STRIPED BASS 



Striped bass fingerlings often are fed supplemental diets in earthen ponds 

 when zooplankton blooms have deteriorated or larger fish are desired. The 

 fingerlings are fed a high- protein (40-50%) salmonid type of formulated 

 feed at the rate of 5.0 pounds/acre per day. This is increased gradually to a 

 maximum of 20.0 pounds/acre per day by the time of harvest. The fish are 

 fed 2-6 times daily. 



When striped bass fingerlings reach a length of approximately 1.5 inches 

 they will accept salmonid- type feeds readily. Good success can be antici- 

 pated when a training program is followed, such as that described for 

 largemouth and smallmouth bass. Striped bass fingerlings can be grown to 

 advanced sizes in ponds, cages, or raceways. 



Attempts to rear swim-up fry to fingerling size on brine shrimp and for- 

 mulated feeds under intensive cultural conditions have been relatively 

 unsuccessful. 



Time of Initial Feeding 



There is considerable difference of opinion among fish culturists as to when 

 fry should receive their initial feeding. The most common practice is to 

 offer food when the fry swim up. Swim- up occurs when the fry have ab- 

 sorbed enough of their yolk sac to enable them to rise from the bottom of
