Raising Sexy shrimp

[Luis A M]

well if you can remove and invert the lens thatÃ"šÃ‚´s something!.Better than my Cybershot and itÃ"šÃ‚´s stupid 5" delay that I couldnÃ"šÃ‚´t so far override!

Yes,you should be feeding bbs.Though they have reserves to molt to Z2 unfed,it was shown that early starving jeopardizes their future.Shrimp zoea can handle much bigger pieces than same size fish larvae,because they donÃ"šÃ‚´t swallow their prey but grab it and chew it.You can actually see them holding a bbs with their legs.

Awe man now I am going to have to try to breed something else... I wish you luck as you progress Lisa and make sure to keep us updated!!!!

 

[LisaP]

OK, I feel really bad now. I've been starving the poor things.

I started off a culture of bbs first thing this morning and another 5 hours later so that I can feed them newly hatched nauplii first thing tomorrow morning and in the afternoon too. How many should I add per ml and what should I do about the bbs that remain uneaten in the tank after 6hrs??

Many thanks for all the comments so far.

Regards

Lisa

Just another thought. Would it be worthwhile adding some copepods now? There aren't enough to harvest from my independent culture but it would be easy enough to siphon some out from the refugium of my big tank. They are a species of pelagic copepod, would they be too big for the zoea to tackle at this stage?

I wouldnÃ"šÃ‚´t mess with anything else than bs,but itÃ"šÃ‚´s just MO.I donÃ"šÃ‚´t know about Thor and it seems nobody does here (perhaps Purplehaze?),so,youÃ"šÃ‚´re very much on your own.Good luck and keep posted

I'm just taggin along, breeding sexys has always been a dream of mine so hopefully you do it so you can help the rest of us! I wish you the best, btw awesome photo's

A quick update: The shrimp are 6 days old and look like this...

It's not a great picture I'm afraid but the lil thing just didn't want to move away from the side of the petri dish and since I don't have that many to play I didn't want to kill it just for the sake of a picture.

Sooooo, are they at the second stage?

Right,Z2,though the eye stalks are short like the antennae.
You now must check the telson for the appearance of tail fins.Also try to count walking and swimming legs.
I understood at last how you adapt your camera(fast,uh?).You can not remove the lens but there is a thread where you can adjust an additional inverted lens.Did I get it?

LisaP congrats on the shrimp thougth i let you know great work

 

[LisaP]

Yay! Z2, now how many more are there to go? :lol:

Luis, that's right! I simply attach the extra lens via a reversing ring.

Lisa,

The larvae stay on the bottom for the first couple of days, then start to "swim" in the water column. Start feeding BBS from day1.
You can feed once a day, if necessary twice. Feed enough so that each larvae doesn't have to spend to much energy getting to the food. If the bottom gets to dirty siphon it out.
Photoperiod of 12-14 day, just enough light for you to see both the larvae and BBS.
Temp: 26-28 C, salinity at 33ppt.
You can use a 5-10 gal tank. Cover all the sides.
You should get your first pos-larvae in 22-29 days.
HTH
Good lcuk

:thumbsup:

Great! Thanks Purplehaze.

Just one other query. What do you all do with the older brineshrimp in the larval rearing tank? I can quite clearly see the difference between the newly hatched shrimp and those that are 24 - 48hrs old now. Are they OK to leave in there or should I make a serious effort in trying to remove them??

I'll keep you all posted of any progress.

Regards

Lisa

Would it be a good idea to add phytoplankton to the tank water as we do with clowns to keep the brine fortified?

Well, if too many are left then you can siphon them out every other day! Just put a micron screen before the airline tube, that way only the brineshrimp are flushed out of the sistem and not the larvae.

No,it wouldnÃ"šÃ‚´t.In very few days the bs would outgrow the shrimp!

Starved bs molt to the 2nd.stage,instar 2 and then die and must be siphoned out,unless they can be removed with appropriate screens before they die.

This is a general problem of larval husbandry,what to do with uneaten live food,and aquarists use their ingenuity to find ways to deal with it.

Hallo Lisa

Viele Grüsse aus Deutschland.
Ich züchte die Thor seit Dezember 2004 nach.

Ein kleinen Bericht findest du auf

http://www.nachzuchtenregister.de/Garnelen_Krebse/garnelen_krebse.htm

Leider ist mein Englisch so schlecht das ich nicht aktiv am Thema
teilnehmen kann.

Aber purplehaze ist ein guter Freund von mir und wird es dir sicher übersetzen.

Viel Glück

MfG Sylvio

Hallo Sylvio,

Vielen dank für der information. Es ist extrem nützlich.

Ausgezeichnete Web site.

Willkommen zu ReefCentral.

Mit freundliche grüßen

Lisa

I hope that's understandable, my German is extremely rusty.

 

[Sylvio]

Hallo Lisa

Dein Deutsch ist gut.

Züchtest du noch andere Tiere?

MfG Sylvio

 

[LisaP]

Hallo,

Ich versuche auch, den Goby, Gobiosoma multifasciatum, anzuheben.

Lisa, ja jetzt weisst du wen du fragen musst
