Besides the above two tanks another tank which holds permanent 

 water, viz., Peddamentrala in Markapur taluk of the Kurnool district 

 was also stocked. 



Barur and Penukondapuram tanks were not stocked during the 

 year under report, but 1 hope will be stocked during the current 

 year. 



14. The Colair Lake project. — As mentioned in my last year's 

 report the submission of detailed estimates called for in G.O. No. 61, 

 Revenue, dated the 6th January 191 3, is still being delayed owing to 

 the existence of stake nets and fixed engines. When my new Assistant 

 is appointed he will be put on this work ; after a thorough investiga- 

 tion, proposals for the removal of these nets under G.O. No, 1905, 

 Revenue, dated 2nd July 1914, will be drawn up and submitted to 

 Government for necessary action. 



15. T]ie Ippur Fish-farm in Nellore. — The site selected is in the 

 bed or Ippur tank about 11 miles from Venkatachalam station on the 

 Madras and Southern Mahratta line. The water is supplied by an 

 open channel from Survapalli tank and the Public Works Depart- 

 ment records show that the water-supply in this tank, if carefully 

 guarded, should not fail to supply the fishery excepting in years of 

 great drought. 



The construction of a well has been provided for and a small 

 pumping plant to insure against the above danger and for other 

 necessary work. 



The fishing rights of this and Puduparti tank adjoining have been 

 handed over to this department and the small rentals amounting to 

 only a few rupees will be paid as compensation to the Nellore District 

 Board. The plans of the fishery and buildings have been perused by 

 the Public Works Department and the works sanctioned by Govern- 

 ment in G.O, No. 2997, dated 14th October 1914. 



The work is now in the hands of the Executive Engineer of Nellore 

 and will be completed this year, 



16. Breeding and distrilnLtion of larvicidal fish. — A 

 good deal of Mr. Wilson's time and energy were spent 

 on this matter ; not only were further experiments con- 

 ducted at Sunkesula, but the new Ippur farm is specially 

 devised to provide a supply of larvicidal fish for distri- 

 bution to municipalities, etc. 



Mr. Wilson reports as follows ; — 



" In July I inspected several wells in Tondiyarpet, Madras, with 

 Captain Hodgson, I. M.S., in connection with the Anti-malarial opera- 

 tions. Many of the wells visited that had been stocked with larvicides, 

 were examined and absolutely devoid of mosquito larvee. 



The danger of the present method of stocking with fish larvicides 

 was pointed out to Captain Hodgson, viz., the liability of intro- 

 ducing eggs of predaceous fish with the larvicides. 



The present system of gathering the small fish from surrounding 

 ponds is an exceedingly bad method and it is almost a certainty that 

 eggs of predaceous fish, especially the floating eggs of the 

 Ophioce/>halid(e family, will be accidentally carried.
