I thought AI stood for artificial intelligence.

lol,it is also artificial insemination.

Congrats on what you've accomplished. So what can you do with this data? Can you speed up the process of getting them to the settling stage sooner?

Well,I´m not sure if speeding the settlement of amboinensis would be advantageous at all,assuming it could be done
The natural history of this shrimp seems to be to remain long time as a larva,grow to be giant larvae and then settle into a big,commercial size shrimplets.
And it seems these giant larvae are not more delicate or difficult to raise than small shrimps,so having them settle before or after is about the same.

I need to go through this thread again to understand all the lingo Luis uses to get better educated.

Just go past the post larva pic and you will see the Appendix Interna and it´s function,and some terms being explained.

 

[melev]

Oh. As I stated before, I don't know nearly enough to be of any help at all.

The idea is to reduce the number of "marking time" molts. Sometimes the larvae will molt because they have to molt, but they won't have gotten what they needed (nutritionally? environmentally?) to move to the next developmental stage with this molt, so they are stuck at the developmental stage they were in previously. If you can keep them on track to change developmental stages with each molt, the time to settlement will be reduced.

Well put,Andy! A healthy larva changes stages at each molt.
A sick,or weak larva molts keeping the previous stage,it "marks time"(they can´t avoid molting).It´s like students having to repeat a course after failing a test.
But what happens with amboinensis larvae from 70 to 140 days?
Besides growing,do they have morphological changes or not?
In the first case,we´d have lots of further "mini"or "sub"stages(but stages after all).In the second we´d have technically "marking time".But not the "bad"marking time explained before but physiological,"normal"marking time.
Fascinating subject for biologists,but of little practical value for hobbyists;after Z14,larvae will grow until they become 1 inch monsters at 140 days and then settle.
With six larvae instead of one,normal settling time will be better determined.

foods?

Awesome! What are you feeding them at this point?

Same food since day one:Otohime B1 and bbs.

 

[GreshamH]

crushed up B1, or whole?

 

[Luis A M]

Whole,otherwise I´d used "A"
Unlike fish larvae, shrimp zoea can grab large pieces of food and chew it into little pieces.
They are also taking algae pieces came with the water flow.Dunno how nutritious,but they love it!

 

[Luis A M]

80 days.Two Z14,18mm long,pereiopod 5 measures 25mm.
AI seems more developed.
And four Z13.

 

[Elmo18]

Go Luis!!! Amazing stuff, to say the least.

Best,
Ilham

 

[Luis A M]

Thanks,Ilham!

Whatever
Anyway,the six larvae are 90 days and are still two Z14 and four Z13.Marking time,obviously,yet still growing.Large Z14 are now reaching 20mm.

 

[Luis A M]

100 days
Lost another one probably because of system malfunction.
All five are Z14 now,though one is larger and seemingly more developed than the rest.

Are you saying you need more space in your gallery to post a few more pictures? Send a PM to DgenR8 and see if Larry can help you with that.

 

[Luis A M]

That was long ago...I did send PMs asking for more space,without success...I now have an acct in Photobucket.com.Thanks anyway
If you have better access to the new mods of this forum,I also requested in vain to edit my thread of some duplicated post.

 

[melev]

I'll ask for you, but that doesn't mean anything will happen. Can you give me a list of all the redundant posts in this 8 page thread? What you do is right click over "open this post in a new window" and then click Copy Link Location, and paste that URL in a reply. If the list is substantial, the MOD will be more likely to do it than if they have to go through 8 pages looking for them.

We have bigger fish to fry here on RC daily, and the mods tend to stay busy putting out fires.

 

[Luis A M]

Thanks.I also posted to the administrator without reply.I now sent it thru the "report this thread..."box.
Page 7,Jul 16,:his is the 14th zoea at 76 days.Pleopods are functional and covered by setae all around,about 40 setae in the exop.The endop.now has an AI.
Again in this pic,the two uropods can be seen.The smaller is the endop.and the little spur in it´s left border,the AI.


The first of the two posts should be erased.

Kevin took care of that for you.

Louis,

Is it fixed? Just checked my email and got the post report you made last night and want to make sure I'm not going to end up removing the wrong post

BTW while Erik and myself will get any post reports, they go to our email. In my case, while I can easily surf RC from the lab I don't check my personal email from work...so if need something quick just PM me as I'm normally on RC at least once a day if not more

You did remove the good one
See the phrase:

Again in this pic,the two uropods can be seen.

The word uropods should be replaced by "branches"
