生態学
海; 汽水性の 関連する礁; 深さの範囲 1 - 75 m. Subtropical; 46°N - 31°N, 81°W - 58°W
Western Atlantic: slightly east of Halifax in Nova Scotia, Canada to South Carolina in USA; most abundant between Cape Cod and Delaware Bay.
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 23.6, range 18 - 26.5 cm
Max length : 91.0 cm TL オス/雌雄の選別がない; (Ref. 7251); 最大公表体重: 11.3 kg (Ref. 40637); 最大記録サイズ: 34 年 (Ref. 6486)
背面の脊椎 (合計) : 16 - 17; 背鰭 (合計) : 10; 肛門の骨: 3; 臀鰭: 7 - 8. Distinguished from Tautogolabrus adspersus which occurs in the same area and further north, by its steep, rounded dorsal head profile; stouter body; scaled lower gill cover; and the more backward location of the pelvic fins.
Found close to shore on hard-bottom habitats, occasionally entering brackish water. Adult male territorial and active during the day to feed and rests in crevices at night. Prefers temperatures above 10°C. Spawning was noted in June-July in Canadian waters, but appears more protracted (April-July) in coastal waters of Virginia, USA. Feeds mainly on mussels, gastropods, other mollusks and crustaceans. This species has gained popularity as a prized food and sport fish (Ref. 6486, 4926, 41297). Investigation on the diel and seasonal activity patterns of the adult tautog in its southern range were conducted using ultrasonic telemetry (Ref. 41297).
Spawns in groups or in pairs. Pairing occurs between females and size-dominant males exhibiting strong territoriality and performing a protracted courtship (Ref. 6488). Gonochorism is confirmed for this species (Ref. 103751).
