Epidemi Urchin yo pi byen jere pa adrese kòz yo kache, tankou twòp lapèch nan predatè oswa èbivò, oswa polisyon eleman nitritif. Nan kèk sikonstans, sepandan, rediksyon rapid nan densite pichpen yo ka dezirab pou fasilite rekiperasyon popilasyon koray yo kòm yon pati nan yon estrateji restorasyon an. Esè jesyon, tankou sa ki nan Seselwa yo, te endike ke rekritman koray ka ogmante jiska de-pliye nan sit kote eri yo te retire. ref Nan Kenya, eksperyans yo endike tou ke remokaj gen benefis nan koray, men ke sa a ka anvan pa yon premye ogmantasyon nan abondans alg epi yo dwe akonpaye tou ak pwoteksyon pwason ki prizonye. ref

Urchin outbreaks are best managed by addressing the underlying causes, such as overfishing of predators or herbivores, or nutrient pollution. In some instances, however, rapid reductions in urchin density may be desirable to facilitate recovery of coral populations as part of a restoration strategy. Management trials, such as those in the Seychelles, have indicated that coral recruitment can increase up to two-fold at sites where urchins were removed. ref In Kenya, experiments also indicated that urchin removal can benefit corals, but that this can be preceded by an initial increase in seaweed abundance and must also be accompanied by protection of fishes that prey on urchins. ref
