TOTALS 12729 338.0 



Pirate perch, American eel, Yellow bullhead and Redfin pickerel were 

 the most numerous species in Hoggard Mill Creek, making up 79.2 per- 

 cent (pooled estimate) of the total (Table 3). Total estimates ranged from 

 17,656 to 103,891 fish per surface hectare and biomass estimates ranged 

 from 218.8 kg to 1606.9 kg per surface hectare among the four sections 

 sampled. The Pirate perch was the only species abundant in all sections. 

 As in Duke Swamp there was considerable variation in the number of in- 

 dividuals of several species between study sections. Section 2, the section 

 with the greatest fish density, primarily contained juvenile American eels, 

 while Section 21 had a density of only 74 eels per surface hectare. 



In Duke Swamp 70 percent of the estimated total fish biomass was 

 made up of Redfin pickerel, Yellow bullhead and Brown bullhead. Most 

 of the additional 30 percent was composed of American eel, Flier, Pirate 

 Perch and Creek chubsucker. Six species — Yellow bullhead, Redfin 

 pickerel, American eel, Pirate perch, Flier and Mud sunfish — composed
