Nutrient Loading
Coral reefs thrive in nutrient poor water. Excess nutrients from runoff, wastewater treatment plants, coastal development, marinas, etc. can encourage the growth of fast-growing macroalgae, which can smother a reef.
A new study has shown that reefs overgrown with algae or characterized by coral rubble send chemical cues that repel juvenile fish, while healthy coral colonies attract new recruits.
