| Các chú thích | Migrating inshore to breed, but without any strong north-south migrations, the populations being localized. Apparently landlocked populations (races) exist in the lakes of South Sakhalin, eastern Hokkaido and eastern Honshu. Salinity resistance (min. 1.5%) is maximal in newly hatched larvae and fry, and minimal in larvae of 20-30 days old (Ref. 6507). Pelagic and neritic. Schooling species. Moves vertically at the water column, surfacing in the evening and descending at dawn. Found in nearshore areas; in harbors, inlets, bays and brackish estuaries when spawning; and may enter fresh water. Biological anti-freeze enables tolerance to below zero temperatures up to -1.4°C. Feeds on crustaceans, benthic infauna, foraminiferans, plant materials, and fishes (Ref. 117245). |
