Descripció[modifica]

Reproducció[modifica]

És ovípar amb ous demersals i adhesius, i larves pelàgiques.[5][6]

Menja principalment larves d'insectes aquàtics i invertebrats bentònics.[7]

Depredadors[modifica]

És depredat per Ptychocheilus oregonensis, Coregonus clupeaformis, Salvelinus malma, Salvelinus namaycush i Mergus merganser americanus.[8][9]

Hàbitat[modifica]

És un peix demersal i de clima temperat (60°N-32°N).[2][10]

Distribució geogràfica[modifica]

Es troba a Nord-amèrica: conques pacífiques des de Seward (Alaska) fins al riu Ventura (Califòrnia).[2][11][12][13][14][15][16][17][18][19][5][20][21][22][23][24][25][26][27][28][29]

Longevitat[modifica]

La seua esperança de vida és de 7 anys.[30]

Ús comercial[modifica]

És massa petit i molt difícil de capturar en grans quantitats com per a ésser emprat com a aliment o en qualsevol altra cosa. Tot i així, els exemplars grossos són bons com a esquers i una menja excel·lent.[31][32]
