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.

Comparing climate change and species invasions as drivers of coldwater fish population extirpations. [PDF]

open access: yesPLoS ONE, 2011
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 ...

Assessments at multiple levels of biological organization allow for an integrative determination of physiological tolerances to turbidity in an endangered fish species. [PDF]

open access: yes, 2016
Turbidity can influence trophic levels by altering species composition and can potentially affect fish feeding strategies and predator-prey interactions.

Fonctionnement d'une population d'éperlan (Osmerus eperlanus, Osmériformes Osmeridae) située en limite méridionale de son aire de répartition, influence de la température

open access: yesKnowledge and Management of Aquatic Ecosystems, 1998
Ce travail présente le fonctionnement de la population d'éperlan Osmerus eperlanus dans le bassin versant de la Gironde entre 1979 et 1996 et examine les liens possibles avec la température.

Rainbow Smelt (Osmerus mordax) Genomic Library and EST Resources

open access: yesMarine Biotechnology, 2008
AbstractGenomic resources in rainbow smelt (Osmerus mordax) enable us to examine the genome duplication process in salmonids and test hypotheses relating to the fate of duplicated genes. They further enable us to pursue physiological and ecological studies in smelt.

ASIATIC SMELT OSMERUS DENTEX STEINDACHNER ET KNER, 1870 OF THE UDA RIVER (NORTHWESTERN OKHOTSK SEA) — BIOLOGY, ECOLOGY, FISHERY

open access: yesИзвестия ТИНРО, 2019
Data on biology, ecology and fishery of asiatic smelt in the Uda River during its spawning migration are analyzed. The spawning begins in May-June in 2–11 km from the river mouth and lasts 3–10 days. Timing of its start varies from May 22 (2014 and 2018)

Fish predation pressure on zooplankton in a large northern temperate lake: impact of adult predators versus juvenile predators; pp. 356–367 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2018
In recent decades, a marked decrease in planktivorous fish (Osmerus eperlanus eperlanus m. spirinchus Pallas and Coregonus albula (L.)) in Lake Peipsi has stimulated research into the potential effect of fish predation on zooplankton.

Length–weight relationships of 12 fish species (Actinopterygii) from nearshore and coastal Alaskan waters of the eastern Bering, Chukchi, and Beaufort seas [PDF]

open access: yesActa Ichthyologica et Piscatoria
Changing ocean conditions in higher latitude ecosystems and the potential impact on marine fish underscores the need for baseline information on their biology and growth.

Untersuchungen zur chemischen Zusammensetzung und Nematodenbelastung von Stinten (Osmerus eperlanus L.) [PDF]

open access: yes, 2006
Smelt (Osmerus eperlanus L.) from the river Elbe has a long tradition as local food speciality. It is offered baked or fried every year during spring in many restaurants along the river.

Lipid correction of hydrogen stable isotope ratios in fish

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Lipids are known to affect stable isotope ratio of organisms, especially δ13C values, and simple arithmetic lipid‐correction procedures have been developed based on the carbon to nitrogen ratio (C : N) that is a proxy for lipid content. Equivalent issues will likely arise with the increasing use of hydrogen isotopes in ecology, but as yet no ...
