| Remarks | The species is physiologically tied to well-aerated water and is acutely sensitive to oxygen lack. Juveniles tend to aggregate inshore among vegetation, while the adults remain further out if there is a sandy substrate (Ref. 52346, Ref. 52960, Ref. 246). Predominant food is the lake-fly in its larval aquatic stages (Ref. 246). |
