Differences between the omnivorous and carnivorous fishes
7 s to amounts of radioactivity in comparable tissues were greatst on March 26, 1954.
These differences decreased with pass-
; ge of time and by January 29, 1955, were negligible in some
geissues (Figure 4, Table III).
These same data when analyzed
By definite species of omnivorous fish (damselfish) and car-
: hivorous fish (grouper) show the same trends (Table III).
Variation in radioactivity, associated with area and reated to fallout and current movements within and sround the
ftoll, indicates an increase in the contamination of the atoll
om south to north (Figure 5, Table IV).
The lagoon fish
ken in the northern part of the lagoon, off Kabelle or Mellu
peland, are comparable in levels of radioactivity to reef fishes
paken in this region.
The two flying fish taken outside the atoll
Bre remarkably alike in tissue radioactivity.
