The Blue Cat 



To see white catfish as large as man, 

 Through what the bards call ' water wan, 

 Come with an ugly rush! 



" They say the CatHsh climbs the trees. 

 And robs the roosts, and down the breeze 



Prolongs his catterwaul. 

 Oh, leave him in his western flood 

 Where the Mississippi churns the mud; 



Don't brins; him here at all! " 



The spawning season of the blue cat in Louisiana is during 

 the months of April and May. Out of 374 fish examined a1 

 Morgan City, Louisiana, April 22-24, more than 04 per cent, were 

 spent fish or fish ready to spawn. 



in Louisiana this, the most valuable of all our catfishes, is 

 known as the blue cat or poisson bleu. Elsewhere in the 

 Mississippi Valley it is the Mississippi cat, the great forktailed 

 cat 01 chucklehead cat. Whether the names Florida cat, flannel- 

 mouth cat, etc., apply to this species is not certain, as the blue 

 cat and the large northern catfish (Aineianis lacustris) have not 

 been clearly differentiated.
