BROOK SHINER (Rhinichthys atronasus). 



This species of dace does not lack for local names. Its book name is blacknose dace, 

 and it is variously called rock minnow, brook minnow, rock shiner, pot belly, pottle 

 belly, etc. The last two names are derived from the frequent distended appearance of 

 the abdomen due to tapworms, with which the fish seems to be extensively affected. 



Its geographical range is extensive, and the fish is found in almost every brook and 

 in some lakes and ponds from New Brunswick and Quebec south to northern Alabama

and west to Minnesota. It feeds mainly upon insects, especially their aquatic larvae, 

 and entomostracans. It breeds in late spring and early summer. 



The only specimens collected in 1905 in this region were a few young and medium- 

 size ones in the Dead Cambridge at and above the sluice on July 22 and August 21. In 

 the Boston Society of Natural History's Museum are some specimens collected in Parma- 

 cheenee Lake many years ago.
