pounds. In Lake Mattamuskeet it is very numerous, attains a large size, and is 

 the most highly prized and important fish there found. In New, Neuse, and 

 other rivers of the southern part of the state the fish also abounds. 



The spawning season in Albemarle Sound begins between April 1 and 10 and 

 continues for about ] days. At that time there may be observed in the sound 

 and its tributaries large numbers of white perch 2 to 3 inches long and doubtless a 

 year old, which mix freely with the schools of minnows, silversides, and mullets. 



The white perch feeds on minnows, shrimps, and other animals. It is one 

 of the best of American game fishes, and is a favorite with anglers; it takes the 

 artificial fly readily, and also bites at minnows, worms, etc. As a pan fish it has 

 few superiors, and is by many persons preferred to any other species. 



The annual catch of white perch in North Carolina in recent years has been 

 about a million pounds. In 1902 the fishermen sold 94 1,000 pounds and received 

 $62,666 therefor, most of this yield coming from the seine and pound-net fisheries, 

 and nearly half of it being credited to Currituck Sound. 



Genus EPINEPHELUS Bloch. Groupers. 



A numerous genus of large marine food-fishes, inhabiting tropical and sub-

 robust, compressed; mouth large, with a few large canine teeth in front of jaws, 

 and with enlarged, depressible inner teeth in each jaw; maxillary large, supple- 

 mental bone well developed and scaly; preopercle serrate; opercle with strong 

 spines; gill-rakers short and few; scales small, ctenoid, those of lateral line tri- 

 angular and cycloid; dorsal fins continuous, with 10 or 11 spines; anal spines 3, the 

 second usually largest; caudal fin concave or rounded; pectorals rounded, short; 

 ventrals close together, with a strong spine. Of the 12 or more American
