Bulbodacnitis alpinus sp. nov. is described from Salvelinus alpinus L. from the North Slope of Yukon and Alaska. Bulbodacnitis alpinus was found to be present in both anadromous and freshwater resident stream populations but it is absent from lake populations of S. alpinus. Specimens of B. occidentalis Smedley, 1933, B. scotti Simon, 1935, B. ampullastoma Maggenti, 1971, and B. truttae (Fabricius, 1794) were examined and comparative measurements are presented. Bulbodacnitis scotti, B. ampullastoma, and B. occidentalis are considered synonyms of B. truttae.

A New Species

Fourteen species of metazoan parasites were recovered from a total of 128 Salvelinus alpinus from the north slope of Canada and Alaska collected between March 31, 1971 and November 5, 1972. The parasites consisted of one monogean, four digeneans, four cestodes, two nematodes, one acanthocephalan, and two copepods. Of the parasites recovered, one was described as a new species (Bulbodacnitis alpinus Mudry and McCart, 1974) and three others are new North American host records (Tetraonchus alaskensis, Cystidicola stigmatura, and Cyanthocephalus truncatus). All of the localities sampled during this study are range extensions of the parasites found.

Two Samples

Samples from 11 populations of the Arctic char of the North-European part of Russia belonging to the anadromous and resident forms and two samples from Lake Sobach'e (Taimyr) were studied. The nucleotide sequence of the mitochondrial COI gene was determined in 60 individuals. In the majority of populations, the same COI haplotype was found. In some populations of the resident chars, haplotypes differing from the widespread haplotype in a single nucleotide substitution were found. The obtained genetic data give no reason to distinguish the resident form of the Arctic char from lakes of Karelia and the Kola Peninsula as an independent species, Salvelinus lep- echini. The adaptation of the Arctic char to the unstable environmental conditions is ensured primarily by its phenotypic plasticity.

AbstractThe North Slope of Alaska contains arctic fish populations that are important for subsistence of local human populations, and are under threat from natural resource extraction and climate change. We designed and evaluated four quantitative PCR assays for the detection of environmental DNA from five Alaskan fish species present on the North Slope of Alaska: burbot (Lota lota), arctic char (Salvelinus alpinus), Dolly Varden (Salvelinus malma), arctic grayling (Thymallus arcticus), and slimy sculpin (Cottus cognatus). All assays were designed and tested for species specificity and sensitivity, and all assays detected target species from filtered water samples collected from the field. These assays will enable efficient and economical detection and monitoring of these species in lakes and rivers. This in turn will provide managers with improved knowledge of current distributions and future range shifts associated with climate and development threats, enabling more timely management.

Freshwater Resident

Both anadromous and freshwater-resident populations of Arctic char (Salvelinus alpinus) occur in the Sagavanirktok River drainage, Alaska. A comparison of the gill-raker and pyloric-caeca counts of populations of the two types revealed that anadromous fish had lower gill-raker and pyloric-caeca counts than freshwater-resident fish. Freshwater-resident populations correspond meristically to McPhail's Eastern Arctic form, and anadromous population scor-respond to his Western Arctic–Bering Sea form (McPhail, J. Fish. Res. Bd. Canada 18: 793–816, 1961). It is suggested that the former was the original inhabitant of the area but has been replaced by the latter except in inaccessible, headwater lakes.

Perennial springs in arctic drainages are used extensively by freshwater-resident and anadromous segments of Arctic char (Salvelinus alpinus) populations. Movements of these fish were monitored in a small spring on the Canning River from May 23 to October 7, 1973, dates approximating spring breakup and winter freeze-up in the drainage. Char passing through the weir ranged in size from 22-mm fry to 595-mm anadromous spawners, though most fish were juveniles measuring 60–200 mm. The spring channel was utilized as (1) a spawning area for anadromous spawners and residual males in autumn, (2) a rearing area for fry and some older juveniles in summer, and most importantly (3) an overwintering area for juvenile char, especially those in their first and second winters of life.
