Lsotopes were available in greater amounts at Bogallua - carried westward from the target area by currents and wind in the
lagoon.

This is partially substantiated by the presence of

turbid water west and southwest of the target area.

It must

be noted also that much of the activity at Engebi was pre-shot
and probably made up of considerable inert material, biologically speaking.
A large number of dead and dying fish were seen in and close
to the turbid water flowing from the target area westward inside
the lagoon between Elugelab and Bogallua eight days after the
blast.

There were some injured fish at Engebi also and two or

three badly injured goatfish were collected near the shore

(Fig. 9).
Analysis by Species and by Feeding Habits.

Among those

fish which are fairly well represented in the samples, damsel
fish appear to ingest the greatest amount of active material,
followed by surgeon fish, butterfly fish, parrot fish, gobies,
wrasse,
species,

squirrel fish, cardinal fish and groupers.

Other

of which we have only a few samples, and which indicate

their ability to absorb active materials, are filefish, blennies,

puffers and eels (Table 11).

As the range of d/m/g indicates,

there is great variation from species to species, island to
isia€nd, and even from specimen to specimen, especially evident
in the post shot fish.
Omnivorous species almost invariably showed more activity
than carnivorous species from the same area.
