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

Alternative Mating Strategies in Atlantic Salmon and Brown Trout [PDF]

Journal of Heredity, 2001
By screening variable number of tandem repeat (VNTR) loci, multiple paternity within clutches has been found in wild populations of southern European Atlantic salmon (Salmo salar) and brown trout (Salmo trutta). For Atlantic salmon, we determined the relative contribution of alternative male phenotypes to the next generation.

Mesohabitat Use by Brown Trout (Salmo trutta) in a Small Groundwater-dominated Stream

, 2010
Groundwater-dominated streams have particular flow regimes that commonly support populations of trout. Meso- and micro-habitat surveys were carried out on a reach of the river Tern that drains a Triassic sandstone aquifer in the English West Midlands, to

Linking Flow Regime Metrics to Spawning Migration Behavior of Threatened Green Sturgeon: Implications for Water Management in Regulated Rivers

River Research and Applications, EarlyView.
ABSTRACT Flow regime alteration is among the most pervasive threats to freshwater ecosystems globally, and migratory species are particularly vulnerable to these impacts. Despite this, specific aspects of flow regimes that shape spawning migrations remain poorly understood for most threatened species.

Banking Biodiversity: Ex Vivo Solutions for a Planet in Crisis

Zoo Biology, EarlyView.
Genetic diversity is being lost faster than it can be cataloged. Biobanking preserves cells, gametes, and DNA as recoverable material for future conservation use, and delivers most when collections are established proactively rather than deployed once populations are already critically depleted.

Water temperature and river discharge drive age-dependent changes in brown trout (Salmo trutta) growth. [PDF]

J Fish Biol
Abstract Rivers and streams exhibit inherent variability in environmental conditions, particularly in water temperature and stream discharge. These factors can impact fish growth through both direct (i.e., physiological) and indirect (i.e., ecosystem productivity) mechanisms.

Life history attributes influencing metabolic variation in an estuarine fish

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Considering that energy availability and oxygen transport potential are limited in supplying metabolic requirements, all animals face trade‐offs between competing metabolic demands.

Gonadal Development–Related Genes and a Male‐Specific Genetic Marker Identified in the Endangered Sichuan Taimen (Hucho bleekeri)

Integrative Zoology, EarlyView.
Integrated transcriptomic and proteomic analyses were used to validate gonadal development–related genes and to identify a sex‐specific molecular marker in Hucho bleekeri. ABSTRACT Sex determination and differentiation represent fundamental topics in reproductive biology. Sichuan taimen (Hucho bleekeri), a first‐class national protected fish species in

Meat Quality of Rainbow Trout (Oncorhynchus mykiss) and Brown Trout (Salmo trutta fario) Farmed in Bulgaria

Journal of Food Quality and Hazards Control, 2019
Background: Fish meat is outlined with high nutritional value having essential amino acids, unsaturated fatty acids, mineral and vitamins. In this short report, we compared the meat quality of rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo ...
