The marine light was used at night with the intention of 
measuring the abundance of fish attracted to it by keeping a record of 
the number of hours that the dip nets were used in pioking up fishes* 
In all IS stations were worked before July 1, totaling 42 l/2 hours* 
resulting in the capture of 5*123 fishes, besides several quarts of 
crustaceans and o invertebrates* After July 1, 15 stations were 
worked* totaling 30 l/2 hours, resulting in the oapture of 8056 fishes 
from Rongelap and Bikini Atolls* It was concluded that the grefct 
variability of the results with the light at night made definite 
oonstlusians in regard to abundance of fishes open to very serious error* 
Summarized in the aooompanying table are 6 stations run by 
Brook and Herald. in the deep water of the lagoon over coral heads* 
resulting in the capture of 2*171 fishes that were preserved. 
In addition before Able Day 564 other fishes collected by 
e 
various means were preserved* with 23 more discarded because of their 
large size* After Able Bay numerous miscellaneous collections were made 
resulting in the capture of 480 fishes* 
All of the fishes mentioned above are being sent to the 0* S* 
Bational Museum where they will be studied by Dr* Leonard P. Sohultz and 
probably by Dr. Bari S. Herald. This makes a grand total of 43,969 
fishes picked up during the progress of the reef fish studies* 5*260 of 
which were discarded as duplicates leaving a total of 38*709 preserved 
fishes 4n which a final repport will be made during the next few yeaes*
