原帖是 RR论坛上有位朋友做了个AEFW的生存实验 *还非常强大的开了众筹。。。。最终筹到了6000+刀

Summary of Experiment 1, observations and results:
AEFW are nocturnal.
AEFW are capable of laying a lot of eggs, even laying them up to 9 days with no food. In the 3 compartments that had consistent egg laying (compartments 1, 2, and 3), egg laying remained fairly constant through day 7. The number of eggs per cluster decreased over that time period, but not the number of egg clusters.
As one cluster of eggs was laid in the 2-4mm compartment, AEFW may reach sexual maturity pretty quickly.
The coloration of the AEFW quickly faded from their normal mottled brown color to white, as the experiment progressed. Their size also shrunk considerably, ending at about half their original size, with a third to a quarter of their original body mass (rough visual estimate only).
As far as size vs. life expectancy, the majority of the 1-4mm size died on days 9-10, the 4-10mm on days 12-13, the 8-12mm on days 14-15. The largest ones lived about 30% longer than the smallest ones.
Conclusions that I am NOT drawing from this experiment:
AEFW will die in ~2 weeks with no food.
This was just the first run of this experiment. I want to run multiple identical experiments to compare results. I am also trying to get AEFW from other sources, to compare the results of my population to others, to find out what variation of results occurs in different populations of AEFW.
Side experiment I thought of: find out when the point of no return is. As the AEFW decline in health, is there a marked point before death that they are not able to recover even when put back on Acropora?
And because I like charts AEFW populations and egg-laying graphed by day
As I desperately needed some more acros to keep a steady supply of AEFW without killing their hosts in order to continue these experiments, I bought a box of maricultured colonies. My own tiny collection of acros are about ready to die after months of predation, they desperately need a break. The new colonies are all different species. Acropora abrotanoides, caroliniana, divaricata, delsawii, formosa, millepora, hoeksemai, horrida, humilis, hyacinthus, loripes, papillare, parilis, plana, robusta, suharsonoi, tenuis, turaki, valida, and yongei. My AEFW will be in heaven! The corals look so nice it is really hard for me to deliberately infest them
HUGE thanks to Brian at my LFS 3rd Coast Corals for ordering them for me and driving TWICE to the airport to pick them up, due to errors on the airport's side, at 11pm and 4am! And then delivering them to me, an hour's drive away, at 5am in the morning.
Blablablaaaa~~~
{:2_43:} Interesting update: Preliminary study indicates that AEFW juveniles die within 24 hours of hatching with no access to food. |
