Shrimp on dryine: platform protected against 

 rain by tarpaulins. 



Discussion. 



Dr. Embody: Are there any questions on the subject dealt with 

 in this very interesting paper? 



Mr. Titcomb: May I ask what the density of the salt water was in 

 which you found the shrimp? 



Mr. Tulian: They come up into Lake Ponchartrain and Lake Sal- 

 vador where the density is about one per cent. 



Mr. Fearnow: I wonder if I could get some information in regard 

 to the shrimp that are found in great abundance near the spillway at 

 the Gatun dam in the Panama canal. The shrimp are found there two 

 or three inches thick all over the concrete work. Apparently they are 

 trying to get into fresh water. Ls it the habit of the shrimp to go into 

 fresh water at certain periods? 



Mr. Tulian: There are three or four different varieties of salt 

 water shrim.p. Probably the one you refer to is closely related to what 

 we call the river shrimp — fresh water shrimp. It is considered a del- 

 icacy in New Orleans. 



Mr. Fearnow: These shrimp came out of the salt water and got 

 on to what is known as the apron, right below the spillway. 



Mr. Tulian: If they had got into the fresh water it would have 



done for them. 



Mr. FEARNO\y; 



Mr. Tulian: 

 up to the apron. 



Mr. Fearnow: 

 is 300 feet long and the water is very swift on it. It is fresh water. 



They were up on the walls to a great height. 

 Probably there was a certain amount of salt water 



No, there was salt water to the apron, but the apron
