Language English Photo: Biodôme OngletsDescriptionDistinguishing featuresThe longnose sucker has a long, cylindrical body and a ventral mouth with thick lips. Its back and upper sides are generally dark, while the lower sides and belly are pale. ReproductionIt spawns in the spring, between mid-April and mid-May, as soon as the temperature rises above 5ºC. Spawning is often in shallow water, in gravel-bottom streams. The female lays from 17,000 to 60,000 eggs. DietThey feed on a wide variety of bottom-dwelling invertebrates: insect larva, small crustaceans and gasteropods. They also eat algae. PredatorsYoung longnose suckers are eaten by different fish and birds. Larger specimens fall prey to northern pike. When spawning, adults are vulnerable to bears and eagles. HabitatThis fish is found almost everywhere in Canada and the northern United States. It is the only catostomidae found in both North America and Asia. It lives in cold waters at the bottom of lakes and rivers, and sometimes even in brackish water. Ecology, behaviourAt spawning time, two to four males flank the female and clasp her or vibrate against her. Each spawning act lasts only 3 to 5 seconds, but is repeated up to 40 times an hour.
