Common names: Spot
Occurrence: native
Salinity: brackish
Abundance: | Ref:
Importance: minor commercial | Ref: FAO, 1994
Aquaculture: | Ref:
Regulations: | Ref:
Uses: bait: yes;
Comments: Present in the continental shelf waters off the northeastern United States (Ref. 37512). This species is one of big five historically associated with the commercial fisheries of the lower Chesapeake Bay and the North Carolina sounds. It is taken by haul seine, gill net, and pound traps. Although its current market value is as a live bait fish, it remains in demand as a food fish (fried or salted and boiled) for the older generation. Spot generally exit the Chesapeake before cold weather. In unusual situations, however, they linger and if there is a cold snap, it can succumb in large numbers (Bernie Herman - blherman@email.unc.edu, pers. comm. 01/12).

生物學特性     字彙 (例如 epibenthic)

Found usually over sandy or muddy bottoms in coastal waters to about 60 m depth. Occurs in nursery and feeding grounds in river estuaries during summer and fall. Juveniles often stay in the estuarine waters throughout the year. Feeds mainly on worms, small crustaceans and organic detritus. A small specimen of this species was caught in Tokyo Bay, Japan, probably brought in with the ballast water of a ship (Ref. 10325).

在沿岸水域中通常發現在沙底或泥底上到大約 60 公尺深。 夏天與秋天時在河口中出現於育幼與覓食場。 稚魚時常停留在河口的水域中全年度。 主要吃蠕蟲,小型甲殼動物與有機的碎屑。 這種的一種小的標本於東京灣,日本捕獲, 可能和船的壓艙水引進。 (參考文獻 10325)
