basser1 Posted October 16, 2009 Share Posted October 16, 2009 Hey gang! Check this out! http://www.reefcentral.com/forums/showthread.php?t=1723196 There have been instances where folks have said there clams spawned in their tanks. But this guy has a pic of his deresa that actually produced a baby. And incredibly, it looks like the tank was not taken care of for quite some time while they were moving!! So while we're all concerned about pristine water conditions, maybe we need them to get a little dirty? Thought I'd post the pic here in case you can't see it from the link: Link to comment
fiction101 Posted October 16, 2009 Share Posted October 16, 2009 I've always read that clams need a lot of nutrients so that makes sense. Link to comment
Jacobnano Posted October 16, 2009 Share Posted October 16, 2009 You should post the pics on here, I am not a member so I cannot view them. Edit: Nvm all good Link to comment

ls7corvete Posted October 16, 2009 Share Posted October 16, 2009 How do we know the clam as simply just to small to notice prior to now? Link to comment
Marteen Posted October 27, 2009 Share Posted October 27, 2009 It could be the crappy water conditions stressed the clam into spawning. That makes more sense than dirty water was soooo good for the clam it decided to spawn. Link to comment
Urchinhead Posted October 27, 2009 Share Posted October 27, 2009 Actually clams like a bit of nitrate and phosphate in the water. They use fertilizer in clam farms to promote growth and spawning. Link to comment

Sure they like a little but from the RC post it sounded like he hadn't changed the water or payed attention besides top off to the tank in 6 months. With trace minerals probably depleted and calcium and mag levels low I'd imagine the clams would be pretty stressed and spawning to hope their genes can escape the declining health of the local water.

TJ_Burton Posted October 27, 2009 Share Posted October 27, 2009 I am skeptical. There isn't enough proof documented to say definitively that this smaller clam is in fact the offspring of the larger clam. I wouldn't consider this to be "The first documented reproduction of a clam in an close system". Although it is technically possible for a single spawning derasa to reproduce in a closed system, it is pretty far from probable. I think if someone is going to claim this sort of event has occurred, they better have some good evidence to prove their theory correct. Link to comment
johnmaloney Posted October 27, 2009 Share Posted October 27, 2009 they breed clams all the time though don't they? Link to comment
TJ_Burton Posted October 27, 2009 Share Posted October 27, 2009 they breed clams all the time though don't they? Not in small closed systems like aquariums! Most of the time they are pumping ocean water through their large vats. If you ever see pictures of clam breeding facilities overseas, they are pretty large scale and outdoors. Link to comment

johnmaloney Posted October 27, 2009 Share Posted October 27, 2009 oh okay I get it...I thought it was about breeding them rather than how they were bred....carry on then! Link to comment

I read that too. Regardless I felt it was a good idea to mention that these clams are actually capable of breeding on their own. More or less to say that just because he has two derasas, doesn't mean they created offspring using both of their genetic material. If you can imagine both clams releasing sperm and eggs into the water column, there is just as much of a chance (if the spawning was at all successful) that the young clam is a product of the genetic material from the same clam.

OIC. well thats a good tidbit of info you provided. i for one did not know clams could self replicate. Link to comment
RyanR1212 Posted October 27, 2009 Share Posted October 27, 2009 at my school we have been trying to spawn clams.... we have gotten them to the spawn sperm and eggs but we cant get the baby clams to live over 24 hours.. so we are still working on it hopefully for sucess soon!!! Link to comment

Good point to mention! I do not doubt that the clams are able to successfully spawn and produce viable fertilized eggs it's a matter of the planktonic stages surviving in our tanks. We have a ridiculous amount of obstacles in our aquariums that would destroy small floating "baby clams" like power heads, skimmers, overflows, returns, fish, corals, etc. Even when people are trying to breed clams in a university environment after tons of research, preparation, and special care, it still proves to be incredibly difficult. That is why I am so skeptical. Link to comment

basser1 Posted October 27, 2009 Author Share Posted October 27, 2009 Hey glenn.... I saw your thread. Do you still have the clam, any updates, pics, etc.? I just realized I am actually capable of being a real prick on RC. I can't help it... LOL!! TJ I just saw yor posts over "there"! Don't let 'em get to you! Link to comment
TJ_Burton Posted October 27, 2009 Share Posted October 27, 2009 LOL!! TJ I just saw yor posts over "there"! Don't let 'em get to you! Did you see it before I edited my last line out? hahaha... Oh dear... Link to comment
