50 Osc. 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. Trybom mentions that elvers 10 — 15 

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

 of Sweden, the northermost place being the river Ume.^) Try- 

 bom 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 farther 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.
