Additional Information
Miscellaneous Information:

Well its been awhile.
I haven't done any shrimp or fish breeding for about 8 months now due to ill health but thankfully things seem to be improving. So much so that I've finally started getting the larval system back up & running.

First off I'm throwing on a batch of Lysmata Debelius (Blood Shrimp), I have had success with these guys before, successfully getting 2 settled shrimp after approx 3 months (one died after 4-5 dies, the other I beelive has been eaten along with all my peppermint shrimp in my display tank, anyone know how to get rid of a Mantis without pulling a tank down?)

I'll add some pics of the hatch from last night a bit later (I had a few spare minutes & thought I'de have a read up of whats happening)


I'll also start a log up for the Lysmata Amboiensis (Red Line Cleaner Shrimp) after they present me with a batch of larvae.

Here are the pics of the larvae, these are approx 12 hours olds, I've poured them out of the larval snagger into a container so I can acclimate them to the larval system water.
The Larval snagger is left in the parents tank overnight & all day as I don't have time in the morning to acclimate them to the larval system.

This batch I've seperated into the 2 different tanks.

Ok, time to jynx myself!

Things appear to be going much much better than the last few batches I treid of these guys 6-9 months ago, these ones are actually still alive! I'm guessing that would most likely have to do with me finding and removing a rusted hose clamp (so much for 316 stainless, turns out the bolt wasn't !@#$%&)

No pics of larvae as I'm having issues with my scope being recognized by the PC :(

Time to jinks myself.

The larvae are doing really well there are quite a lot that are at Z4 and almost zero die off (maybe 3%) which is more than I can say for the l.ambioensis larvae.

Jackson,

Yes they are both connected to the same system but in different tanks.

Still lots of larvae left, I haven't seperated them out to reduce their number in each brt as yet.

The numbers have reduced but there are still way too many to count, I'll try and get some pics this weekend.

OK, these guys are 3 weeks old today (YAY.... only 49 or so more days to go)

I'm having an issue with my nhbbs currently, I'm seeming not able to 'boil' them as well as I used to even though I'm using the same container & stone, suffice to say the cysts find there way to teh bottom of teh container and don't hatch :( have thrown together an upside down 'pop' bottle to see if that improves things.

Its going to be 35 days as of Sunday and I have more than 80 larvae left, still some are early stage eg. Z5-6 but there are quite a few that are well past that.

At least they have made it to the half way mark *crosses fingers*

I also had another hatch last night.

35 Days and we have pics :D

The first image is 21.5mm in width

The reamining images are 2.8mm in width

What I find VERY interesting is the differences in development compared to Luis' excellent images of teh various stages of larval development http://www.marinebreeder.org/phpbb/viewtopic.php?f=201&t=1215&start=0#p9749 my images above are showing more development in the pleopods considering both my larvae & Luis' are teh same age!

EDIT: Correct link

The 6 week mark.... well... 6 week +1 day ;)

Still have LOTS of larve left, maybe lost about another 4-5 larvae that I can tell, there are still way to many to count.

I'll try & get teh largest larvae out sometime this week & get it under teh scope to see what teh development is like.

I don't think I relaised just how many larvae were still left!

I was in teh fish room after lights out last night gathering some orchid dottyback larvae and while I was waiting for the larvae to acclimate to the larval system I had a look at the L.debelius BRT's, there are HEAPS or large larvae, I'm pretty sure I have miscounted and there could be twice as many as may original count or 80 odd larvae, I also noticed some more dead larvae & I'm goign to thin the larvae out some more on teh weekend as they are tripping over each other!

Sorry no pics as it was dark lol

Ivr also noticed significant breakout of hybrids in 3 of my brts which is & has taken its toll on 2 brts worth of early stage larvae and a significant chunk of late stage larvae.

Does anyone know if hydroids are dependant on light? the reason I ask is that 2 brts wither the same batch of larvae, 1 has been decimated over night the other appears to have no hybrids. they are on the same system, same water, same food, the only difference is one is directly under the light the other is only half under.

TIA

I cleaned out 2 of the BRT's today. L.ambioensis (which had no larvae & a mass outbreak of hydroids) :( & one of the L.debelius which still had 40 larvae left (was 43 but 3 where in their death throws).

This is after an hour of fishing them out of there BRT..... and for teh record its not a simple task when they are this size in a BLACK container)
Image

Here are some pics of the largest larvae I could find

Image

Image

Image

Hopefully not long now, tomorrow they will be 42 days old

The second BRT of L.Debelius only has a minor outbreak of hydroids and I'm not too concerned with that as yet but will clean tehm out in teh next day or so.... there are apporx double the amount of larve in teh remaining BRT :shock:

Tomorrow It will be 8 weeks since this batch was released by the adult and I have more than 40 larvae remaining.

I had a couple of outbreaks of hydroids in both teh tubs I have these guys in which took its toll but for the most part I'm not loosing many since then.

This is one of the largest larvae that I have (the image is 2.2cm wide)
Image

And here is a close up of the pleopods (both images were taken a few days ago so its certainly possible they could have molted and developed further)
Image


By my eye they are in teh second last stage, 2 more mlts and fingures crossed I'll have a number of juvenile blood shrimp

That really depends on how many actually do settle and how long they take to grow to a saleable size.

depending on numbers several will be donated to my local Aqaurium club for 'fund raisers' teh rest will probab;y be sold of to local LFS's

An Update!

The larvae are 66 days old today!

I have approx 40 left, they are looking really good providing a mow down the hydroids every couple of days.

I'll pull a couple of larvae out on teh weekend to scope & shotglass.

Emptied the BRT out today to give it a scrub and some relief from hydroids, while I had them out I did a count & I do have 41 late stage larvae left, 2 of which appeared bigger than all others.

Here are some shot glassed pics of the largest larvae..

And some slightly closer images...
