A boat load of carp, part of a catch weighing one and a half tons 



Four such nets, each of a different sized mesh, were placed in a 

 zigzag formation beginning with the fine mesh near shore and 

 grading into the larger sizes offshore, Trap nets were used more 

 successfully for taking fish other than carp. They were used 

 singly or in groups of two or more. By joining the wing of one 

 net with the leader of another a complete barrier was produced. 

 Both trap and gill nets were set for one day a week throughout 

 the summer in Three Mile bay, where an intensive study of a carp 

 ground was made. 



The twenty-five and sixty foot minnow seines were found very 

 valuable in collecting young carp and small fish inhabiting carp 

 grounds. Either size of net could be operated by two men, and, 

 except for regions covered with dense flora, they worked perfectly. 

 A rigid trawl, made of fine mesh hardware cloth and shaped 

 somewhat like a Petersen trawl, furnished an excellent means of 

 catching small fishes living in thick vegetation. This trawl was 

 also used for deep water dredging and had an added advantage 

 of being available for a trap when not otherwise in use. 



Statistical Evidence. — From May 25 to September 21 more 

 than 45 tons of carp were seined. This represents some 8,000 fish. 

 The exact number cannot be given as accurate records were not 

 made during the first month and in the larger hauls where as 

 many as a thousand fish were successfully taken, some degree of 

 error is to be expected. Those who have not worked at carp seining 

 can hardly appreciate the difficulties. In the taking of this large 

 number of fish, three thousand one hundred and eight other fish
