sonnel detailed to the worko It is believed that the factors of 

 temperatiire, salinity and silting can be satisfactorily determined 

 for the barriers themselves in the Narragansett Bay model in the 

 Waterways Experiment Station at Vicksburg, Mississippi g and it is 

 recommended that the Corps of Engineers complete these studies by 

 June JOf 1957 o It will be necessary to conduct j, at various Fish 

 and Wildlife Service installations, studies in which the species of 

 fish involved would be subjected to various controlled environmental 

 conditions o 



ko That the macroinvertebrate life of the bottom of the Bay be af- 

 forded detailed study to determine its relative abundance and composi- 

 tiono This bottom fauna study would also represent an inventory and 

 would serve to round out the preproject picture of the Bay* a resources 

 prior to construction of barriers© Foirtherraorej it ia posisible that 

 certain of these bottom-dwelling forms may reveal themselves ^s in- 

 dicator organisms which could be employed to foretell or confirm 

 damages or benefits which may accrue from the construction of the 

 project barriers c . 



5o That additional studies be undertaken to determine the importance 

 of the Bay to populations of winter flounder c It is known that the Bay 

 comprises a spawning and nursery area for this species - This knowledge 

 is not well defined, however, and much more data are required to de- 

 termine the precise relationship of the winter flounder to the Bay, and 

 how this relationship could be affected by the construction of hurri- 

 cane damage control barriers o
