NON-MIGRATORY TROUT. 



It is among the non-migratoiy SalmunidcB that we may 

 expect, and, in fact, have already gained, the greatest 

 success. 



GKEAT LAKE TROUT. 



In the great lakes of Switzerland, especially Neuchatel 

 and Geneva, there exists that splendid fish, the Great 

 Lake Trout. For many years past I have yearly re- 

 ceived some splendid eggs of the Great Lake trout from 

 the late Dr. Vouga." 



These Great Lake trout, when the spawning time 

 arrives, are compelled to run up the tributaries to lay 

 their eggs. At this time they are caught by those who 

 have permission from the Government authorities ; the 

 eggs are taken from them, and a certain proportion of 

 the young turned back into the lake. I have a very 

 high opinion of these Great Lake trout. Both as eggs 

 and fry they are very hardy, and they are most suitable 

 to turn down into lakes where, of course, there are no 

 pike. 



More especially are they suitable for large pieces of 

 water, such as reservoirs which supply towns, &c. At 

 the request of Mr. Alderman Smith, of Manchester, I 

 turned down a large number of these fish in Thirlmere 

 Lake, where in future years they will doubtless afford 

 excellent angling to tourists and the Manchester people. 



Every year I grow a new generation of these fish at 

 my Museum of Economic Fish Culture, South Ken- 

 sington. Specimens in the tanks have become very 

 tame, and I have grown them up to the heavy weight 



* Dr. Vouga was Professor of Natural History at Neuchatel. He 

 was one of the most learned pisciculturists I ever met. I regret 

 much to say he lately died of heart disease.
