Efficiency of Portable Antennas for Detecting Passive Integrated Transponder Tags in Stream-Dwelling Salmonids. [PDF]

open access: yesPLoS ONE, 2016
Portable antennas have become an increasingly common technique for tracking fish marked with passive integrated transponder (PIT) tags. We used logistic regression to evaluate how species, fish length, and physical habitat characteristics influence ...

Seasonal changes in abundance of brown trout (Salmo trutta) and rainbow trout (s. gairdnerii) assessed by drift diving in the Rangitikei river, New Zealand [PDF]

open access: yes, 1985
Numbers and approximate sizes of brown trout (Salmo trutta L.) and rainbow trout (5. gairdnerii Richardson) were estimated by snorkel divers at 6 sites in the middle reaches of the Rangitikei River, North Island, New Zealand, over 14 months.

Water quality indicators in high-density cage farming of trout [PDF]

open access: yesBIO Web of Conferences, 2023
Trout fishing means raising fish in water whose temperature does not exceed +18°C under completely or partially artificial conditions. Today, several fish belonging to the salmon family are bred in cold water fisheries in the world. These are river trout

Competition Within and Between Year Classes in Brown Trout; Implications of Habitat Complexity on Habitat Use and Fitness [PDF]

open access: yes, 2017
Habitat use and fitness are restricted and altered by both intra‐ and interspecific competition over limited resources. As a result, population dynamics may be affected both by cohort structure, habitat complexity and habitat availability.

Feeding Habits and Diet Overlap between Brown Trout Lineages from the Danube Basin of Croatia

open access: yesFishes, 2022
Brown trout of non-native lineages have been stocked into Croatian streams and rivers primarily to meet angler demand. The diet of brown trout in the Black Sea Basin of Croatia is poorly understood, and there are no studies examining feeding competition ...

Diversity of brown trout, Salmo trutta (Actinopterygii: Salmoniformes: Salmonidae), in the Danube River basin of Croatia revealed by mitochondrial DNA [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2020
Background. The molecular diversity of brown trout, Salmo trutta Linnaeus, 1758, has been poorly studied in Croatia. The control region of mitochondrial DNA (CR mtDNA) is in addition to other molecular markers a reliable for identifying phylogenetic ...

The impact of fine sediments in small rivers : method development and effects on brown trout redds [PDF]

open access: yes, 2013
Native brown trout populations are declining in Swiss rivers. This could be due, among other reasons, to a clogged riverbed caused by fine sediment deposition, leading to a decrease in interstitial flow and therefore in a reduced oxygen supply to the ...

Diet of rainbow trout in Lake Rotoiti: an energetic perspective [PDF]

open access: yes, 2012
We characterised seasonal and ontogenetic changes in diet and prey energy density of rainbow trout (Oncorhynchus mykiss) in Lake Rotoiti, New Zealand, to better understand the prey requirements of trout in central North Island lakes.
