Cytological studies in the smelt (Osmerus eperlanus L.)

open access: yesHereditas, 2009
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.

Invasive Species Appearance and Climate Change Correspond with Dramatic Regime Shift in Thermal Guild Composition of Lake Huron Beach Fish Assemblages

open access: yesFishes, 2022
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.

Food composition and zooplankton selection by smelts, Osmerus eperlanus L., in Lake Tyrifjorden, Norway

open access: yesFauna Norvegica, 1983
Stomach analyses were carried out on 80 - 160 mm long smelts sampled monthly from May 1976 to September 1977. The amount of food was lower from February to April than during the rest of the year.

Glycerol synthesis in the rainbow smelt Osmerus mordax [PDF]

open access: yesJournal of Experimental Biology, 1995
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.
