Salmincola lotae Olsson, 1877

Common name: parasitic copepod

Synonyms and Other Names: Lernaeopoda lotae

Identification: This stout and square parasitic copepod is found in the oral cavities of its host fish. It exhibits a maxilliped with subchela that ends as a solid claw. The claw is associated with a long papilla. The copepod possesses a large, flat, and round bulla associated with two maxillary arms. The bulla is typically implanted near bone or cartilage of the host fish. At the termination of the antennae, there are hook-like processes on the endopods. The 2nd maxilla is relatively long and is implanted up to 2/3rds of its length in cavities of 5–8 mm in host tissue (Lasee et al. 1988; Hudson et al. 2003).

Size: range in length from 5.5–6.5 mm (Hudson et al. 2003)

Native Range: Salmincola lotae is native to Eurasia and has been recorded in the Palearctic region in Sweden, Finland, and northern Russia (Bagge and Hakkari 1982; Hudson and Bowen 2002; Grigorovich et al. 2003; Hudson et al. 2003).           

See Remarks section for discussion of uncertainties regarding native range.

Nonindigenous Occurrences: Salmincola lotae was recorded from the Apostle Islands region of Lake Superior in 1985 in host burbot (Lota lota) (Lasee et al. 1988).

Ecology: Salmincola lotae infects the oral cavity of the burbot (Lota lota) in North America and Eurasia. It probably feeds on mucous and epithelial cells, shredding its host’s epidermis. In Finland, it occurs in burbot at depths of 50–100 m in Lake Paijanne (Bagge and Hakkari 1982; Lasee et al. 1988; Hudson et al. 2003).

Means of Introduction: Unknown.

Status: Reported from Lake Superior. See Remarks.

Impact of Introduction:  

A) Realized: In Lake Superior S. lotae has been known to cause relatively large lesions in the mouth of L. lota where the bulla is implanted. Around 56% of burbot in the Apostle Islands region have been infected at a given time with on average 3.6 parasites per fish. Most often, L. lota in Lake Superior have exhibited infection in the roof of the mouth behind the vomerine teeth (Lasee et al. 1988; Hudson et al. 2003).           

B) Potential: Unknown.

Remarks: This species has also been recorded in burbot from the Northwest Territories, Canada (Stewart and Bernier 1983, 1999), although there is some question over the validity of records (McDonald and Margulis 1995; Hudson et al. 2003). In spite of this, some experts have recently begun to consider that S. lotae may actually be native to the Nearctic region and thus could be native to Lake Superior (Reid and Hudson 2008).           

Salmincola lotae is synonymous with Lernaeopoda lotae.
