The potential of oviduct tags and fine‐scale acoustic telemetry to reveal the timing and location of spawning in Arctic salmonids (Salvelinus spp.)

Journal of Fish Biology, EarlyView.
Abstract Identifying and characterizing spawning locations are paramount for the protection of critical fish habitats but can be challenging, particularly in remote locations. Using the underexplored oviduct‐tagging technique, we aimed to identify the timing and location of spawning for wild Arctic char (Salvelinus alpinus) and lake trout (Salvelinus ...

Acute freshwater CO2 exposure does not impair seawater transfer in three different sizes of Atlantic salmon (Salmo salar) subjected to different photoperiod manipulations

Journal of Fish Biology, EarlyView.
Abstract There is a growing interest in Atlantic salmon (Salmo salar) aquaculture to extend the time fish are reared in freshwater (FW) recirculating aquaculture systems (RAS), producing larger FW salmon that can then be induced to undergo smoltification before transfer into marine net pens for grow‐out and harvest.

Rainbow spanning trees in properly coloured complete graphs [PDF]

arXiv, 2017
In this short note, we study pairwise edge-disjoint rainbow spanning trees in properly edge-coloured complete graphs, where a graph is rainbow if its edges have distinct colours. Brualdi and Hollingsworth conjectured that every $K_n$ properly edge-coloured by $n-1$ colours has $n/2$ edge-disjoint rainbow spanning trees.

Effects of Exercise on Serum Lactate Dehydrogenase Activity of Catchable-Size Hatchery Rainbow Trout, \u3cem\u3eSalmo gairdneri\u3c/em\u3e [PDF]

, 1973
Effects of exercise and the relative condition of exercised fish were viii evaluated for two strains of rainbow trout. Circular tanks fitted with a paddle were used to continuously exercise the fish and a stamina tunnel was used to evaluate the condition

In situ infestation of sea trout Salmo trutta with salmon louse Lepeophtheirus salmonis reveals parasite‐induced behavioral modifications

Journal of Fish Biology, EarlyView.
Abstract In areas with high densities of salmon farming, spillover of the ectoparasitic salmon louse Lepeophtheirus salmonis poses a major threat to wild anadromous salmonids. By combining experimentally salmon louse infestation (mean ± standard deviation = 0.25 ± 0.25 lice g−1 fish) with acoustic telemetry, we studied the behavior of wild first‐time ...

Effects of acoustic telemetry transmitter implantation on survival, growth, resting metabolic rate, and swimming performance in juvenile rainbow trout (Oncorhynchus mykiss) and lake trout (Salvelinus namaycush) [PDF]

, 2018
The objectives of this study were to investigate acoustic tag burden in two juvenile salmonid species; rainbow trout (Oncorhynchus mykiss) and lake trout (Salvelinus namaycush), explore the relationship between metabolic rate and swimming performance in ...

Fast and cost‐efficient species identification of Atlantic salmon (Salmo salar L.), brown trout (Salmo trutta), and their hybrids using a single SNP marker

Journal of Fish Biology, EarlyView.
Abstract A workflow for developing a cost‐ and time‐efficient, single nucleotide polymorphism (SNP)‐based assay for species and hybrid identification is described. In a reference set (n = 46), the developed assay identified individuals of two closely related species, the Atlantic salmon (Salmo salar L., n = 23) and brown trout (Salmo trutta, n = 23 ...

The effect of environmental factors on transepithelial potential in a model Amazonian teleost, the tambaqui (Colossoma macropomum): Implications for sodium balance in harsh environments

Journal of Fish Biology, EarlyView.
Abstract The tambaqui (Colossoma macropomum, G. Cuvier 1818) thrives both in the ion‐poor waters of the Amazon and in commercial aquaculture. In both, environmental conditions can be harsh due to low ion levels, occasional high salt challenges (in aquaculture), low pH, extreme PO2 levels (hypoxia and hyperoxia), high PCO2 levels (hypercapnia), high ...
