Age, growth and food of the Burbot Lota lota in two eutrophic lakes in southeast
The growth and food of the burbot Lota lota was studied in two neighbouring meso-eutrophic lakes in southeast Norway. The burbot grew slower and reached smaller theoretical maximum lengths in Lake Øgderen than in Lake Rødenes (L∞ = 40.5 cm vs 69.5 cm ...

Genetic structure of sugar kelp in the St. Lawrence Estuary and Gulf (Québec, Canada). [PDF]
Abstract The sugar kelp, Saccharina latissima, is cultivated at low scale in Quebec, Canada, and current practice involves seeding meiospores or gametophyte stocks onto spools carrying twine and transferring these to a seaweed farm site. As the stocks can originate from locations spanning several hundreds of kilometers from the farm sites, such ...

Cytological studies in the smelt (Osmerus eperlanus L.)
The cytology of the smelt, Osmerus eperlanus, has been studied. This salmonid has 2n = 54 with 8 pairs of metacentric and 19 pairs of acrocentric chromosomes, which gives an N. F. value of 70, the lowest value so far observed in the family. At meiosis 27 bivalents are formed, most of which are rod-shaped.

Lake Huron has undergone dramatic and well-documented lake-wide food web changes as a result of non-native species introductions. Coastal beaches, which serve as nursery habitats for native and introduced species, are, however, relatively poorly studied.

Comparing climate change and species invasions as drivers of coldwater fish population extirpations. [PDF]
Species are influenced by multiple environmental stressors acting simultaneously. Our objective was to compare the expected effects of climate change and invasion of non-indigenous rainbow smelt (Osmerus mordax) on cisco (Coregonus artedii) population ...

Glycerol synthesis in the rainbow smelt Osmerus mordax [PDF]
ABSTRACT Rainbow smelt, Osmerus mordax, maintain high glycerol levels in winter to avoid freezing. After intramuscular injection of 14C-labeled glucose, [14C]glycerol was found in the blood, liver and muscle, indicating that glycogen is a source of glycerol.
