Acipenser oxyrinchus oxyrinchus

(American Atlantic Sturgeon)

Overview

[ Back to top ]

Family : Sturgeons ; Inhabit shallow waters of continental shelf. Ascend coastal rivers to spawn . Eggs demersal , measuring 2.55 mm in diameter and hatching in 1 week at 17.8¦C[1]. Juveniles may remain in fresh or brackish water until 3-5 years of age or 76-91.5 cm long[2]. Females take 8 to 30 years to reach sexual maturity and spawn only every 3-4 years. Exact time of spawning depends on temperature [3]. Used smoked and fresh[4].

Ecology: The Atlantic sturgeon (A. o. oxyrinchus) is a large anadromous species that historically ranged along the Canadian and U.S. Atlantic Coast from Labrador to Florida. This subspecies is recorded to live for up to 60 years and reach a size of 4.3 m and 368 kg (Vladykov and Greely 1963), though most mature fish are considerably smaller. Spawning occurs in fresh or slightly brackish water when water temperatures reached 13–18?C. Migrations into coastal tidal rivers begin as early as February in the southern portion of the range and continue through June and July in northernmost waters. In the mid-Atlantic area, Atlantic sturgeon males mature at 6–10 years and females at 10–20 years (ASMFC 1990). Maturation occurs earlier in southern waters and later in Canada. Spawning periodicity ranges from 2–6 years. Based on tagging studies ocean migrations of up to 1,450 km have been recorded (Dovel and Berggren 1983).[6].
