Acropora spawn!

Very fantastic read so far. Have you guys ever tried to collect the spawn?

Oh you betcha. We had a successful spawn last year that resulted in over 120000 fertilized embryos.
I believe the long island aquarium uses a fine net certain times throughout the year.
That is generally for fish eggs/larvae. Most spawning coral's gametes float, so you just scoop them up and ivf them.

I've always read the aquarium socialized articles on coral reproduction, find it very fascinating. Although most things you can't put a finger on, I found eggs just like how I photoed up against the glass - the night after the eclipse. There's so much more involved with what goes on, that I'm having trouble understanding this topic.

It's all groundbreaking stuff, really kicked off by Jamie Craggs, who is still pushing the boundaries of what we know and how to do it. It is very involved work, but read some stuff and see if it makes sense. What you really need is different genotypes of coral because they don't really self fertilize.

Here is a video from our spawn last year:
And here is a video that Neptune Systems made where we talk about a lot of stuff regarding what and how we are doing. I think it might say stuff in an understandable way:

Such a brilliant video, both of them are near unbelievable. Its truly a fundamental part of knowledge to keep our oceans thriving. Can't even imagine how exciting your job must be!
In the Neptune apex video, CAS has started this program December 2016? Have you guys grown out any pieces into thriving colony's yet? Any other fun things on your agenda? Thank you for sharing the videos and being here to talk about this is really neat stuff.

I haven't read much on genotypes with coral just yet. That will be interesting read.

Heres some photos from the week prior. This was the "pink cadillac" acropora, not sure of its species. Had found eggs tumbling around the water surface inside my filter socks. That same night i had made a fragment from this piece and found these eggs inside. This was the first time something ever happened like this, so it took a while to put 2 and 2 together.

The first piece i posted, i have 2 other smaller colonys that were releasing eggs that night also.
 
Here's the eggs I found in a staghorn Acropora growing in our 10000L tank. When comparing to Jaime Craggs pictures I think these are ready to go any day. Or maybe they're parasites, I can't say for sure :D

Unfortunately we didn't see the actual spawning event. We're a small Aquarium but I hope we will able to do some controlled spawning experiments soon. We've got some large colonies to try with.
 
Can you tell me about the lighting cycles in the tank? This is smack in the middle between full moons.

We have some brooders corals from last year developing. Due to various reasons, mainly the marathon of system build, collection, spawning, and IVF, we were really tired by the last 10 feet of the race, and had some issues in the week after settlement. The pilot effort was still a huge success are we are excited about the next couple of months.

I run an ati dimmable t5 florescent 6 bulb fixture, along with a reef brite tech actinic led strip.

Don't have a moon light cycle, reefbrite kicks on at 9:45 AM, shuts off at 9:45 PM. 2 of my t5 bulbs turn on at 11. The other 4 kick on at 12:30pm to 6 o'clock then the other 2 bulbs stay on until 8 o'clock. Reefbrite turns off at 945 PM. Just to add, the clock on my fixture is quicker then normal time. 30 days usually will result in a 8 minute time loss compared to real time. So every month or I'll need to adjust the clock back to real time. Other then the occasional flashlight, or turned on lamp, that's the only anomaly.

That's well surpassed an astounding accomplishment, you guys rock. Can't wait for the next round of footage.
 
Hello! Very intrigued as for last night, I had my acropora spawn and almost overfill my filter socks for the second time in basically a week. Documented it on my build thread. Found some eggs floating around during the eclipse we had recently. Did my fair share of fragging the last few days and am finding egg sacks inside my acros. Took a quick peek last night, and found hundreds of orange blobs piled up against the glass on the water surface. Also flying out of my large wwc yellow tip colony just like I've seen on the acropora spawn videos. Very proud of this. This hobby continues to peak my interest after 7 total years of having aquariums. Has anyone experienced this? Would be a great topic to discuss. I have a cup, water surface filled with eggs that now settled today. Don't know what I'm doing, but would be really neat to try giving them a shot at growing

Following to see what comes out of the eggs

I was going to say - @Thales is the person you want to talk to but he showed up :) . Also those videos are great. I have watched the apex one now a couple times just because it seems natural. By natural I mean not OCD or so clean you can eat off the floor. It sort of seems like something I'd have set up in my garage sort of thing.
 
Yes I do.
@Sabellafella

It is my understanding that moon cycles play a significant part in coral spawning, I'm curious do you have any windows near the tank? I know you said no moon cycle.

I'll try my best to get into more detail about what exactly happened.

Yes, 2 pretty large windows in the same room my tank resides. My tank doesn't receive direct sunlight from them, just ambient.

During the blood moon I believe was toward the end of January, I had cut some frags from a few acropora. Just two species had egg sacks inside of them. The egg sacks were off white. When I put my pink Cadillac colony into a container, there were only about 2 or 3 white blobs sticking out of the polyps. My hermit crabs spawn every single night for about 2 years straight now. Anytime at night I can go up to my tank with a flashlight, and see tons of what appears to be mysis shrimp(they are actually hermit crab babys) jolting around in the water column. I've seen and photoed acro polyps eating them before, so I just assumed the acros were pooping that night, when in reality those blobs clogged my filter socks up LOL. Fast forward about a week later, checked my tank at night again with a flashlight, and actually seen the yellow tip acro rejecting the orange blobs very very quickly. Same with the pink Cadillac.I would think they would be small, but the eggs are very large. So when you have tons of them flying around your tank it's very noticable as to what had happened. Alot of them just migrated up against the water surface and panes of glass. There was already some lps corals all puffed up from eating them, so I most likely made it late to the party.

The ones I collected in the cup, they settled out, and never grew. They probably just died right after settling. What amazes me, the pink Cadillac was just a frag a little over a year ago. The yellow tips is atleast over 2 years old. So the real question for me is, when does sexual maturity start for these little guys?
