BIOCHEMICAL AND MORPHOMETRIC PARAMETERS OF PRE-LARVAE OF THREE SALMONIDS SPECIES AT ONE-DAY AGE

open access: yesRibogospodarsʹka Nauka Ukraïni, 2016
Purpose. To study and analyze the morphometric and some biochemical parameters of pre-larval brown trout, rainbow trout and brook trout in post-embryonic period under the conditions of "Rybnyi Potik” farm in the Transcarpathian region for further use of ...

Ontogenetic and spatial variations in brown trout habitat selection [PDF]

open access: yes, 2010
Habitat quality and quantity determine many biological processes and traits that directly affect the population dynamics of stream fishes. Understanding how habitat selection is adjusted to different ecological conditions is essential to improve ...

Modelling brown trout spatial requirements through physical habitat simulations [PDF]

open access: yes, 2010
Territorial behaviour is often considered the main mechanism regulating salmonid populations and territory size regarded as the proximate factor that limits abundance, being mainly determined by body size. Despite the spatial requirements of young‐of‐the‐

Effects of introduced trout predation on non-diadromous galaxiid fish populations across invaded riverscapes [PDF]

open access: yes, 2013
We assessed the landscape-scale effect of predation pressure from trout on the population integrity and distributions of non-diadromous galaxiids in high-country streams of the South Island, New Zealand.

Individual variation in behaviour: personality and performance of brown trout in the wild [PDF]

open access: yes, 2010
Individuals from the same population often show very different behaviour. These differences, when consistent across time, are referred to as animal personality or behavioural syndromes. Explaining the occurrence of animal personality from an evolutionary

Sex-specific effects of inbreeding in juvenile brown trout

open access: yesMolecular Ecology, 2023
Inbreeding depression, i.e., the reduction of health and vigour in individuals with high inbreeding coefficients, is expected to increase with environmental, social, or physiological stress. Differences in the strength of sexual selection are therefore predicted to usually lead to higher inbreeding depression in males than in females.

Sensitivity of brown trout reproduction to long-term estrogenic exposure [PDF]

open access: yes, 2008
A decline in brown trout (Salmo trutta fario) catches has been reported in Switzerland, but at present the causative factors have not been clearly identified.

Food resources and trophic relationships of brown, rainbow trout and european grayling in different habitats of Shypit river of the Transcarpathian region

open access: yesRibogospodarsʹka Nauka Ukraïni, 2016
Purpose. To study food resources, feeding conditions and trophic relationships of the brown trout (Salmo trutta morpha fario), rainbow trout (Oncorhynchus mykiss), and European grayling (Thymallus thymallus) in a Transcarpatioan river.

Proliferative kidney disease in brown trout – infection level, pathology and mortality under field conditions [PDF]

open access: yes, 2015
Proliferative kidney disease (PKD) is an emerging disease threatening wild salmonid populations. In temperature-controlled aquaria, PKD can cause mortality rates of up to 85% in rainbow trout.
