Seasonal changes of liver glycogen content and condition factor of wild Atlantic salmon parr in a sub‐arctic river

Abstract – Mean liver glycogen content of 1–4‐year‐old Atlantic salmon parr varied from 0.5 to 9.5% (of fresh liver mass) and condition factor (CF) from 0.66 to 0.85 in the sub‐arctic River Teno system in northern Finland during 2 years of study. There were no significant differences in liver glycog...

Description
Summary:Abstract – Mean liver glycogen content of 1–4‐year‐old Atlantic salmon parr varied from 0.5 to 9.5% (of fresh liver mass) and condition factor (CF) from 0.66 to 0.85 in the sub‐arctic River Teno system in northern Finland during 2 years of study. There were no significant differences in liver glycogen contents of different age groups as there were in CF. However, there were seasonal differences in liver glycogen content and CF of the wild parr. The lowest liver glycogen contents were observed in July and the highest in September and December whereas the lowest CFs were observed in May and the highest in July.
