Salmonid alphavirus (SAV) [PDF]

Journal of Veterinary Research, 2018
Abstract Salmonid alphavirus (SAV), genus Alphavirus, family Togaviridae, is a single-stranded RNA virus affecting Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss). It is known to be responsible for pancreas disease (PD) and sleeping disease (SD) which are increasing problems, causing high fish mortality and economic

Species‐ and origin‐specific susceptibility to bird predation among juvenile salmonids

Ecosphere, 2023
Juvenile salmonids often experience high mortality rates during migration and bird predation is a common source of mortality. Research suggests that hatchery‐reared salmonids are more prone to predation than wild salmonids, and that Atlantic salmon ...

Alternative life‐history strategy contributions to effective population size in a naturally spawning salmon population

Evolutionary Applications, 2023
Alternative life‐history tactics are predicted to affect within‐population genetic processes but have received little attention. For example, the impact of precocious males on effective population size (Ne) has not been quantified directly in Pacific ...

OSTEOLOGICAL CHARACTERIZATION OF FOUR SPECIES OF THE GENERA GOBIO AND ROMANOGOBIO WITH SOME REMARKS TO THE STATUS OF THE FORMER SUBGENUS RHEOGOBIO

Ribogospodarsʹka Nauka Ukraïni, 2014
Purpose. The aim of this work is to clarify the matter of suitability of current Gobioninae systematics, where Rheogobio is used as a synonym of Romanogobio or as a separate taxon by comparing four species of the genera Gobio and Romanogobio on the basis
