small holding tank. (My cycled unused phototank. :D ) Let the famale release the fries and remove the female. Then I will slowly increase the salinity (how much? :huh: ) of the water and hopefully the fries survive or,

2. Isolate the pregnant female and slowly increase the salinity of the water. If the female is still alive and releases the fries, I will slowly reduce the salinity of the water when the fries are around 5mm long.

So, which should I use? Option 1 or 2? :undecided

silane

I will go for option 1, if you don;t want to stress the female, put it in a MATURED separate breeding tank, let it releases the babies. Upon fully release, remove female, increase salinity (you pick a salinity level, I guess at least 50% of full marine salinity is needed) over many days.

Someone attempted to breed yamato said his fries start to die on second day in freshwater, but that maybe different case from red nose.

Keep us update, this going to be interesting. :drummer:

hello:

Here is some advice. I just managed to raise the red nose larvae to little shrimps about 5 mm size to tis point. In the Noren article, do not dump the larvae into full marine water. I did that twice and nothing survived. On the third try I gradually increased the salinity by 2 ppt per day until 17 ppt. I left it at 17 ppt but since I had an open tank and left for a short vacation, evaporation resulted in a final salinity of about 24 ppt. At that time, the larvae were 1 month old and began to change into little shrimp. I left it at 24 ppt for 1 week until all the larvae had changed, about 30 -40. I gradually decreased the salinity by 2 ppt per day until 0 ppt. When larvae, I kept the light on 24/7 to grow algae and used liquifry 1x per day which seemed to be enough.

the only problem now is what do you do with 30-40 shrimp when grown.

Good luck.

Hockey Shrimp, welcome to the forums and congrats on your success story! Glad you shared your experiences, it will be most helpful here. :)

Kross, is everything still going good with the pregnant Red Nose? By the way, thanks for the helpful explanation of how to tell the difference between the male and female. It sounded a little like you were talking about Pinocchio. :joking:

Yes, as Fruitpie says, this will be very interesting indeed! :cool:

Hockey_shrimp,

Welcome to the forum, and nice to know that you have succeeded in breeding red nose shrimp.

What is the tool that you use to measure salinity? Were you are using marine salt mix or seawater?

Welcome to the forum and thanks for sharing. :)
Question:
When you mention larvae, I assume that the female shrimp has release them and was remove from the tank before you add marine salt? Please elaborate. Thanks. :D

Hockey_shrimp
28th May 2005, 01:49 PM
Yes. I let the female release the larvae then removed the female from the tank. I didn't add the salt to the tank but changed the water gradually replacing with, I think water that was 1/2 strength marine water that I mixed and aerated for 24 hours before adding to the tank. But I replaced enough to go up by 2 ppt each day.

I did a daily water exchange until I got up to 17 ppt then probably every other day since the liquifry seemed to foul the water pretty quickly. I'm not sure adding the liquifry did anything, maybe help to grow the algae. But you will notice the larvae stay on the quarium glass a lot, maybe to feed. I let the algae grow on the tank sides and bottom (bare bottom tank). I think eventually I gave up on the liquifry. Later I tried crushed flake and freeze dried brine shrimp once in a while. i think the only thing I did different from the Noren article was the gradual increase of salinity to 17 ppt rather than dumping into full strength sea water.

Cheers.

Sorry i didn't read the other questions before replying before. I used a swing arm hydrometer and used Instant Ocean mix (both were cheap).

Hello Everyone:

Here are some fuzzy pictures of red-nose shrimp fry at about 2.5 months of age.

Hope these pictures get uploaded OK.

Impressive.

I suppose you brought them up in brackish water? For how many days were they kept in brackish/salt water?

Hockey_shrimp
12th Jun 2005, 08:29 AM
In total I would say 4 weeks in brackish water to get them to change from larvae to little shrimp then another week to make sure all larvae changed then another one to two weeks to gradually reduce salinity to fresh water.

Are you planning to breed more, sell these ones? Just curious. :D

At what day do you start to increase the salinity and what is the maximum level?

Hockey_shrimp
13th Jun 2005, 01:32 PM
I started to increase salinity the first day. I intended to increase to 17 ppt only but ended up going to 24 ppt. So the max I got up to was 24 ppt.

Wow - Hockey_shrimp. Thats impressive. I have never ever heard about successfully breeding of this little beauties. Maybe you should make an article about your journey and publish here ;) Otherwise you have to answer tons of single questions from now on :D

Nice photo shots.

It always feel good to hear another successful attempt at shrimp breeding dont you think? :D Do share your insights on red nose breeding with us. Yeah document your breeding process it will be fun.

:karate: Let the journey begin. ;)

Hockey_shrimp
14th Jun 2005, 02:38 AM
You guys are right.

I'll work on an article to document the process so ...no more single questions. I'm waiting for another pregancy to try it again. I've only done it successfully once out of three tries so it's not like I've perfected anything yet.

Stay tuned.

Of course if anyone else does it successfully in the meantime feel free to write the article.

kross
20th Jun 2005, 01:32 PM
UPDATE:

None of my shrimplet made it. :(
I think the adjustment of salinity is very critical....
Oh well, will try again if got another pregnant rednose. :)

Aww, sorry things didn't work out this time around, Kross. You're sure to improve with each try, and with about 7 females in your bunch, perhaps you'll get to try again soon! :)

Hi guys, thanks for all the tips and encouragement given but I'm afraid I'll have to put the rednose breeding program on hold due to space constraint and hassle of water "transformation". :juggle: I will definitely try again the next time round when I move to a bigger house later this year! :wink: More space!! :smug:

In the mean time, keep shrimping!! :D

Could anyone suggest how to breed them in a tank with salt water?
they dont have anything to cling on? what does those babies eat?
I lost all the babies i think...

do they need to start with freshwater when the hatch... then slowly up the salinity?

Walter
16th Aug 2005, 11:17 PM
Shrimps prefer to have things like driftwood to cling on to, I think the babies feed on micro organisms. I guess you need greenwater. No idea how to raise the shrimplets though, hope you succeed one day! :D
