Yellow-band disease

[2] It is characterized by large blotches or patches of bleached, yellowed tissue on Caribbean scleractinian corals.

Under certain water conditions, like fluctuating temperatures and increased nitrogenous waste, corals will appear stressed.

The bacteria produces the characteristic pale yellow lesions and eventually kills the zooxanthellae by impairing its mitosis and its ability to carry out photosynthesis.

[9] Compared to the late 1990s, current data suggests that the disease remains a severe epidemic.

In one study, 10 meter belt transects were taken at various depths, sampling coral colonies in the Lesser Antilles.
