AEFW experiments and study

I wouldn't be surprised if your fresh box of matriculated pieces came with a new batch of AEFW

Yup. I used to buy lots of mari pieces before. More than half the time I used to find AEFW's.

The crazy thing is...there were never any bitemarks on the maricultured stuff.
 
would be interesting to experiment with different trace elements dosed int he container ... see how they react to it. u might find an in tank treatment to " shock" then and kick them off Acros,
 
I too would be curious of the following if you haven't dumped your experiments down the drain yet

1. How long till eggs hatch (you mentioned 3 weeks as a source, but is that for your breed of aefw also?)
2. How long will newborns live without food, ie, how long after they hatch till dead with no food source.

As the eggs I have in the containers were laid over a weeklong period, I'm going to start over to find out how long they take to hatch. The 21 day period was what Dr. Rawlinson observed for her 2009 experiments. I need to find out if my AEFW are similar. The newborns living without food will probably need to wait until we can get enough funding for Dr. Rawlinson to come to my place, as they are so small when they hatch.

LOL, I was hoping they would! No such luck...
 
This is such great information!!
Thanks again for doing this time consuming research.
It makes me cringe a little when I hear all of those names of acropora that are so nice but are slowly being sucked to death by flatworms.
I know they are maricultured and therefor not really affecting the environment, not to mention the fact that these experiments will hopefully save more acros than will be lost, but it feels weird... We've spent so much time and effort keeping our acros free of pests, it feels odd to intentionally infect them..
But... I'm on board here! And I support this research..
Keep up the great work and thank you..
 
I'd be curious to know about temperature and how it affects flatworms..
I've heard that low temps- 74 or so and a little lower may really slow down reproduction and longevity..
 
Long time no post :)

Been working a lot on getting my dedicated AEFW system up and running. Had to build and paint a couple aquarium stands, clean a lot of old used equipment, wire up some new plugs to a dedicated circuit, program the Apex, plumb everything together, make frag racks, etc. Plus as part of the system has MH and a fan across the top of the tank, I had to do what I've been putting off in the fishroom for a few years, get a dehumidifier and install an exhaust vent - major PITA, with having to put a hole in the house wall, install a variable speed controller, put in the vent/box in the ceiling, and work in the crawlspace between floors (in a 12” x 14” opening in the trusses) to install the outside cap, hang the inline fan, run and tape duct, and run a bunch of wires back and forth to hook the fan up to an open circuit and the speed controller. So...hopefully that explains my temporary absence on this thread :)

Now the system is up and running! Moved a bunch of frags over from my main tank this past week, fragged out some of the colonies I bought, and am slowly moving them over too. Some are so nice its very hard to do that, one's coloring up to an awesome light blue...This next week I will be deliberately infesting each frag with some adult AEFW...I feel like I'm committing some sort of cardinal reef sin LOL!

Once my AEFW colony is going strong, laying eggs, I will have more than enough young and adult AEFW and eggs to perform many more of the experiments on my list. Hopefully if we can get our funding in time Dr. Kate Rawlinson and I will also be able to delve much deeper into the scientific side of the AEFW than I will be able to do on my own.

I will update this thread with new information as soon as I begin running new experiments. Stay tuned!
 
wow indeed!!!
that's dedication..
thanks for doing all of this, it will be greatly appreciated by many people!
 
Not yet...I want to study their lifecycle before methods of killing, with a finite supply of them at the moment. I need to get my hands on some cheap ugly acros to up my supply of food for them, then I'll have extra to experiment with killing directly.

Awesome keep us posted.....:bounce3:
 
Stand building, I recommend NOT doing this in your living room...






Full system together. Consists of a 57 illuminata with the stand I just built for it, 75g sump, several 20 gallons (not currently running, for future experiments), chiller, dual 250w MH + T5 supplement fixture, JBJ ATO, Apex controller with 2 EB8's, mag 12 running both the return and chiller, K3 for the sump and WP40 for the 57 tank:


Sump area, chiller under the 57:


One of the 20 gallons to be used later, the tank behind the 57 is a 20 gallon ATO reservoir:


I was going to put another 20 gallon tank up above here, but it turned out to be a better place for equipment like an EB8, the MH ballasts, ATO controller, WP40 controller, temp control fans:


Apex under the 57, with the second EB8. Power cords held in place with electrical conduit holders:
 
57 illuminata with dual 250w MH, 4 36w T5 bulbs, and LED moonlights:


Some frags moved over (yes, some non-SPS for the moment...)


Frag racks I made for the tank, most holes are 1/2" but drilled some 3/4" for the square or larger bore frag plugs:




In tank before the old MH bulbs grew some diatoms:




Some of the colonies for the AEFW system:









 
Just because I wanted to play with the viewer I just built specifically for my macro lens + top down pics :)















 
Looks outstanding, so what's the goal here ? Are you experimenting with what will kill them and if so what are you planing to start trying? Will it be an in tank treat ment or a dip treatment? I think you have pretty much found out how long they live without a host and the life cycle of the eggs hatching but what treatments have you tried to eradicate them?
