204 TWELFTH ANNUAL REPORT OP THE 



vSo far no method has been found of getting rid of the adults, but the 

 early stages can be disposed of easily by the introduction of top minnows, 

 small sunfish, or other small fish that feed at or near the surface of the 

 water where the parasitic larvae are swimming. These fish eat the larvae 

 just as they do other small Crustacea and so get back at them. 



You will find a good description of the adults in Baird's " British Ento- 

 mostraca," while the only thing published on the development is an article 

 by Edouard van Beneden, entitled " Developpement des genres Anchorella, 

 Lernaeopoda, Brachiella et Hessia," published in the Bulletin de l'Academie 

 Royale de Belgique, (2), Vol. XXIX, p. 223. This latter article does not 

 deal with the particular species in question, but with other closely allied 

 species. 



Rainbow Trout. 



This introduced species appears to be growing in favor in manv portions 

 of New York. A very great difficulty in stocking streams with rainbow

trout arose from its migrator}' habits. But in localities furnishing suitable 

 conditions as to the size of the lake and other essentials it appears to give 

 good satisfaction. Some years ago the South Side Sportsmen's Club of 

 Long Island thought the rainbow unworthy of its attention and desired 

 to get rid of its entire stock, but now the members have splendid fishing 

 in the brackish water of Great river, and the trout run up into the stream 

 to spawn in fresh water, usually beginning in January. Other Long Island 

 clubs are restocking their waters with rainbow trout. One excellent reason 

 for this return to the rainbow is its immunity from the ulcer disease which 

 affects brown trout so seriously on Long Island and elsewhere. 



It is practically useless to collect eggs from old stock fish. This has 

 proved to be the case at three of the trout stations. The old fish yield
