DiffiCQlfies in P15I) Caltare 



By Tarletox H. Bean, M. D., M. S. 



T is not proposed in this article to men- 

 tion all the difficulties against which 

 the fish culturist has to contend. 

 Such a paper would easily rival a 

 good-sized book in extent. What I 

 wish to do is to call attention to 

 some of the most serious obstacles 

 with which the State of New York has 

 had to deal during the past year and 

 one-half of its experience. In some 

 cases the difficulties have been over- 

 come, but in other affairs our best 

 efforts have been unsuccessful. In 

 order to facilitate reference to this 

 article, I have arranged the matter 

 under headings which are familiar to 

 all fish culturists. The article has been 

 prepared in the hope of securing, through discussion and by correspond- 

 ence, some efficient help in the struggle to maintain and increase the supply 

 of fish in public waters. 



Excess Air in Water ^uppt^ 



Eggs of maskalonge at Bemus Point, season of 1907, could not be 

 kept in the jars because of unnatural buoyancy due to excess of air in the 

 water. Eggs of shad at Catskill floated off until Mr. Walters stopped the 

 difficulty by the use of a screen through which the city water was passed 

 before entering the hatching boxes. Another method of removing the excess 

 air is by meandering the supply stream before it enters the jars and fry 



troughs.
