SRC Member angelfishlover Posted October 22, 2008 SRC Member Share Posted October 22, 2008 I would like to know wethger bleached corals in the wild will heal or not?Cause i have been debating with non reef keepers that those bleached ones can survive. Let's face it.The corals we are taking care of have been through the ice gae,more global warming and others.If we gave them time in the wild without reducing the fishes,the corals may survive.From what i know seawater around the reefs contained more plankton than our tank does which we drip in rotifers Anyone can show me the pic of bleached corals that you have saved will be greatly appreciated so that i could actually prove to those who don't dive into the reefing scene that corals may survive with sufficient food.Uhh i have a gonio which is bleached but now it gets back it's zooxanthellae already.

SRC Member vt_snowman87 Posted October 22, 2008 SRC Member Share Posted October 22, 2008 may i know what's bleached corals? it means corals that expel their zooxantellae (symbiotic algae) such that they seem white (void of colours), due to stress, temp, amongst other reasons.. just nice i happen to be doing a project on reef conservation in southeast asia now.. through my research, bleaching is actually the corals' way of surviving.. because it hopes to be able to host better algae that can generate food for the corals despite the "change".. because in times of stress, sedimentation, the zooxantellae that is hosted within is unable to generate food for the coral.. an interesting article to read would be the El Nino mass coral bleaching in the 90s.. therefore, my view based on coincidental research, corals (including SPS) do get better and heal themselves in the wild even after bleaching given conditions improve, and coral is able to host back the algae.. however, with humans' increased coastal activities, illegal blast fishing, sedimentation, and global warming, researches have shown that the percentage of bleached corals healing back to health is declining rapidly in today's reef.. just my 2 cents..

I totally agree with you.Over fishing=less fish poo=less phytoplankton=less zooplankton=Bleached corals can't survive=End of coral reefs.Is a chain reaction.

SRC Member LaW Posted October 22, 2008 SRC Member Share Posted October 22, 2008 bleached reef will recover, provided the necessary improvement but might not be 100%. global warming is the primary cause and overfishing being the one of the least secondary. the next big thing is water pollution. if you are talking about less poo, take at look at the sewage to the sea, it contain more nutrients that keep phyptoplankton, algae and red slime cyno extremely happy. of course, not all reef are experience the pollution directly, but water and water are side by side. In short, temperature plays a biggest role in the reef, if the water is too warm, zooxanthellae being expelled, coral bleached and stony corals got problem building their skeleton. they need a specific certain temperature to do so. too warm? nono Quote If a man could beat his own fantasy. Then to only breed in captivity. Then its pointless. Genesis 1:20 And God said, Let the waters bring forth abundantly the moving creature that has life, and fowl that may fly above the earth in the open firmament of heaven. And God created great whales, and every living creature that moves, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that it was good. And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth. And the evening and the morning were the fifth day. || Tank: 78" x 30" x 30" || Sump: 48" x 22" x 20" || Lights: PowerModule 10 X 80W|| Returns: 2 x HF32 || || Skimmer: BubbleKing Supermarin 300 || Wavemaker: 3 x 6100 & 1 x 6200, 2 x Wavebox 6212, WavySea || || FR: 2 x FR150 || NR: Sulphur Denitrator || CR: RM Custom Made 8" || KR: Deltec KM500 || TopUp: Tunze Osmolator 3155 || || UV: Coralife 12X 36W || Ozonizer: Sanders C200|| Controller: GHL Profilux Plus II Ex || Link to comment Share on other sites More sharing options...

Corals is like having loads of dangers now.We shall try saving it.And try not to get anymore Harlequin shrimps as they also contribute in reducing crown of thorns numbers.And cut that carbon usage(use efficient energy saving reef equips).Or the corals suffer like what they did in Ice Age.

SRC Member vt_snowman87 Posted October 23, 2008 SRC Member Share Posted October 23, 2008 Many fishermen in the coastal areas are practising dynamite fishing (blast fishing), what happens is they use explosives to bomb an area of the reef, therefore all the fishes will just float to the surface and they are able to earn much more profits as compared to conventional fishing or fish farms.. the downside being, alot of the precious reefs are also bombed away in the process.. this applies more towards southeast asia waters.. i do agree global warming is a worldwide cause of reef health degrading, as temp increase not only causes stress to corals, when ice caps melts, there are increased water level and sedimentation, causing sunlight to be unable to pass through, and causing corals to expel their zooxantellae as well.. in my opinion, increased management, and supporting aquacultured/propagation, and increasing education to the public regarding issues on our reefs is the way to go..
