Scribbled Goby

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).

Found in streams and rivers. Enters estuaries (Ref. 4833). Usually associated with streams having a gravel or sand substrates. Feeds mainly on filamentous algae and Diptera (Ref. 6028) and also small fishes and crustaceans (Ref. 12693). Not seen in market, but probably sold fresh (Ref. 12693).
