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. - 48 - Exceptions were
