212 FISH CULTURE 



ing of the eggs was corrected in the following 

 manner, quoting Mr. Worth's account: 



"A better per cent, in hatching could have been 

 gained by the earlier adoption of the pitcher-mouthed 

 tops of the Universal hatching-jars, which were ex- 

 perimented with, for the first time, during the season 

 covered by this report. I had already been aware 

 that losses of fry, already hatched and delivered into 

 aquaria, were excessively large at times, and I am of 

 the fixed opinion that the cause was to be found in 

 having the fry struggle through outlet tubes of the 

 Universal jar. . . It is necessary to supply an auxiliary 

 of canvas to the lipped jar-top, in order to let the 

 fish down gradually into the aquarium. Hatched and 

 handled in this way, the results are all that could be 

 desired, for every good egg developed and all the fry 

 lived. It would be a waste of time and material to 

 undertake the hatching of striped bass in the Mc- 

 Donald tidal box, as the separation of bad and good 

 eggs would be impracticable, and there is a percent- 

 age of bad eggs ia every lot." 



The Smelt. — Like the striped bass, the smelt 

 is an anadromous fish, entering fresh water 

 from the sea early in the spring for reproduc- 

 tive purposes. It prefers rapidly running 

 streams with stony or gravelly bottoms, on 

 which the female deposits in vast quantities
