Migration
provided by Fishbase
Amphidromous. 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).

- Estelita Emily Capuli
Trophic Strategy
provided by Fishbase
Lives over sandy bottoms, regularly entering freshwaters during breeding season (Ref. 3479). Occurs in both estuarine and offshore waters but has been recorded as regularly entering freshwater for breeding purposes (Ref. ). Feeds mainly on crustaceans (especially shrimps), small fishes and benthic organisms.
