No. 4 (1920) THE FISHERIES OF THE NILGIRIS 151 



As the only nets procurable were very inferior and of large 

 mesh, any smaller fish could pass through. 



1 consider this stream suited to Salmo.irideus but it would have 

 been much better if the upper reaches had been shaded by jungle. 

 The tropical sun shining on exposed eggs on the spawning beds 

 will destroy the life of the alevin. I therefore propose to remedy 

 this by planting small shrubs in the upper reaches in the most 

 suitable places for fry. 



Report on trout in Parson's Valley stream, dated 291/1 June 1907. 



I netted the upper reaches, 26th June 1907, and some of the 

 deeper pools of this stream to ascertain if there were any young 

 fish. 



In the former I am pleased to report that I got four small 

 rainbow trout about 3-j to 4 inches evidently from last January- 

 February spawning. 



This proves beyond doubt that the trout are now breeding and 

 with the additional new blood I introduced last year they should 

 increase rapidly after the next spawning season. The new blood 

 will also improve and strengthen the future alevins, lessen the risk 

 of interbreeding and firmly establish a healthy breed of trout. 



The river will require careful watching to prevent poaching. 

 Now that the bigger fish can be seen feeding in the shallow and 

 narrow reaches it is a great temptation to the people to catch them. 

 During the dry season when the waters are low this would be an 

 easy matter as they frequent places where they could be caught by 

 the hand. 



It would be advisable after the next spawning season (which 

 should be all over by end of March) to remove the very big fish to 

 some other water. 



The deep pools where these fish are found are most difficult to 

 net. The banks in places are practically undermined with numer- 

 ous holes where the fish take refuge, and the nature of the bottom 

 is rendered so uneven by huge clumps of fallen earth from the sides 

 that the odds are greatly in the fish's favour and against the net. 



Report on Sandy Nalla stream, dated 16th November 1906. 

 Temperature at junction of Municipal stream, at 9-30 a.m., 

 cloudy, 58° Fahr.
