Water velocity shapes juvenile salmonids
Phenotypic plasticity in morphology is often considered adaptive. Stream-living fish encounter considerable spatial and temporal environmental variation in their native habitats, and the ability toExpand

Genetic lineages and postglacial colonization of grayling (Thymallus thymallus, Salmonidae) in Europe, as revealed by mitochondrial DNA analyses
In stark contrast to other species within the Salmonidae family, phylogeographic information on European grayling, Thymallus thymallus, is virtually nonexistent. In this paper, we utilizedExpand

Composition of the milt of some teleost fishes
The milt composition of six freshwater teleosts was studied, and the measured parameters showed clear specific differences between species. The highest spermatocrits and sperm densities were observedExpand

Anaerobic wintering of crucian carp (Carassius carassius L.). I: Annual dynamics of glycogen reserves in nature
Abstract 1. 1. Seasonal variation in liver size (2–15% of total weight) as well as in liver and muscle glycogen content (2%–35% and 0.5–4%, respectively) of crucian carp were shown to be prominent inExpand

Genetic assessment of spatiotemporal evolutionary relationships and stocking effects in grayling (Thymallus thymallus, Salmonidae)
Domestically reared introduced (or escaped) individuals can have detrimental genetic effects on the indigenous populations into which they are released. Consequently, numerous studies have attemptedExpand

Variation in the properties of milt from the Finnish landlocked salmon (Salmo salar m. sebago Girard) during a spawning season
Abstract Properties of milt and the chemical composition of the seminal plasma from landlocked salmon ( Salmo salar m. sebago Girard) were studied in the course of a spawning season. Milt samplesExpand

Variation in aggressive behaviour and growth rate between populations and migratory forms in the brown trout, Salmo trutta
Aggressiveness of juvenile salmonid populations has been suggested to correlate positively with the time the fish spend in the stream. Consequently, resident populations are expected to be moreExpand

A note on seasonality in anoxia tolerance of crucian carp (Carassius carassius (L.)) in the laboratory
The year of the crucian carp can be divided into three periods. 1) the reproductive period in spring and early summer. This starts from the melting of the ice (in April —May) and during its firstExpand

Metabolic rate and aggressiveness between Brown Trout populations
Summary 1. Studies focusing on the physiological variation between populations and its connection to fitness-related traits are rare, even though integrating these fields would increase knowledge onExpand

Microsatellite Analysis of Hatchery Stocks and Natural Populations of Arctic Charr, Salvelinus Alpinus, from the Nordic Region: Implications for Conservation
Semi-automated fluorescent genotyping of eight polymorphic microsatellite loci was used to assess the level of genetic diversity and population differentiation in Nordic stocks of non-anadromousExpand
