The cunner (Tautogolabrus adspersus), also known as the blue perch, bergall, chogset, choggie,[2] conner or sea perch,[3] is a species of wrasse native to the northwestern Atlantic, where it is found from the Gulf of St. Lawrence and Newfoundland to the Chesapeake Bay. They inhabit inshore waters living near the sea floor at depths from 10 to 128 m (33 to 420 ft), preferring areas with beds of seaweed, shipwrecks, or wharf pilings. They spend the winter months in a state of torpor underneath rocks. They can also be found in the aquarium trade.[4]
Often, cunner is found mixed in with tautogs, living on or near the same structures. Much of the food eaten by those bergall living among blackfish are the leftovers from the blackfishes prey. They can be distinguished from the tautog by their pointed snouts. Cunners are generally smaller, so are usually thrown back by anglers who think they caught a "short" tautog. In past years, they have been important commercial fish, but now are considered pests. They can be confused with black sea bass, rockfish and other grouper, as well as tautog, for their ability to change color.
Cunner can enter a hypometabolic state in response to cold temperatures and hypoxic conditions.[5] In Newfoundland, Canada, cunner have been recorded entering a dormant state in Autumn, when temperatures fall below 5°C, and remaining dormant until May/June.[5]
Tautogolabrus adspersus is currently the only known member of its genus.[4]
On May 26, 2019, the NJDEP Division of Fish and Wildlife officially certified the catch of a new state record saltwater fish, weighing 3 pounds, 8.8 ounces, eclipsing the previous state record by 6.4 ounces. The fish measured 18.5″ in length and had a girth of 13″.[6]

Tautogolabrus adspersus est une espèce de poissons marins de la famille des Labridae.
On appelle ce poisson tanche-tautogue, mais aussi achigan de mer, vieille, perche de mer ou tanche vieille. Ses noms anglais: cunner, perch, sea perch, blue perch, bergall ou nipper.
Côte atlantique de l'Amérique du Nord. Du nord de Terre-Neuve, du sud du golfe du Saint-Laurent et des bancs du large jusqu'à l'embouchure de la baie de Chesapeake au sud.
La tanche-tautogue peut atteindre un poids de 1,5 kg et ne dépasse pas généralement la taille de 30 cm. Sa couleur varie selon la nature du fond: elle présente différentes taches de brun, de rougeâtre et de bleu, l'une de ces couleurs étant prédominante; un peu de vert olive terne se présente à l'occasion. Le rougeâtre se retrouvant souvent sur les sujets en eau profonde. Le ventre présente des reflets bleuâtres, parfois blanchâtres. Chez les exemplaires de 10 cm ou moins, apparaît une tache blanche, près de la nageoire dorsale, juste derrière la dernière épine. La tanche-tautogue a une nageoire dorsale continue, avec des épines en avant et des rayons mous en arrière. La bouche, armée d'une bonne denture, est petite et la queue arrondie. La tanche-tautogue ressemble à son cousin le tautogue noir, qui est plus robuste, plus foncé et moins coloré, de plus grande taille et avec un museau plus arrondi jusqu'à la base de la nageoire dorsale.

Tautogolabrus adspersus (Walbaum, 1792), l'unica specie facente parte del genere Tautogolabrus, è un pesce di acqua salata appartenente alla famiglia Labridae[2].
Proviene dall'ovest dell'oceano Atlantico, dove è stato localizzato soprattutto dall'isola di Terranova, lungo le coste del Canada, nella Baia di Chesapeake[3] e nel golfo di San Lorenzo[2]. Vive soprattutto vicino alla costa, in particolare in inverno, quasi sempre in zone rocciose[1]. È comune vicino ai moli ed ai relitti[3]. Può essere trovato fino a 120 m di profondità[1].
Presenta un corpo compresso lateralmente, allungato e non particolarmente alto, con la testa dal profilo appuntito. Le pinne sono ampie, alte, ma non molto allungate e hanno sfumature che tendono al rosso; la pinna caudale non è biforcuta. Non supera i 38 cm per 1 kg di peso, e vive fino a 6 anni[3]. La colorazione è variabile[4].
Può formare banchi[1].
È una specie carnivora che durante l'inverno smette di nutrirsi[2]. La sua dieta è molto varia e comprende sia resti di animali morti[5] che invertebrati vivi, tra cui echinodermi, soprattutto ricci di mare[6] e vermi, di solito anellidi policheti. Altre prede sono molluschi bivalvi e gasteropodi, crostacei anfipodi (Unciola), isopodi e gamberi (Pandalus)[5]. Si nutre anche di tunicati, soprattutto ascidie[7].
È oviparo e la fecondazione è esterna. Le uova, trasparenti e galleggianti, vengono deposte tra luglio e agosto[2] e impiegano da 40 ore a 3 giorni per schiudersi[1].
È classificato come "a rischio minimo" (LC) dalla lista rossa IUCN perché oltre alla cattura durante la pesca sportiva non è minacciato da particolari pericoli[1].
