were stored in the sediments, and are stillbeing released even after 30 years. Thereis also evidence that fishing has reducedpopulations of fishes that graze on bubblealgae. Furthermore, the grazing fishesthat remain prefer to eat other species of seaweed that have been introduced fromoutside Hawai‘i, and have shifted away from eating bubble algae. Thus, bubblealgae may be abundant because they arenot being eaten as fast as they once were. Another introduced seaweed, which likebubble algae is not a preferred food of herbivorous fishes, has also started toproliferate and smother corals in the bay (Fig. 14.13). It will be much harder to re-store the coral gardens of Kane‘ohe Bay than it was to destroy them
