[9] Multiple North American fishery agencies have aided in the bloater's return to the lake, due to the positive impact it could have on its food web.

Recent studies have shown that this fish has made a surprising comeback, and it is now re-established in Lake Ontario.

[10] State, provincial and federal agencies aim to stock 500,000 Coregonus hoyi into Lake Ontario by the year 2015.

Dr. Hoy collected the first specimens of this species in 1870 while dredging in Lake Michigan at least 16 miles (26 km) off Racine, at depths of 50 to 70 fathoms (90–130 m).

[4] The generic name Coregonus, given by Carl Linnaeus in his 1758 tenth edition of Systema Naturæ, is derived from Greek and means "angled eye", referring to the tilted pupil of whitefishes.

[14] The bloater is one of the several taxa in the Coregonus artedi complex of freshwater whitefishes, which sometimes all are considered to belong to a single species.

The shrimp Mysis diluviana, and the amphipod Diporeia hoyi, also named after P. R. Hoy, are recorded as food items.

[12] Since most of the other "chubs" of the Great Lakes have become extinct, the average size of the bloater has increased, and it is caught and smoked in the United States.

[7] The bloater's average length at maturity is 18.3 centimetres (7.2 in), and maximum age reported from otoliths is 10 years.
