High nitrate levels are specifically toxic to corals, while phosphates slow down skeletal growth. Ocean acidification a result of increased CO2 : causes a reduction in pH levels which decreases coral growth and structural integrity. These results provide additional insight on the relationship between these reef fishes and their environment, can inform discussions of essential fish habitat for these large-bodied reef fishes, and can provide information for managers in their efforts to implement ecosystem-based approaches to fishery management.
Corals need to attach to a hard surface. Finally, Holland et al.
These same authors found that green jobfish Aprion virescens were seasonally attached to core areas of up to 12 km in length. Received May 11; Accepted Jan 8. At local, regional, and international scales, marine resource management is moving toward a suite of ecosystem-based management approaches including spatial closure and the protection of Essential Fish Habitat .
We will learn more about this topic and how it is related to ocean acidification in later units.
