Coral Reef Growth Corals have specific requirements for growth Require correct Light Temperature Salinity Sediment type Are very sensitive to pollution Light and Temperature Need enough light for zooxanthellae t
Cnidarians are the life forms that secrete protective substances that make up the solid base of the coral reef They are polyps, so they are stationary They like between 23 and 29 degrees celcius, 32 to 42 parts salinity, and clear water so that sunliight can penetrate at least 70 meters ...

The average salinity is 40 parts per thousand (ppt), as compared to about 35-36 (ppt) in the tropical Indian, Pacific, and Atlantic Oceans. Recent measurements found surface water temperatures to be 28 degrees C. (82 degrees F.) in winter and up to 34 degrees C. (93 degrees F.) in...

(Seattle Corals Aquariums) and was raised in a 11.36 L aquarium with specific density = 1.024 g/cm3and pH = 8.4. Artificial seawater was made from Instant Ocean Reef Crystals Reef Salt with the salinity = 34.1 ppt. A one third water change was carried out every 3 days to ...
Colonies of Stylophora pistillata were exposed to five salinity concentrations [39parts per thousand (ppt), 32ppt, 28ppt, 24ppt, and 20ppt] that may realistically occur on a reef. Histological examination indicated an increasing severity of pathomorphologies associated with decreasing salinity, ...
Factors that affect growth rate: Overfishing of herbivorous fishes Ocean temperature Salinity Low inorganic nutrients Solar radiation/Water transparency Sedimentation Can you think of any others? Reef Erosion Predation—Herbivores feeding directly on the coral or the zooxanthellae Bioerosion—Predation (above...
Coral reefs are a delicate ecosystems that require a balance between many factors and can easily become threatened. Sediment accumulation Environmental Changes Temperature pH Salinity Eutrophication Costal Development Overfishing Removal of top predators Pollution Visitor Overuse Diver Damage ...
