Alternative Life-History in Native Trout (Salmo spp.) Suppresses the Invasive Effect of Alien Trout Strains Introduced Into Streams in the Western Part of the Balkans

Frontiers in Ecology and Evolution, 2020
The diversity of native trout fish Salmo spp. comprises a variety of nominal taxa in Serbia, Montenegro, and Bosnia and Herzegovina. Recent mapping of the resident trout populations detected the presence of brown trout Salmo trutta (sensu stricto) of the

Does individual variation in metabolic phenotype predict fish behaviour and performance? [PDF]

, 2015
There is increasing interest in documenting and explaining the existence of marked intraspecific variation in metabolic rate in animals, with fishes providing some of the best-studied examples.

Morphometric and External Injury Characterization of Rainbow Trout (O. mykiss) Used for Stocking in the Alpine River Inn (Bavaria, Germany)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

Host Switching of Zoonotic Broad Fish Tapeworm (Dibothriocephalus latus) to Salmonids, Patagonia [PDF]

, 2019
Diphyllobothriosis is a reemerging zoonotic disease because of global trade and increased popularity of eating raw fish. We present molecular evidence of host switching of a human-infecting broad fish tapeworm, Dibothriocephalus latus, and use of ...

Effects of the Invasive Round Goby on Swedish Recreational Fishing Values

Fisheries Management and Ecology, EarlyView.
ABSTRACT The round goby, an invasive fish from the Black and Caspian Seas, has spread to Swedish waters, threatening recreational fisheries. We modeled impacts on the future recreational fishery in Sweden using data from a recreational fishing survey, and estimated effects of the round goby on other fish species. Values attached to recreational fishing

Differential effects of food availability on minimum and maximum rates of metabolism [PDF]

, 2016
Metabolic rates reflect the energetic cost of living but exhibit remarkable variation among conspecifics, partly as a result of the constraints imposed by environmental conditions.

Impact of Environmental Conditions on the Spawning Migration of Sea Trout (Salmo trutta L.) in Two Large, Sub‐Arctic River Systems

Fisheries Management and Ecology, EarlyView.
ABSTRACT The global decline in salmonid stocks has increased the need for knowledge of local adaptations and life history strategies of salmonids. In this study, we used radio‐telemetry tracking data from sea trout populations in two large high‐latitude rivers to model upstream spawning migration speed of trout in response to prevailing environmental ...

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

Fisheries Management and Ecology, EarlyView.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Epidermal growth factor receptor expression in mice skin upon ultraviolet B exposure - Seborrheic Keratosis as a coincidental and unique finding

Advanced Biomedical Research, 2012
Background: Ultraviolet B (UVB) is the most damaging component of sunlight. It rapidly activates the epidermal growth factor receptor (EGFR) and generates reactive oxygen species (ROS) in excessive quantities that quickly overwhelm tissue antioxidants.
