Megamouth shark Baja California, Mexico, and samples taken from GenBank in order to perform a population genetic analyses of the megamouth shark; the results indicated no genetic diversity between populations found in different geographical locations, which indicates the species forms a single, highly migratory, interbreeding population. The first megamouth shark was captured on November 15, 1976, about 25 miles off the coast of Kāneohe, Hawaii, when it became entangled in the sea anchor of United States Navy ship "AFB-14".

On the basis of all relevant indicators it is necessarily to take urgent measures, continuous and organized action, to dramatically reduce the quantity (if is not possible to exterminate) of this allochthonous type of fish, as well as to attempt to revitalize autochthonal fish populations, with fish stocking of local, especially salmonids species, all in order to prevent the same fatal experience with the water ecosystem in the UK, and prevent, if possible, this type of allochtonous species colonization of the Neretva River basins with irreversible effects.
