Due to its amphidromous nature, as known to occur with its congeners (adults live and breed in freshwater streams; larvae hatched drift downstream and develop in marine environments; juveniles return to freshwater streams), blockage of the migration pathway (e.g. construction of dam or culvert in streams) would cause a significant impact on this species. Ensuring no net loss of habitat, keeping the natural stream flow and maintaining the stream-ocean corridor are all essential for preserving this species (based on researches on its congeners; see Ref. 82683, 82684, 82685, 82689, 82690, 82692). Collection conducted by aquarium hobbyists (both private and commercial) also poses a serious threat to Stiphodon species in some regions (Ref. 82684) and this kind of activity should be strictly controlled (Ref. 82694).

Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).
