Whale sharks survive on a diet mainly consisting of plankton, as well as other smaller prey like jellyfish, crab, squid, mackerel, and krill. [14] Nutrient removal by shellfish, which are then harvested from the system, has the potential to help address environmental issues including excess inputs of nutrients (eutrophication), low dissolved oxygen, reduced light availability and impacts on eelgrass, harmful algal blooms, and increases in incidence of paralytic shellfish poisoning (PSP).
