Developing nondestructive techniques for managing conflicts between fisheries and double‐crested cormorant colonies

open access: yesWildlife Society Bulletin, 2015
Double‐crested cormorants (Phalacrocorax auritus) have been identified as the source of significant mortality to juvenile salmonids (Oncorhynchus spp.) in the Columbia River Basin.

Salmonid Jumping and Playing: Potential Cultural and Welfare Implications

open access: yesAnimals, 2017
Salmonids of several species and other fishes can jump into the air from the water. This behavior has been used in net pen culture applications to control parasitic sea lice. The reasons that salmonids jump remain a topic for speculation.

Towards sustainable and ocean-friendly aquafeeds: Evaluating a fish-free feed for rainbow trout ('Oncorhynchus mykiss') using three marine microalgae species

open access: yesElementa: Science of the Anthropocene, 2020
Aquaculture, the fastest growing food sector, is expected to expand to produce an additional 30 million metric tons of fish by 2030, thus filling the gap in supplies of seafood for humans.

The Role of Cold-Water Thermal Refuges for Stream Salmonids in a Changing Climate—Experiences from Atlantic Canada

open access: yesFishes, 2023
Thermal refuges are becoming increasingly influential for dictating the population status and spatial distribution of cold-water stenotherm salmonids in the mid- to southern extent of their range.

A Tool for Prioritizing Gravel Augmentation Reaches for Sediment Starved Rivers

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Gravel augmentation is a widely used restoration technique used to improve habitat below dams, including salmonids spawning habitat. However, gravel augmentation can be cost‐prohibitive, and it is often unclear which stream segments have the highest potential to benefit spawning salmonids.

Chilean Salmon Sushi: Genetics Reveals Product Mislabeling and a Lack of Reliable Information at the Point of Sale

open access: yesFoods, 2020
Species diagnosis is essential to assess the level of mislabeling or misnamed seafood products such as sushi. In Chile, sushi typically includes salmon as the main ingredient, but species used are rarely declared on the menu.

Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

ВЪЗМОЖНОСТИ ЗА МЕЖДУВИДОВА ХИБРИДИЗАЦИЯ ПРИ ПЪСТЪРВОВИ РИБИ ЧРЕЗ МЕТОДИТЕ НА АСИСТИРАНА РЕПРОДУКЦИЯ

open access: yesЖивотновъдни науки, 2014
Opportunities for interspecific hybridization in salmonids were discussed. Here we review the literature on interspecific interactions of brown trout with brook trout and Atlantic salmon to assess the potential effects of introduced brook trout on ...

Hunting and fishing harvest data collection: a horizon scanning exercise from the French context

open access: yesWildlife Biology, EarlyView.
Legal and societal moves increasingly lead leisure hunting and fishing practitioners to record their harvest. The total number of individuals harvested per population per year is the minimum required information to feed into demographic models and allow science‐based management. Some few schemes record more detailed data, hence allowing better‐informed

Abiotic variables drive different aspects of fish community trait variation and species richness across the continental United States

open access: yesJournal of Animal Ecology, EarlyView.
Trait distributions provide insight into how niches overlap within a broader trait space. By integrating individual‐level trait observations from different communities, we can explore how facets of trait dimensionality vary across environmental conditions.
