Channel Catfish 



One hiindred and ninety-one channel catfish weighing kSS pounds were 

 caught. The mean catch for the entire season was 0.6 fish per net lift 

 and 1,1; pounds of fish per net lift. Mean catches for individual netting 

 periods fluctuated from no fish at all to 1.9 fish and U.6 pounds of fish 

 per net lift. Channel catfish were most effectively taken in trap nets 

 during their spawning period in June and July, Very few were caught 

 after the last of July. Catch fluctuations were similar in the large 

 mesh buffalo nets ^et in the main channel. A drop in catch during the 

 latter part of June coincided with a period of cool Heather, almost 

 daily rainfall, and a few degrees drop in water temperature. It is in- 

 teresting that this sudden but temporary decline in channel catfish was 

 predicted by the commercial fishermen who handled the nets with the 

 author, 



Flathead Catfish 



Eighty-three flathead catfish weighing 390 pounds were caught. The 

 mean catch for the entire netting season was 0.3 fish per net lift and 

 1.3 pounds of fish per net set. Mean catch for individual netting periods 

 fluctuated from 0,02 to 0.7 fish and from 0.05 to 3.h pounds of fish per 

 net lift. Like the channel catfish, most of the flathead catfish were 

 caught in trap nets during their June- July spawning season, A drop in 

 catch rate, less than that of the channel catfish, occurred with the cool 

 rainy weather during the latter part of June. Flathead catfish were 

 taken fairly reKularly during most of the season in large mesh buffalo 

 nets set in the main channel. 



Carp 



Six hundred and forty-four carp weighing 2,317 pounds were caught 

 in trap nets during the season. The mean catch for the entire netting 

 season was 2.0 fish per net lift and 7.3 pounds of fish per net lift. 

 Mean catches for individual netting; periods fluctuated from 1.3 to 2.6 

 fish and from 3.i| to 11.3 pounds of fish per net lift. There was less 

 fluctuation in the carp catch when expressed as numbers of fish than in 

 the catch of any other species. There did not seem to be any particular 

 trend in catch fluctuation although catch was lowest during August and 

 the first peirt of September. 



Northern Redhorse

 caught in trap nets during the season. The mean catch for the entire 

 season was 0.6 fish per net lift and l,k pounds of fish per net lift.
