生物学特性     字汇 (例如 epibenthic)

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).

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | | 孕卵数 | 仔鱼

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).
