Need to add content here that includes: overview, history of observed occurrences (when did scientists notice the problem?), list of algal species, impact on coral growth, other effects on reef diversity, estimated cover, etc.

Approaches to Managing Macroalgae

Scientists at the Mote Marine Lab are attempting to breed and release an herbivorous crab, 'Maguimithrax spinosissimus' or Caribbean king crabs, onto algal-dominated reefs to try and control algal growth. [1] A study in 2021 found that these crabs reduced algae cover by 50%-80%.[2]
