A larval river-nuissel (Qiiadrula hcros) on the Eel has heen reported by 

 Howard ('14, p. 34); and Arcidens confragosus by Wilson ('16, p. 338L The 

 Eel is infested also with a parasitic eopepod or fish louse, . Irgulits laticaiida Smith 

 (Wilson, '02, pp. 648, 705). 



In Europe a bacterial disease, the red plague, is caused in the trout by Bacillus 

 anguillarium Canestrini. (See Bean, '07, pp. 139-142; Hofcr, 'cXj, pp. 15-19.) 

 In captivity the Eels are said by Bean ('02, p. 293) to be "particularly liable to 

 attacks of fungus, which do not always yield to treatment with salt or brackish 

 water but the parasite can be overcome by placing the Eel in a poorly lighted tank." 



Economic Relations. We are indebted to Mr. C. F. Davison and Mr. H. N. 

 Coville of Brewerton, for the following items concerning their Eel fishing opera- 

 tions. Eels are taken in various parts of the lake, but the main catch is made at 

 Caughdenoy, four miles down the Oneida River, just below the large dam which 

 controls the level of Oneida Lake. Here are two rows of weirs, each consisting of 

 three traps or pots (Figs. 224, 225). The Eels are trapped when at maturity they 

 descend the river to spawn in the sea. They are then taken from the traps and 

 stored in cages (Fig. 227) until a sufficient number has l)een accumulated to sell. 

 These were formerly sold at Brewerton to Davison and Coville, who smoked and 

 marketed them. About 100 tons of Eels were handled a year. Of these about 

 three tons were smoked. .Miout 300 jiomids were smukecj each week. Inmi tin'
