Ecology Summary - Lethenteron camtschaticum

Language:

Main Ref.	Holcík, J., 1986
Remarks	Prefers sites with stony or sandy bottom, shaded by riparian vegetation (Ref. 41072). Spawning adults found in gravel riffles and runs of clear streams; feeding adults usually in oceans or lakes; ammocoetes in muddy margins and backwaters of river and lakes (Ref. 5723). Anadromous (Ref. 58426). There are non-migratory freshwater populations. Subadults are non-parasitic (Ref. 12218). Feed on small aquatic invertebrates, algae and organic matter contained in detritus (Ref. 41072). Some populations are anadromous while others are permanent freshwater residents. Larvae dwell in soft silty substrates of streams, rivers and lakes. Feeding and spawning migrations range from 200 - 2,100 km (Ref. 117245).

Associations

Ref.	Renaud, C.B., 2011
Associations	parasitism;
Associated with	Catostomus catostomus, Coregonus artedi, C. clupeaformis, Salvelinus namaycush, Stenodus leucichthys
Association remarks	Adults often parasitic, attach themselves to other fish with the sucker-like mouth, gnaw open skin of the fish with their horny teeth and suck their blood and meat (Ref. 45563). Probably parasitizes any species of fish of suitable size (Ref. 27547), including commercial species (Ref. 58426). Adults parasitic on various fishes in both fresh and marine waters. The site of attachment is usually below the lateral line and anterior to the pelvic fins (Ref. 89241).
