I know it's easy enough to force reproduction in various anemones by simply cutting them in half (Anthony, I saw your IMAC workshops this year where you split a couple anemones, and have heard rumors that you will be giving a fragging workshop at our local reef club next month- Im looking forward to it!). But, has anyone had any success with sexual reproduction of anemones in captivity? Ive seen some work done with Pocillopora and a couple Favia sp, but cant really find any good info on anemone-centered efforts. Any suggestions about where I might find some good info on whatever work has been done??

| cheers, my friend... very good question. There have been observations of the release of gametes more than a few times (understatement). I suspect these were mostly a release of sperm. Decent activity as I recall has been observed in the Carpet anemone varieties and Dr. Shimek has addressed this before too (identifying reproductive structures to look out for in candidates for spawning). I must admit though that I cannot recall hearing of a successful settlement from sexual reproduction in aquaria. I will note this thread in the archives (anemone links and spawning reports) with hope in time that folks will add more to it. Looking forward to it! Anth-

I appreciate the response. Yeah, I had heard of spawning events in tanks, but like you said, nothing as far as successful settlement for anemones. Does anyone know of any research currently concentrated on the captive rearing of actinarians (as advanced or undeveloped as the field may be, I really havent a clue)?

| now that I can help you with, my friend... and I see that you are new to this forum. Let me introduce you to my default mega-source for information: atop this forum is a sticky called "Fav links..." and in it is a years old collection and growing of my favorite reosurces. URLS, books, articles, threads and discussions. in it you will see a link (reminder really) for folks to use Scholar Google. If you tag that link and enter "actiniaria reproduction" for example... you will see several hundred hits on the subjecvt from the science and academic archives (albeit field work). Please do make use of that list of "Fav links..." (especially scroll down to the alphabetical list of discussions for current events)

Anthony,
Waikiki has successfully settled spawns of E. Quadracolor. I believe there are photos in on of the TRA volumes. I don't know if they have reared them, although it doesn't seem like it would be that hard.

do you recall is these were the products of sexual reproduction or asexual (planulation). I was thinking the latter.

| Anthony, I am almost certain they were sexual spawns. I will find the reference and report for sure. Adam

| See the captions to images on pgs 112 & 115 of The Reef Aquarium vol. 2 (Sprung & Delbeek). Summary: "Entacmaea quadricolor larvae collected after an aquarium spawning event at the Waikiki Aquarium.... planulae develop within 24 hours after fertilization, and settle out on a variety of substrata." (p115) "The zooxanthellae are clearly visible inside this young Entacmaea quadricolor that was spawned and reared in captivity." (p112) [My emphasis] - Mark
