Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 16 - 17; членистые (мягкие) лучи спинного плавника (общее число) : 10; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 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).
