The Bloater fish lifestyle

The Bloater fish mainly feeds on animals living at the bottom of the lake (zoobenthos), but sometimes eats small drifting animals, or zooplankton.
Spawning occurs all year round, but usually in winter or fall. Spawning occurs at depths of 37 to 92 meters. The number of eggs produced by the female varies according to her size and ranges from 3,230 to 18,768. The eggs incubate for 4 months and the bloating is 1.01 cm long at hatching. Larval bloater moves to the cold bottom of lakes before becoming pelagic and, from their first summers, they become bottom dwellers. Larval bloating has a high mortality rate until it becomes large enough to avoid predation by other bloating and alewives. It grows slowly due to the scarcity of food in its habitat. The average length of the balloon at maturity is 18.3 centimeters.

The Bloater fish habitat

The bloater fish lives is at a depths of 30 to 198 meters. There, it lives on underwater slopes and tolerates temperatures between 1.5 and 11.4 degrees Celsius. When it come to the surface, its gas bladder expands, giving it a swollen appearance.
The bloater originates from all the Great Lakes (except Lake Erie) and Lake Nipigon. It is in decline throughout its range and the IUCN Red List classifies it as vulnerable to global extinction. It has disappeared from Lake Ontario and Lake Nipigon, is rare in Lake Michigan and is declining in Lakes Superior and Huron. This decline is mainly caused by alewife predation, predation and lamprey pollution.
