Nonprotein nitrogen compounds in harp seal (Phoca groenlandica) meat

Food Chemistry, 1993
Abstract The composition of nonprotein nitrogen (NPN) compounds in manually deboned or mechanically separated seal meat (MSSM) unwashed, or washed, was studied. The NPN contents in manually or mechanically separated meat were 172 and 342 mg %, respectively.

Levels of organochlorine and polycyclic aromatic compounds in harp seal beaters (Phoca groenlandica)

Science of The Total Environment, 1998
Chlorinated dibenzo-p-dioxins, dibenzofurans, chlorobiphenyls, organochlorine pesticides and polycyclic aromatic hydrocarbons were measured in blubber, liver, kidney and muscle of five male and five female, 8-month-old harp seals (Phoca groenlandica).

Polycyclic aromatic hydrocarbons in harp seals (Phoca groenlandica) from the Northwest Atlantic

Archives of Environmental Contamination and Toxicology, 1991
There is virtually no information available on concentrations of polycyclic aromatic hydrocarbons (PAH) in seals from any of the world's oceans. The largest harp seal population in the world is found in Canadian waters of the Northwest Atlantic. Samples of muscle tissue obtained from twenty eight harp seals ranging in age from foetuses to animals 22 ...

Seasonal Distribution Of Harp Seals, Phoca Groenlandica, In The Northwest Atlantic

1997
No abstracts are to be cited without prior reference to the author.Our understanding of the seasonal distribution and migratory behaviour of harp seals is based primarily on surveys of whelping and moulting concentrations, catch data, tag returns and anecdotal observations which may be biased by the location of the observer.

Effects of experimental vitamin E deprivation in the harp seal, Phoca groenlandica

Canadian Journal of Zoology, 1978
Captive harp seals, Phoca groenlandica, were fed a diet of herring with no vitamin E supplement for 18 months and were examined for abnormalities which might be attributable to a lack of the vitamin. Vitamin deficiency was based on clinical, physiological, and biochemical parameters.

Behavioral Reproductive Effort of Nursing Harp Seals, Phoca groenlandica

Journal of Mammalogy, 1987
The behavior of harp seal mother-pup pairs was examined during the nursing periods from 1976 to 1982. Quantitative behavioral data (1978–1982) indicated that behavioral reproductive effort did not vary with maternal age. In all maternal age groups, most births occurred on 2 days in early March.

Ventilation and gas exchange in unrestrained harp seals (Phoca groenlandica)

Comparative Biochemistry and Physiology Part A: Physiology, 1981
Abstract 1. 1. Unrestrained adult harp seals (Phoca groenlandica) spent 87.7 ± 2.2% ( x ± SD) of the time diving and the mean dive time was 278.0 ± 35.3 SD. 2. 2. The mean metabolic rate was 3.24 ± 0.69ml O2·kg−1·min−1 3. 3. The minute ventilation during the surface periods was 62.45 ± 7.32 l·min−1 and the oxygen extraction was 7 ...

Energetics of lactation in harp seals (Phoca groenlandica) from the gulf of St. Lawrence, Canada

Journal of Comparative Physiology B, 1996
This study reports the findings of an integrated, comprehensive analysis of lactation energetics in harp seals conducted using longitudinal measurements of mass, body composition and milk composition from mother-pup pairs in conjunction with water flux measurements in pups.

Ecology of harp seal (Phoca groenlandica) pups on ices in the White Sea

Doklady Biological Sciences, 2009
The harp seal ( Phoca groenlandica ) is the most abundant species of the true seals inhabiting the northern hemisphere. Depending on breeding area location, three populations (Newfoundland, White-Sea, and Jan Mayen) of harp seals are distinguished [1, 2].

DIGESTIBILITY OF CRUSTACEANS and CAPELIN IN HARP SEALS (PHOCA GROENLANDICA)

Marine Mammal Science, 1994
AbstractGross energy intake (GEI), apparent digestible efficiency (%DE), and body‐mass change were studied both in recently weaned and in subadult harp seals fed capelin (Mallotus villosus) and crustaceans (Parathemisto libellula and Thysanoessa sp.) ad lib.
