50 Ose. Nordqvist, Some observations about the eel in Finland. 



With those opinions coincide the observations made by 

 German naturalists, that the adult eel migrates along the Ger- 

 man coast of the Baltic from the east to the west^) and that 

 the male-eels are becoming scarcer in the eastern parts of the 

 Baltic. 2) 



On the other side F. T ry bom mentions that elvers 10 — 15 

 cm long have been found in different rivers on the east-coast 

 of Sv^'eden, the northermost place being the river Ume.^) Try- 

 b o m also states the occurrence of male-eels on the east-coast of 

 Sweden in Kalmar län. From those observations he makes the 

 conclusion that the eel does probably spawn in the southern 

 part of the Baltic. Still f arther goes Arthur Feddersen who 

 believes that the eel does spawn in fresh water. ^) 



Those contrary opinions have induced me to examine 

 eels from the Finland-waters. Till now I have examined 134 

 eels, of which 



91 were taken in lamprey-pots in the river Kumo at Lam- 

 mais, about 30 kilometers from the sea; 



36 in the same river also in lamprey-pots at Saksankorva, 

 about 23 km from the sea; and 



7 in the sea on the south-coast of Finland upon long-lines. 



All of them were taken in the months of August and 

 September 1902.
