Phylum Cnidaria Colonial growth Foundation species
4
Commercial Conservation Research
5
Sold as ornamental organisms for aquariums Prices vary based upon coral species, color pattern, and colony size ◦ More colorful is more expensive Corals are cultured and sold around the world ◦ US is main purchaser High shipping costs
6
Zooxanthellae symbiosis Calcium carbonate skeleton Reef builders
7
Flexible Lacy appearance Proteinaceous skeletons
8
Stony corals – Order Scleractinia ◦ Family Acroporidae -SPS Montipora spp. ◦ Family Dendrophylliidae - LPS Turbinaria peltata Dendrophyllia fistula Soft corals – Order Alcyonacea ◦ Family Alcyoniidae Sarcophyton spp. Sinularia spp.
9
Montipora spp. Purple Montipora capricornis Supernatural Montipora capricornis
10
Turbinaria peltata Green Pagoda Coral Dendrophyllia fistula Red Sun Coral
11
Sarcophyton spp. Green Toadstool Leather Long Polyping Leather
12
Sinularia spp. Blue Devils Finger Leather Yellow Fiji Finger Leather
13
AsexualSexual Budding ◦ Colonial growth Fragmentation ◦ Colony physically broken into separate sections Spawning ◦ Free swimming larvae ◦ Adult sessile polyps ◦ Hermaphroditic and non-hermaphroditic types
16
Asexual growth “fragging” Development from zygotes ◦ “spat stocking”
17
Indoor tanks – Intensive ◦ RAS filtration system ◦ Zooxanthellae very sensitive Floating nurseries – Extensive to Semi-intensive ◦ Shallow water ◦ Reef building
18
Tropical waters ◦ Bright light ◦ Temperature: 78°F to 84°F ◦ Salinity : 1.026 s.g. ◦ Calcium: 390 to 450 ppm ◦ pH: 7.9 to 8.3 ◦ Alkalinity: 140 to 180 ppm
21
Zooxanthellae provide energy Dissolved organic matter Plankton and small organisms
22
Fast growing Minimum feeding Easy to aquaculture Conservation efforts
23
Harmful to humans Expensive Predation and disease
