250 PISHES OF NOKTH CASOLINA. 



trout ", it is caught in seines hauled for shad; and in the upper river near Weldon 

 it is rare and known as "salmon". 



It has been thought by some persons that this species was not native to 

 the Albemarle region, but Mr. S. G. Worth considers it iadigenous to those 

 waters, and the National Museum contains a specimen collected by J. W. Milner 

 at Avoca as long ago as 1878. Salmon Creek is the suggestive name of a small 

 stream between Chowan and Roanoke rivers. 



The pike- perch spawns in early spring, in shoal waters. The eggs are .08 

 inch in diameter , and resemble those of the shad in being semibuoyant but differ 

 therefrom in being adhesive. The number laid is about 45,000 for each poimd 

 of the female, and the hatching season is a little less than 3 weeks in a watei tem- 

 perature of 45°F. In hatching the eggs artificially the tendency to adhere in 

 masses is overcome by separating them mechanically with starch or muck, which 

 is mixed with the eggs immediately after fertilization. 



The species ranks high as a game fish, and is easily lured with artificial fly, 

 trolling spoon, or baited hook. The natural food consists mostly of soft-finned 

 fishes, with a variable proportion of insects and crustaceans. 



Its edible qualities are excellent, the flesh being firm, white, and well-flavored; 

 and it stands shipment better than most fishes. In North Carolina the com- 

 mercial value of the species is small.
