Proto-Altaic: *suku ( ~ z-, -o-)
Meaning: a k. of fish
Russian meaning: вид рыбы
Comments: The comparison with Jpn. sakana 'fish' in JOAL 98 should certainly be rejected (the only meaning of sakana attested in OJ is "food (vegetables) eaten with sake", thus the modern meaning 'fish' is obviously secondary). Cf. *sàk`ò.
