🐟Largemouth bass

Micropterus salmoides (Lacepède, 1802)

Isobassi (Micropterus salmoides) on Pohjois-Amerikasta kotoisin oleva aurinkoahvenkalalaji. 1800-luvulla sitä yritettiin siirtoistuttaa Suomeen, mutta kokeilu epäonnistui isobassille liian karujen olojen vuoksi. Isobassin saalistajia luonnossa ovat ihmisen lisäksi ainakin haikarat ja kirjokalastaja sekä hauki, jättihauki, kelta-ahven ja valkosilmäkuha.
