Lysmata from Singapore (L.boggessi)

[Luis A M]

These shrimps arrived from Singapore,as L.wurdenmanni.
I wonder if they are real wurdemanni peppers,or some other Asian species.
If they are,they must have been captive raised there

[EasterEggs]

That would be interesting. My LFS had some captive bred boggessi Peppermint Shrimp in recently.

[Luis A M]

Now that the shrimp have grown and began producing eggs,it is clear that they are not wurdemanni,since the eggs are tan coloured (or pinkish brown).They don´t have saddle marks and the telson is different to those of Atlantic species,as published by Rhyne.It is red,with bold white lateral margins,like grabhani.In the past I have bred and raised this same shrimp,and it was also reportedly coming from SE Asia.
How could we ID this shrimp?.What peppermint shrimps are being found in Singapore?.Are they being raised there?.
I will take new better pics some day

They sure look like boggessi, however I'd have to get a look at them or better yet compare DNA sequences. ORA is rearing boggessi, perhaps someone imported them to Singapore and they are rearing them as well.

No,Andy,they are not boggessi.Eggs are pink and uropods are red with a white margin.
I have to take better pics.What you need for IDing,a preserved shrimp or a molt will do?
Do you know tables/illustrations of SE Asian Lysmata?.
Perhaps Junkai could tell us about peppermit shrimps of the area that would show in Singapore stores.

[spawner]

Interesting. Pink eggs. Entire shrimp would be nice. In 95% ethanol.

[Luis A M]

Checking a LFS in Miami,Fl.I found that the peppermintshrimp they are selling look exactly like these Singapore Lysmata.Until now,only L.boggessi could be seen here,and boggessi was in fact the most frequently peppermint shrimp exported worldwide.

[Luis A M]

And these shrimps came again to Argentina,this time from Sri Lanka!.
The whole lot is uniform medium small,as if they were captive raised.Pale coloured with dark tail,like boggessi.But uropodes are blue with red tips.And the ovary/eggs are pinkish brown.
Andy R."Spawner" says he could perform some DNA assays to find out what species this Asian pepper could be.

Interesting, I will be interested in knowing what you find out from Andy. A LFS close to my home ships a lot of Lysmata Peppermint shrimp from Florida that are very small, not much larger than an inch long, and they look a lot like your images. I will have to get a picture of them next time I go to the store.

[Luis A M]

See that boggessi has dark uropods and green ovaries.

[Luis A M]

My first shrimp spawned and eggs were not pink,but olive green,same as boggessi!
Could this mean that American boggessi are being bred in S.E.Asia?
I am waiting for the results of the DNA profile of this shrimp,which will be the final word.

[Luis A M]

The eggs hatched into typical peppermint zoea.Next spawn was not olive green but tan! .and another shrimp also produced tan coloured eggs!."Tan" could also be defined as reddish brown or orange.And they look pink when seen thru the reddish carapace.
So a character I imagined so fixed and taxonomically sound like ovary and egg colour can just change in the same individual from spawn to spawn!.
In the original description of L.boggessi,Andy R."Spawner" describes the eggs as "olive green".But recently he stated (pers.com.) that they can produce "tannish color eggs".Andy said above in this thread,that he thought that my pics showed L.boggessi.
I sustained they could not be boggessi because:

A-eggs were pink,not olive green.Not a valid difference any more.
B-Telson (originally described as "dark blue to blackish") was decorated in red,blue and white (see pics). But it is mostly dark,contrasting with a light body.
C-They come from Singapore/Sri Lanka.Meaning that if they are real boggessi,they are being captive bred there.

The final word on the subject of this shrimp ID,will be given by Andy who is currently checking the DNA sequence of my shrimps.

[Luis A M]

Time kept running and I am now believing they are L.boggessi being captive bred in SE Asia.
Strange that they take all the work to produce one of the least appealing of the peppermint complex.
After 3 years I feel like starting raising shrimps again.We see new nice development in this field lately.
So I dusted one of my old Rhyne´s tanks,collected some newly hatched zoea and put the old thing going.
They look like every peppermint zoea.Z2 at 2 days.

[Amie]

Excellent, I am glad you are raising shrimp again.

[Luis A M]

Sure,I was missing the old shrimp game
I have some Z7 at 17 days.

[Luis A M]

Z8 (pleopod buds) at 19 days.But only some few.
I just collected a large number of newly hatched for raising.Will call it run 2.

[Luis A M]

Run 1 produced 5 post larvae at around 30 days. They look like boggessi juveniles indeed.Some day we will confirm that this west Atlantic species is being captive bred in Asia.
And run 2 is doing great,many zoea keep growing!

[Luis A M]

LOTS of run 2 larvae keep growing at 23 dah
Perhaps because they´re rather crowded,some show delayed development .I can see Z6,Z8 and Z10

[Luis A M]

And run 2 started settling at 28 dph
I removed the first two post-larvae to the grow-out tank.MANY more will follow!
While run 1 juveniles are growing steadily with 0% losses.

[Luis A M]

And they keep settling!About 10 post larvae every day

[Luis A M]

Today I collected post larva # 100,at 46 dph
Metamorphosis has been proceeding every day since 28 dph.Few zoea remain now.

[Luis A M]

A shrimp of run #1,spawned today,even if not fully grown yet.
74 dph and 42 days after meta.

[Luis A M]

And they hatched,closing the life cycle.82 dph and 50 days past meta.
And now one of run #2 also spawned.At 62 dph and assuming it was the elder juvenile,at 34 days past meta,maximum.
This is amazingly fast.They roughly settle at one month and start breeding at two!
While other larvae took up to 2 months to meta.I still have one unsettled zoea of this run.Possibly an abnormal one that will not settle

[Luis A M]

Final count for run # 2 is 117 juveniles!.

[Amie]

Sorry I haven't been following this, I thought I had selected to receive email messages when you posted....anyway...

Are you saying that they are settling at 28 days?!
