Environmental Factors Affecting Corals and Coral Reefs. Environmental Factors Correlated with Healthy Reef Coral Growth. Warm tropical water Normal seawater salinity Appropriate solar radiation Low organic nutrients (oligotrophic) Low turbidity Low sedimentation Vigorous water motion.

with Healthy Reef Coral Growth
Only green and blue wavelengths pass through water a great distance.
(i.e., visible light)
The rate of production of organic matter by autotrophs
6H2O + 6CO2 + light C6H12O6 + 6O2
Blue-green algae (cyanobacteria)
C6H12O6 + 6O2 6H2O + 6CO2 + energy

Measure Actual Rates of Primary Productivity
Table 1. Average net primary production and biomass of aquatic habitats. Data from R.H. Whittaker and G.E. Likens, Human Ecol. 1: 357-369 (1973).
Gross Primary Productivity (GP)
Net Primary Productivity (NP)
NP = GP + R
Note that R is a negative value because it results in the reduction of organic matter.
Avoidance ability- this is a function of reactive distance, radius of net, speed of tow, burst of speed of larvae
To reduce net clogging:
Light & Dark Experiments
light + 6CO2 + 6H2O C6H12O6 + 6O2
C6H12O6 + 6O2
6CO2 + H2O + ATP
