[ This station is almost identical with No. 
- S-46-215 which was run on _. The only 
jj difference is that on this occasion the poison was 
^ ' 3 put into the water nearer the Eniaetok Id shore 
whereas previously it had been put in over the area 
S 4, nearer to Erapuotsu Island. On the way to this sta- 
^ on - a H locaities between the north tip of 
4 Rongelap and these island.s were checle d carefully as 
4 : X it was planned t o run a station somewhere in that 
‘s ' area---but none suitable wereavailable-hece it a 
i, ji station was run-it was necessar??" to duplicate 
., N 0 . S-46-215. Seaman Selzer informed us that the* 
4 , previousl collection had beai extremely strong ii# 
k' eels-such was not the case for this station on 
20 Iply for only p 7 eels were collected which :V/! ' 
' £ _percent of tlfe toal catch (< if) fishes t otal) 
s suggested from this data that perhaus Yurochi 
and the outer feef of Bikini (S- 46-251 and 253 ) 
might have been poisoned, either by Donaldson’s 
bunch or by this group-and that such might explain 
the poor collection of eels at these tv/o stations. 
Is is possible that eels are much more susceutable 
to derris than areother suedes, andth-t it takes 
individuals residing in adjacentareas longer to 
migrate into a fewshly poisoned area than it does 
other suedes of fishes?
