| Notas | Found near shore and in coastal inlets and rivers (Ref. 2850). Possibly to 625 m depth (Ref. 6793). Spends most of its life in the sea, returning to freshwater streams to spawn (Ref. 27547). There is evidence of return to natal streams (Ref. 10276). May migrate up to 160 km upstream. Feeds on plankton and only while at sea (11699, 10276). Ecotoxicology of this species has been studied by various authors indicating that it is a potential integrator of low-level contaminants (Ref. 7355 & 7469). |
