NatureServe Global Conservation Status Factors

Range Extent: 200,000-2,500,000 square km (about 80,000-1,000,000 square miles)
Range Extent Comments: Range includes the Ohio River basin, from extreme southwestern New York west to Indiana and (at least formerly) Illinois, south to northern Georgia (Page and Burr 2011).

Number of Occurrences: 21 - 80
Number of Occurrences Comments: Number of occurrences (subpopulations) is not precisely known; likely there are at least 21-80. Lee et al. (1980) mapped 71 collection sites from 17 rivers in the Ohio River drainage; some of these do not now have extant breeding populations. Additional sampling is likely to yield new occurrences, as recently demonstrated in Alabama (Mettee et al. 1996). TNHC (1996) mapped 55 collection sites including: 7 from Pennsylvania, 6 from Ohio, 7 from Indiana, 3 from Illinois, 2 from West Virginia, 1 from North Carolina, 13 from Tennessee, 7 from Kentucky, and 3 from Alabama. Collected for the first time in North Carolina during 1994-1995 from 2 locations on Spring Creek (Rhode et al.).

Population Size: Unknown
Population Size Comments: Total adult population size is unknown. This species is generally uncommon (Page and Burr 2011). Populations can fluctuate greatly.

Number of Occurrences with Good Viability/Integrity: Unknown

Overall Threat Impact: Medium
Overall Threat Impact Comments: Threats include habitat degradation, especially of spawning streams, due to pollution, siltation, and hydrological alteration.

Short-term Trend: Decline of <30% to relatively stable
Short-term Trend Comments: Trend over the past 10 years or three generations is uncertain but probably relatively stable or slowly declining.

Long-term Trend: Decline of <50% to Relatively Stable
Long-term Trend Comments: Distribution and abundance likely have declined, but the degree of decline is unknown.

Intrinsic Vulnerability: Moderately vulnerable

Other NatureServe Conservation Status Information

Inventory Needs: Determine abundance and number of occurrences.

Protection Needs: Maintain adequate spawning habitat and host populations.

Basic Description: A parasitic lamprey.
Reproduction Comments: Larval stage lasts about 4 years, adult stage about 23 months. Spawns at beginning of second summer as adult, then dies (Lee et al. 1980).
Habitat Type: Freshwater
Non-Migrant: N
Locally Migrant: Y
Long Distance Migrant: N
Mobility and Migration Comments: Migrates between separate larval and adult habitats.
Riverine Habitat(s): BIG RIVER, CREEK, High gradient, Low gradient, MEDIUM RIVER, Moderate gradient, Pool, Riffle
Special Habitat Factors: Benthic
Habitat Comments: Adults inhabit medium to large rivers, larvae burrow near debris in mud bottom of quiet pools of creeks and small rivers (Lee et al. 1980). Eggs are laid in nests in gravel-bottomed riffles in small gravelly tributaries.
Adult Food Habits: Herbivore, Invertivore, Piscivore
Immature Food Habits: Herbivore, Invertivore, Piscivore
Food Comments: Adults are parasitic on fishes (e.g., carp, smallmouth buffalo, longnose gar) (Mettee et al. 1996), larvae eat plankton (Smith 1979).
Length: 27 centimeters

Population/Occurrence Delineation
Help
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.
