Ichthyomyzon castaneus
Chestnut Lamprey
Type Locality
Galena, Minnesota (Girard
1858).
Etymology/Derivation of Scientific Name
Ichthyomyzon, Greek,
“sucker of fish”; castaneus, Greek, “of chestnut color.” (Pflieger
1997).
Synonymy
Ichthyomyzon castaneus
Girard 1858:381 in C.L. Hubbs and Potter 1971; Suckley 1860 in Smith
1979; Hubbs and Trautman 1937; Cook 1959:44.
Characters
Maximum size: 380 mm
TL (Carlander 1969).
Coloration: Juveniles
and adults are dark grey to brown along the back, becoming lighter on the
belly. The sides may be mottled or slate colored. After spawning the
coloration is more bluish black. Ammocoetes are gray along the back with
lighter undersides; usually have pigmentation under the eyes and in front of
the gill region. The lateral line pores are generally unpigmented in the
ammocoetes, juveniles, and adults, but becomes progressively darker in
larger individuals (Ross 2001).
Counts: 51-54 (47-56)
myomeres; 2-3 (1-4) supraoral cusps; 6-11 infraoral cusps; 3-5 anterior
teeth, and 6-9 (6-11) lateral teeth (Ross 2001).
Body shape: In
southern members of this species, the body is less deep, eye smaller, and
snout longer than those in the more northerly part of range (Knapp 1951).
Adults with well developed intestine (Hubbs et al. 1991). Inner lateral
(circumoral) teeth are bicuspid (Ross 2001).
Mouth position:
Subterminal in both ammocoete and adult (Goldstein and Simon 1999).
External morphology:
Disc large; length of disc contained 14.3 times in total length; cusps in
posterior field not degenerate (Hubbs et al. 1991). Dorsal fin continuous,
except for a small notch; dorsal fin height increases several fold after
metamorphosis. Mature males develop an elongate urogenital papilla (Ross
2001).
Distribution (Native and Introduced)
U.S. distribution:
West central Manitoba along Red River of the North, and in the Mississippi
River and the Great Lakes southward to Mobile Bay (Hubbs et al. 1991).
Texas distribution:
This parasitic species occurs in east Texas streams of the Red, Sabine, and
Neches basins (Hubbs et al.1991; Warren et al. 2000). Toole (1950) noted a
parasitic lamprey provisionally identified as I. castaneus, was sent
to him by Paul Whaley of Marshall, who caught it in Caddo Lake (on the
Texas-Louisiana border in the Red River watershed). Two immature specimens
were sent to Texas A&M College; the larger specimen (Cat. No. A-1-b-3, spec.
No.1) measuring 165.6 mm TL, found by Wayman V. Wilson of Atlanta, Texas, on
a chain pickerel (Esox niger) caught by him in Smith Slough, Caddo
Lake, March 13, 1950; the smaller specimen (Cat. No. A-1-b-2, spec. No.1)
measuring 141.0 mm TL, taken by Paul Whaley of Marshall, TX, caught on a
bass in Caddo Lake, TX, March 20, 1950 (Knapp 1951).
Abundance/Conservation status (Federal, State, NGO)
Not listed as threatened or
endangered by Texas Parks and Wildlife Department
(2006). Populations in the
southern United States are currently secure (Warren et al. 2000).
Habitat Associations
Macrohabitat: Adults
usually encountered in large reservoirs and rivers, generally not found in
smaller streams characteristic of the ammocoete stage (Scott and Crossman
1973; Rohde and Lanteigne-Courechene 1980). Ammocoete live in streams
(Carlander 1969).
Mesohabitat:
Ammocoetes stay in swifter water in fine substrata, as well as in slower
area with vegetation (Scott and Crossman 1973).
Biology
Spawning season: In
Tennessee, occurs in early May (Etnier and Starnes 1993).
Spawning habitat:
Lithophils; rock and gravel spawners that do not guard their eggs. Large
eggs are buried in gravel depressions called redds or in rock interstitial
spaces (Simon 1999); gravel beds (Carlander 1969).
Reproductive strategy:
Non-guarders; brood hiders (Simon 1999). Build nests in gravel areas of
streams and die shortly after spawning (Carlander 1969). Spawning occurs in
large communal aggregations of up to 50 individuals (Ross 2001). The
spawning fish excavated a nest area 60cm wide by 100 cm long, and 5 cm deep.
While some fish engaged in spawning, others moved stones from the upstream
side of the nest, so the over the course of about 22 hours the nest area
including newly excavated and filled extended 6.2m upstream from the
original site (Case 1970).
Fecundity: A 284 mm
female from Oklahoma reported to contain 42,000 eggs (Hall and Moore 1954).
Fecundity increases with adult size ranging from 10,144 to 18,563 oocytes;
mature ovarian oocytes average 1.34 mm in diameter (Beamish and Thomas
1983).
Age at maturation:
Ovaries begin to show development in ammocoetes larger than 88 mm TL
(Beamish and Thomas 1983).
Migration: Most adults
migrate to lakes, oceans, or large rivers (Carlander 1969).
Growth and population
structure: Postmetomorphosis juveniles may be less than 100 mm TL;
adults range between 105-310 mm TL Ross 2001). In May, lampreys averaged 104
mm and 1.8g; in October, 201 mm and 9.1 g (Carlander 1969). Ammocoetes
metamorphose into predaceous juveniles between 100-130 mm TL and at 5-7
years (Hardisty and Potter 1971). Juvenile stage lasts from less than a year
to no more than 1.5 years (Hall 1963).
Longevity: Adults, in
Michigan, reported to live 18 months, but to feed actively for only five
months (Carlander 1969).
Food habits:
Ammocoetes are herbivorous filter feeders consuming minute organic particles
(Diatoms and desmids) for several years prior to metamorphosing into adults.
Adults are parasitic carnivores, feeding on the blood of other fish by
attaching themselves with a suctorial disc and rasping a hole with their
horny plated tongue (Carlander 1969; Goldstein and Simon 1999). Host species
include chain pickerel (Esox niger), carp, blacktail redhorse (Moxostoma
poecilurum), channel catfish (Ictalurus punctatus), green sunfish
(Lepomis cyanellus), and largemouth bass (Micropterus salmoides;
Hall and Moore 1954; Farmer 1980; Mayden et al. 1989). Cook (1959) also
reported it on catfish, buffalos, and paddlefish (Polydon spathula).
Recently studies showed them feeding on smaller fishes (130-150 mm TL)
including creek chubs (Semotilus atromacutalus), bluegills (Lepomis
macrochirus) and common shiners. Small fish are more common upstream
where metamorphose to adult stage occurs, and their scale and skin layers
allow easier easier penetration for smaller lampreys (Cochran and Jenkins
1994). Most parasitic attacks take place at night (Hall 1963).
Phylogeny and morphologically similar fishes
Icthyomyzon castaneus
is thought to be derived from I. unicuspis (Hubbs and Potter 1971).
The chestnut lamprey is most
similar to the southern brook lamprey. The chestnut lamprey can be
distinguished in adult form by the presence of well developed teeth in the
oral disk (versus poorly developed teeth in the southern brook lamprey), by
the oral disk being wider than the head, and by the functional digestive
tract (Ross 2001).
