Settlement Plates
What are settlement plates?
- Suitable strata for corals to settle and grow
- Devices used to determine health of coral reefs (more recruitment, more reef growth)
- Density and Recuitment
- Can be used to determine spawning events
- Locations
- Coral Reefs
- Horizontal
- Vertical
- Different depths
- Artificial reefs
- Reef balls
- Coral Reefs
- Types
- Ceramic tiles (finished, unfinished)
- best option
- gap habitat
- Petri Dishes
- Glass
- Dead branching coral
- Slices or blocks of stony coral
- Ceramic tiles (finished, unfinished)
What do settlement plates measure?
- Coral recruitment
- Health of coral reef
- Scientists don’t know much about the coral reproduction process
- Phi Phi Islands case study (recruitment after tsunami)
How are settlement plates used?
- Methods and different types of Settlement plates [1]
- Similar Depth
- Similar attachment mechanisms
- Wire mesh
- Steel bolts
- Place the settlement plates before a known spawning period or leave them there for a complete season cycle
- Label, bleach, dry
- Examine with a dissection microscope
- Why use Settlement Plates [2]
- Able to be removed from reef
- Yields comparable data to natural reef substrata without damaging the reef
