No. 4(1920) THE FISHERIES OF THE NILGIRIS 153 



Report on Avalanche river, dated 24th November 1906. 



Nature of bottom. — Upper reaches, mostly gravel. 



Fish food. — There is a fair amount of fish food in the upper 

 reaches, but it is deficient in mollusca. Lower down near the junc- 

 tion of the Emerald Valley stream, large quantities of mollusca and 

 numerous large larvae are found. 



1 consider this stream should make a first-class trout river. I 

 will transplant a quantity of mollusca from the lower reaches to 

 the side runners in the upper waters. The higher reaches are 

 naturally shaded in places, which is a great advantage. 



The only fish life I could see in the river was the indigenous 

 minnow and stone loach. Water was very clear. 



The temperature in the upper waters is quite suitable for the 

 natural breeding of rainbow trout. 



( Restocking with live fish food. ) 



Avalanche river. 



I proceeded to Avalanche on I Ith February 1907 and visited 

 Mclvor's bund, then the junction of Emerald Valley stream, secur- 

 ing a large quantity of live food (mollusca) which I kept in damp 

 sphagmm moss over night at Avalanche bungalow. 



1 2th February 1907. Took above mollusca to the upper tribu. 

 taries of the Avalanche river and stocked in suitable breeding 

 places.
