Smolt age and size of Atlantic salmon Salmo salar L. and sea trout Salmo trutta L. in a Norwegian river

open access: yesFauna Norvegica, 1984
This paper gives data on smolt age and length of Atlantic salmon and sea trout in the Orkla river in the period 1979 - 1981. The smolt age of the salmon was significantly higher in 1979 (4.1 years) as opposed to 3.4 and 3.3 years in 1980 and 1981 ...

Recommendations for dietary level of micro-minerals and vitamin D3 to Atlantic salmon (Salmo salar) parr and post-smolt when fed low fish meal diets [PDF]

open access: yesPeerJ, 2019
Atlantic salmon (Salmo salar) feeds have changed drastically in their composition from being predominantly marine-based to plant-based. This has altered the dietary supply and availability of micro-nutrients to Atlantic salmon.

Atlantic Salmon (Salmo salar) Transfer to Seawater by Gradual Salinity Changes Exhibited an Increase in The Intestinal Microbial Abundance and Richness

open access: yesMicroorganisms, 2022
The host’s physiological history and environment determine the microbiome structure. In that sense, the strategy used for the salmon transfer to seawater after parr-smolt transformation may influence the Atlantic salmon’s intestinal microbiota. Therefore,

Early maternal experience shapes offspring performance in the wild [PDF]

open access: yes, 2013
Both the environments experienced by a mother as a juvenile and an adult can affect her investment in offspring. However, the implications of these maternal legacies, both juvenile and adult, for offspring fitness in natural populations are unclear.

Effect of Photoperiod and Transfer Time on Atlantic Salmon Smolt Quality and Growth in Freshwater and Seawater Aquaculture Systems

open access: yesFishes, 2023
Smoltification is a key process in Atlantic salmon aquaculture, given it prepares the fish for a successful transit from fresh to seawater. However, industry players have not yet reached a consensus on the best protocols to produce high-quality smolts ...
