What have we found!?
 
-75 fish total of which 35 were eels ( 3 not analysed for weight/length).
 
-Currently 8 other species including mört, braxen, abborre, benlöja, gös, lake, suttare och björkna.  
 
-Biggest eel 1.64kg / 987mm on 22 May.
 
Total eel numbers with different trap treatment:
 
Ytan bara: –>2 stk ( +3stk non analysed)
 
Botten bara: –>11 stk
 
Ytan+botten:  Ytan –> 3stk
                     Botten –> 16stk
 
 
So for the month of May, we have a total of 27 eels in bottom trap and 5 in Ytan. The most likely scenario to catch eels when both top and bottom are open, and then the bottom trap is most productive.
 
However this statistic could easily change within a matter of days since the difference is so minimal!


I have also taken a couple of other pictures of the nature at Alsterälven. The first picture is of a newly emerged dragonfly, clinging onto some vegetation in preparation to dry its wings in the sun to enter adulthood.

Just above is a another sun basker – a snok which has settled just above my upstream migration trap!
