T52 MADRAS FISHERIES BULLETIN VOL. XII, 



Temperature at noon (opposite Toda Mund), 6o° Fahr. 



at I-30 p.m. highest reach in shade of jungle, 

 58°Fahr. 



Nature of the bottom. — Gravel, sand and mud. 



Animalcules, etc. — There is an abundance of minute life under the 

 stones, immediately above the small tributary on the left going 

 towards the source, three-fourths of a mile from the mouth or junc- 

 tion. Useful fish food was in some places (where the bottom of 

 stream was mud) very scarce. 



Class of food found. — Phryganea, Hydrophilus, numerous larvae 

 of above, indigenous minnow, crabs, etc. 



Remarks. — On the higher reaches after the stream divides into 

 three runners, there is on the main source an Irish bridge, which 

 might prevent big fish descending from the spawning ground after 

 the flood water had subsided below the level of stones. An open- 

 ing could be made to allow the passage of fish. This is a small 

 stream and not very suitable for trout as in the dry season the 

 upper waters will be very shallow. If trout were introduced they 

 would descend to the Municipal stream in dry weather. 



Report on Municipal stream, dated 17th November 1906. 



Temperature taken at ford below toll, bar on Pykara 



road at 9-45 a.m., bright sun 59*Fahr. 



Temperature of side runner on right hand bank 



going down stream, IO-30 a.m. ■■• •■• ... 58 »> 



Nature of bottom.—Mud, gravel, sand, covered in places with 

 coarse weed. 



Remarks. — This stream is very foul and dirty. In places weeds 

 should be removed and an attempt made to introduce mollusca and 

 other fish food into the lower reaches below the toll-bar which is 

 at present deficient therein. The stream enters a thick shola and 

 descends with a succession of small falls interspersed with good 

 pools. Fish could pass down to these pools but not ascend again. 



I consider that, in its present dirty condition, it is not very 

 suitable for trout.
