Dam It, I’m Stranded: Evaluating Fish Stranding Downstream of Two Hydropeaking Dams in Northern Ontario

River Research and Applications, EarlyView.
ABSTRACT Globally, there has been an increase in the development and use of hydropower to produce energy. Hydropeaking is an operating regime that is used to meet real‐time energy demands; however, daily fluctuations in flows may result in fish becoming stranded.

Systematic literature review identifying bacterial constituents in the core intestinal microbiome of rainbow trout (Oncorhynchus mykiss)

Aquaculture, Fish and Fisheries, 2023
Fish aquaculture has become the fastest growing sector in global food production. Thus, ensuring the sustainability of aquaculture practices is of the utmost importance. Studies in higher vertebrates (i.e.

An investigation on the effects of juvenile rainbow trout (Oncorhynchus mykiss) and brook trout (Salvelinus fontinalis) monoculture and duo-culture farming in freshwater and seawater on growth performance [PDF]

, 2017
The objective of this study was to compare growth performance and feed conversion ratios of rainbow trout (Oncorhynchus mykiss) and brook trout (Salvelinus fontinalis) juveniles in monoculture and duo-culture in freshwater and seawater under aquarium ...

Evaluation of Salmon (Salmo salar) and Rainbow Trout (Oncorhynchus mykiss) pin bones using textural analysis and micro X-ray computational tomography [PDF]

, 2019
Industrially, common problems arise with the deboning pin bone process, where Atlantic Salmon (Salmo salar) and Rainbow Trout (Oncorhynchus mykiss) fillets, post rigor, are subjected to a pulling process to remove the pin bones from the fillet.

Early life exploration behaviour and life‐history loci are colocalized in an adaptive genomic hotspot in Atlantic salmon

Journal of Animal Ecology, EarlyView.
The genetic architecture of phenotypic correlations offers insights into how natural selection operates in the wild. Two functional phenotypes in Atlantic salmon, early life exploration and age‐at‐maturity, are correlated at an adaptive genomic hotspot, but through distinct genetic markers (SNPs), ruling out causality.

Glucosensing capacity of rainbow trout telencephalon

Journal of Neuroendocrinology, 2018
To assess the hypothesis of glucosensing systems present in fish telencephalon, we first demonstrated in rainbow trout, by in situ hybridisation, the presence of glucokinase (GK). Then, we assessed the response of glucosensing markers in rainbow trout telencephalon 6 hours after i.c.v. treatment with glucose or 2‐deoxyglucose (inducing glucoprivation).

Integrating Sr isotopes, microchemistry, and genetics to reconstruct Salmonidae species and life history

Archaeometry, EarlyView.
Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...

Effects of dietary salbutamol on growth and carcass composition in rainbow trout (Oncorhynchus Mykiss) (Walbaum) : a thesis presented in partial fulfillment of the requirements for the degree of Master of Science (Physiology) at Massey University, Palmerston North, New Zealand [PDF]

, 2001
Salbutamol, a β2 adrenergic agonist, has been shown to reduce carcass fat and increase muscle mass and improve feed conversion efficiency in pigs. In the present study, the effects of dietary salbutamol at 20 ppm on growth, feed conversion efficiency ...

FECUNDITY OF RAINBOW TROUT

Ankara Üniversitesi Veteriner Fakültesi Dergisi, 1983
This study has been conducted to find out fecundity of rainbow trout raised at Gip Research station of Fisheries School, Firat University. Thirty four fully matured female trouts of three and lour years of age were used. Estimates of ova were made both volumetrically, gravimetrically and by actual count.
