great news.  I've been trying to breed my riffles for a couple of years.  last year only 2 (of 10) got berried and I didn't get any larvae - havn't seen a berry since!  Wishing you luck with bubbas.

Grubs if you can raise the temp for a day or two to around 30 I have about 10 berried girls had a few very hot days a couple of weeks ago where the temp in the tank hit 30 after each of the hot days I would find a few more berried girls they seem to like the high temps. I had the same thing as you last year very few girls berry still have the same in another chilled tank no berried girls.

so worth a try if you want some berried girls.

I've got 3 berried now.  Feeding paramecium (you can see the "trails" in the pics).  Have begun a daily watch for larval release as I'm fairly confident these will need transfer to salt to develop.

Nice work. I agree that they will likely need salt water to develop. The eggs look quite small, amongst the smallest that I've seen on riffles.

I thought I might have missed the big release but the shrimp pictured in my previous post ^ Nov 14th are still carrying the eggs (that look to be well matured).  I cant make out the detail in the eggs (phone camera) so cant tell what the pale parts vs the dark brown parts are.  I'm still hoping to harvest and raise a bunch in salty water but that assumes my tank inspections coincide with egg release!  I was surprised they take so long to mature.

Pale flecks could be eggs that didn't fertilise but I would have expected them to break down or fall off.

I've been checking the tank by torch light every couple of nights since November -  what a waste of time lol!

Finally!  I've harvested them to a coffee jar and have started raising the salinity by adding 20ppt salty green water.

Awesome ..... I wouldn't mind a lesson in raising the salinity with salty green water?

Whats the method?

And how long do you think they need in that before they can go back to fresh water?

Well last night they went off with a bang.  During the day I did a 1/3 water change (rainwater + DIY GH booster) and I also noticed the sponge filter was running slowly so I upped the air and therefore the flow in the tank.   This seems to have simulated  a rainstorm event resulting in significantly more larval release.

So I siphoned them out into a 50µm sieve and then into a moccona coffee jar with some of the tank water.  Over the next few days I slowly add salty greenwater culture a little at a time.

For DAS I increase the salinity to ~20 ppt.  It takes about 1 month for them to metamorphose into post-larval juveniles.

For Riffles its an unknown quantity - lots of people report breeding big egged Riffles without salt in the tank with the parents.  I've not been successful over a couple of years and the literature says they need estuarine conditions.  My shrimp from livefish.com.au originally may have come from locations closer to salt water than some other peoples shrimp.  So I'm trying some salt at a number of concentrations. I will split them over multiple coffee jars with different salinities and hope one is successful.

The black sticks are irrigation risers connected to air lines as a convenient way to put a few bubbles into the jars.

Ohh congratulations!

I noticed you mentioned feeding paramecium to your rifles, would you know of where I might get a starter culture?

no luck with mine.  The larvae lasted longest in 15-20ppt salt water but the food (algae) clearly wasn't right.  I have more berried so should get another go at it.

Hmm @Paul Minett I wonder if over many generations the success rate will increase? If you end up with riffles that breed better in fresh water then it would be very cool

@Grubs good luck on the next round!!!

possibly some of mine have come from places a long way from any salt water maybe that has helped.

      Blue eggs RCS
      By Lovlea
      Hi new shrimp owner here. I’ve read and done lot of research. I’ve had them for only a short time before the 3 females I have became berried all at once. One is an orange and she has a full batch of yellow eggs. I have a clear, with red saddle and tail and a little yellow. She has a small 4 eggs batch (assuming because she’s new to the tank or a new mom) and then this beauty (as seen pictured. When I read about egg color they are yellow or green. Can someone tell me about these blue eggs? The male is all black.

      Berried Tangerine Tiger Moulted with Eggs?!!!
      By Crabby
      Okay, so the title pretty much says it all... One of my berried tts just moulted, and she left the eggs in the moult. What happened, and why? 
      I'm going to try to save the eggs with some sort of extraction, and I'll be very careful. She was pretty far along. I think I'll use the net over bubbler method. Does anyone have experience with this, and particularly the extraction? I won't do anything until I have some idea to go off. 
      Thanks in advance.
      Crabby
      Oh and the moult is under like 2 hours old. Wasn't there when I started watching a movie, was there when I checked back after.
      Going off this video: 
      Hoping the process will be similar.

      Lowkeys B18 Power Protein
      By KeenShrimp
      I have been trailing this product for about 8 months now:
      Ingredients: Lactic acid bacteria, crustaceans calcium, reduced maltose, mulberry powder, yeast
       
      I cannot argue with the fact that it increases my berried ratio among females after feeding. I sceptically attributed it to the protein component only initially, but trialling one tank on protein- high Ebita Breed Hinomaro bentou and another tank on B18, I still find B18 has a more pronounced effect on fertility.
      Whether it is potentially the Lactic Acid Bacteria strain used, the highly absorbable form of calcium used, the digestability of the yeast protein or a combination of all above, it appears to work.
      Dosage: Once a week, small amount.
       
      Highlights:
      - very little is used, so it lasts a long time as it is very concentrated.
      - the shrimp are attracted to the food supplement when put in the tank.
      - it completely breaks apart into a fine particle mush so that all shrimp can have a bite of the small portion dosed
      - it indeed does increase berried rate
       
      Concerns:
      - not available for purchase in Australia yet. Available in Japan, Singapore, Hong Kong.
      - possible water contamination potential if too much is dosed in nano tank.

      oxytetracycline dosing

      By jayc · Posted

      Ah yes. That was the injectable form of oxytetracycline. Each mL of the injectable form contains: 100 mg oxytetracycline HCl, 5.75% w/v magnesium chloride , 6 H2O, 17% v/v water for injection, 1.3% w/v sodium formaldehyde Sulfoxylate as a preservative and q.s. with propylene glycol. Basically, it has additional compositions in it. 1000mg might have been the dose recommended for the injectable oxytetracycline, but if you have the powder form then follow the dosing rates as recommended on your bottle. Hope that clears it up a bit.     As for doxycycline and it's use to treat short antenna ... I cannot comment on whether it will be more effective than oxytetracycline or not. But if you do use it, only try one at a time. Is bacteria even been proven to be the cause of "short antenna disease"?

      oxytetracycline dosing

      By beanbag · Posted

      14 April 2015 -  Update based on experiences of one of our SKF members. Unfortunately for this shrimpkeeper it was too late to save these shrimps, but hopefully this experience will help someone else. 250+ shrimp were lost before the bacterial infection was halted.   A vet was consulted and he eventually ended up contacting a senior lecturer of aquatic animal health at University of Adelaide school of veterinary science. He stated that bacterial infections being internal or external are almost always gram negative in aquatics and recommended using oxytetracycline at a dose rate of 1000-2000mg per 40ltr of water.   Dosing method: Oxytetracycline is available in 2 forms. Powder and injectable. The injectable form was used as it is a stronger form. This meant that we could use less to obtain the required dosage.   Dosed straight into the water column at 1000mg per 40ltr of water.

      What?! Can you point me to where you saw that please?   If in doubt, Always follow the directions on the bottle.

      oxytetracycline dosing

      By beanbag · Posted

      What is the recommended dosing for oxytetracycline?  The sticky thread has a mention of " 1000mg per 40ltr ", but I don't know if that refers to total amount of powder, or active ingredient percentage. I live in USA, where oxytetracycline is not as common, but I was able to obtain a bottle of powder.  On the bottle, it says [calculated out to] 75 mg / 10 gal, which is a wayyyy lower value.  Also, the manufacturer / distributor won't tell me the fraction of the power that is active ingredient vs filler. This is for a Taiwan Bee shrimp tank with pH 5.5 and Gh 5, in case that matters for the effectiveness of oxytet in these parameters. I also have doxycycline available if that is equivalent / better. It's to treat that "short antenna disease" in one of my tanks that seems to show up once every few months. I've already dosed with Maracyn 1 (erythromycin) and 2 (minocycline) and they didn't seem to work.
