Concept Reference Code: B91ROB01NAUS
Name Used in Concept Reference: Lampetra minima
Taxonomic Comments: Thought to have evolved from a stock of L. TRIDENTATA isolated in Miller Lake after the explosion of Mt. Mazama about 6,600 years ago (Kan and Bond 1981, Miller et al. 1989). However, subsequent data indicate a more ancient separation and a sister relationship with L. LETHOPHAGA (Lorion et al. 2000).

   NatureServe Status

Global Status: G1
Global Status Last Reviewed: 22Jan2001
Global Status Last Changed:  22Jan2001
Rounded Global Status: G1
Reasons:

Formerly thought to be endemic to Miller Lake, Oregon, where exterminated in early 1950s through chemical control measures to prevent predation by this species on trout; recent surveys documented this species in several areas within and outside the Miller Lake subbasin in Oregon.

Global Range Comments: Formerly thought to be endemic to Miller Lake (16 km northeast of Mt. Thielson), Klamath County, Oregon (Lee et al. 1980); last collected there in the early 1950s. Recent surveys documented populations in Miller Creek, Jack Creek, and the upper sections of the Williamson and Sycan rivers (Lorion et al. 2000).

Short General Description: A parasitic fish (lamprey).

Reproduction Comments: Spawning was observed June 10 at a water temperature of 12 C (Lorion et al. 2000). Relatively high fecundity (Miller et al. 1989).

Ecology Comments
Adults live more than one year (Lee et al. 1980).

Habitat Type: Freshwater

Non-Migrant: Y

Locally Migrant: N

Long Distance Migrant: N

Riverine Habitat(s): CREEK, MEDIUM RIVER

Lacustrine Habitat(s): Deep water, Shallow water

Special Habitat Factors: Benthic

Habitat Comments: A nest in the Sycan River was a pitlike clearing on a gravel-cobble substrate in a sand matrix in water about 30 cm deep and about 3 m from shore (Lorion et al. 2000).

Adult Food Habits: Herbivore, Invertivore, Piscivore

Immature Food Habits: Herbivore, Invertivore, Piscivore

Food Comments: Adults parasitic on fishes (trout, chubs, dace). Lamprey ammocoetes fed on detritus and algae.

Length: 13 centimeters

Population/Occurrence Delineation

---Jump to Section--- Classification Conservation Status Distribution Ecology & Life History Economic Attributes Management Summary Population/Occurrence Delineation Population/Occurrence Viability Authors/Contributors References

Group Name: NONANADROMOUS LAMPREYS

Use Class: Not applicable
Minimum Criteria for an Occurrence: Occurrences are based on evidence of historical presence, or current and likely recurring presence, at a given location. Such evidence minimally includes collection or reliable observation and documentation of one or more individuals (including eggs and larvae) in appropriate habitat.
Mapping Guidance: Occupied locations that are separated by a gap of 10 km or more of any aquatic habitat that is not known to be occupied represent different occurrences. However, it is important to evaluate migrations and seasonal changes in habitat to ensure that spawning areas and nonspawning areas for a single population are not artificially segregated as different occurrences simply because there have been no collections/observations in an intervening area that may exceed the separation distance.
Separation Barriers: Dam lacking a suitable fishway; high waterfall; upland habitat.
Separation Distance for Unsuitable Habitat: 10 km
Separation Distance for Suitable Habitat: 10 km
Separation Justification: Separation distance is arbitrary. Because of the difficulty in defining suitable versus unsuitable habitat, especially with respect to dispersal, and to simplify the delineation of occurrences, a single separation distance is used regardless of habitat quality.
