The Loch Leven Trout (Salmo levenensis). 



The first Loch Leven trout hatched at Northville were produced in 

 the spring of 1883. The species has proved hardy and well adapted for 

 pond culture. 



Further particulars may be learned from the account of the Michigan 

 stations. 



48,000 eggs were received, January 12, 1887, from Sir James G. Mait- 

 land, Howietoun, Scotland. 



The Salbling (Salvelinus alpinus'). 



25,000 eggs of the salbling were received at Cold Spring Harbor dur- 

 ing January and March of 1888 from Herr von dem Borne. Some of 

 these were shipped to the New Hampshire Commission, some to the 

 New York Commission, and the balance were sent to Northville, Mich- 

 igan. 



February 9, 1887, there were received from Herr Max von dem Borne 

 20,000 eggs, of which 8,000 were dead. March 9, 1887, 20,000 eggs 

 were obtained from the same source; of these 5,500 were dead. On the 

 same date 20,000 eggs were received from Herr von Behr. 



The Brook Trout (Salrclimts fontinalis). 



This species is reared at Northville, where the work has been very 

 successful, as will be seen by referring to the account of the Michigan 

 stations. 



The season's work on brook trout outranks any previous season in 

 the percentage of good eggs from a given number. The eggs were 

 taken from October 13 to November 12. 



The highest number of eggs taken from one female was 1,200, and 

 the average number from 786 females was 348 eggs. This species is 

 reared also at Wytheville. The first eggs obtained from the species at 

 this station were secured in October, 1887. The distribution of year- 

 lings from this station in 1888 very much exceeded that of any previous 

 year, aggregating 10,735. 



January 15, 1887, 10,000 eggs were shipped to the National Fish Cul- 

 tural Association, London, England.
