Abstract:
... The influence of three common stocking practices for two strains (Ätran and Burrishoole) of hatchery-reared Atlantic salmon, Salmo salar, on smolt size, migration probability and migration timing were investigated in situ. Using a common garden experiment, fish from these populations were released as fry, half-year olds and one-year olds. Our results indicate that fish released at the fry and half ...

Abstract:
... The costs and benefits of a particular behavioural trait, such as boldness or aggression, may vary depending on the physical environment. We tested whether the common practice of adding physical structure (i.e. boulders) to streams to increase salmonid density has behavioural consequences, as open habitats are predicted to favour individuals that are more bold and aggressive. Wild young-of-the-yea ...

Abstract:
... By impeding migration and degrading habitat downstream, dam construction has caused population declines in many migratory fish populations. As part of the landlocked Atlantic salmon (Salmo salar) restoration program in Lake Champlain, the Willsboro Dam was removed from the Boquet River, NY in 2015 providing an opportunity to study the effects of dam removal on spawning habitat quality and availabi ...

Abstract:
... Statistics GST′ and Jost's D have been proposed for replacing FST as measures of genetic differentiation. A principal argument in favour of these statistics is the independence of their maximal values with respect to the subpopulation heterozygosity HS, a property not shared by FST. Nevertheless, it has been unclear if these alternative differentiation measures are constrained by other aspects of ...

Abstract:
... Random samples of individual fish for the cause of estimating body size average and variation in fish groups is a widespread practice in scientific experiment as well as in fish production. Sample accuracy and precision naturally increases with sample size, but may very well depend on other factors such as fish size dependent success rate of capture method and spatial-behavioural size segregation. ...

Abstract:
... Farming Atlantic salmon (Salmo salar L) in submerged cages may be a way for the industry to avoid surface related problems such as salmon lice and make new farming sites available. However, salmon do not cope with long term submergence and regularly need to access the surface to refill their swim-bladders and maintain buoyancy. We tested how salmon coped with submerged cages that were lifted to th ...

Abstract:
... Diadromous fish populations are strongly affected by in-stream barriers that cause river network fragmentation, constraining productivity or preventing completion of their lifecycle. Removal or reduction of barrier impacts is a restoration measure associated with unambiguous benefits. Management of barriers is therefore often prioritised above other restoration actions. Barrier management is prior ...

However, the impact of navigation locks on downstream migrating fish is rarely documented. In Belgium, the Albert Canal connecting the Meuse River to the Scheldt Estuary may offer migration opportunities for European eel (Anguilla anguilla) and Atlantic salmon (Salm ...

Subsequent to the PD outbreak, large a ...
