them back. When the fish are let alone, however, they do 

 satisfactory work. 



DISTRIBUTING THE FISH 



In anti-mosquito work in which fish are used, best results are 

 obtained by making some one certain individual responsible 

 for this phase of the work. This individual should be in charge 

 of the collection, care and distribution of the fish and of the pond, 

 marsh and stream cleaning essential for their advantageous use. 



Requests for fish made by inspectors or other persons should 

 be at once turned over to the fish control foreman for action. 

 In order to speed up distribution of the fish, it is essential that he 

 have necessary facilities for his work. Among these may be 

 mentioned nets for catching the fish, suitable receptacles in which 

 to transport them and means of transportation. 



A very useful net for collecting top minnows is a small bobbinet 

 seine. A net about 12 feet long by 3 feet deep is a good size. 

 Such a net, if made of good material, is light and durable, and it 

 can be easily and quickly handled. A dip-net, also made of 

 bobbinet, may be used to advantage in places where there are so 

 many roots or so much vegetation that a seine cannot be operated. 



Almost any kind of a receptacle for the fish will do, but for 

 ordinary use in an anti-mosquito campaign, the writer suggests 

 a milk can, with a cover of gauze or burlap substituted for the 

 metal cover. When about half-full of water, such a can will 

 hold several hundred fish very comfortably and but little water 

 will splash out in ordinary travel. 



Transportation may be either by automobile, truck or wagon. 

 For ordinary use in a small town, the writer suggests a light 

 roadster with the turtle-box removed or a buggy or buckboard. 

 Such a vehicle will comfortably carry two cans of fish on the back. 

 On small jobs, it is likely that the same vehicle used for carrying 

 oil may be utilized on certain days for hauling fish. 



NECESSITY OF AIDING THE FISH 



Throughout the South, even in inland areas, it probably will be 

 found that most streams, ponds, lakes, swamps and similar 

 natural breeding-places already are stocked with Gambusia or 

 other larva-destroying fish. In such cases, very little new stock- 

 ing will be necessary, but the fish will have to be aided, if best 

 results are to be obtained.
