type of netting, mesh sizes ranging from 1/4 inch 

 upward can be obtained. The third type of netting 

 material used by fish-culturi sts and bait dealers is 

 called "birds eye" or bobbinet cloth. This material 

 is a fine-woven fabric and is excellent for use in 

 collecting small fish (fry). 



The net should be picked according to the Job. A 

 1-acre circular pond can be seined very effectively 

 with two hauls of a 200-foot net, 6 to 12 feet deep. 

 A pond that can be drained to a seining pool can be 

 seined much more easily with a 30-foot net. A net 

 that is too long for the job is cumbersome to use and 

 increases the chance of injury to the fish. For seining 

 in public waters the net should be at least of 1/4-inch 

 mesh so that the minnows too small for use can escape 

 for further growth. In a small production pond a 

 bobbinet seine can be used to transfer the small fish 

 to a wintering pond. (fig. 13). 



When possible the seine should be landed on a 

 firm sandy bottom. The silt stirred up on a soft 

 bottom adds to the discomfort of the fish and may 

 cause suffocation. When there is danger o f suffocation, 

 smaller hauls should be made and the fish should be 

 bagged and moved to deeper water as fast as possible.
