The concen- | tration of plutonium in foods, including fish,has recently taken on new significance since some data now indicat that the transfer coefficient for plutonium from digestive tract to tissue for mamma | s may be 2 to 3 orders of magnitudes greater than previously reported. ee Soa Te Since the Enewetak clean-up program is underway, the fish tagging and monitoring program should begin as soon as funds are available. Migrations and movements of lagoon and reef fishes are poorly known.

He tagged 141 fish and found six families of fishes to be transient crater residents but did not have the opportunity to determine longer migrations. Studies of sub-tropical Atlantic reef fishes indicated that their migrations range from several meters to the full breadth of coastal areas. A successful fish migration study requires an extensive program of recovery as well as tagging. Every third month about 3 weeks will be spent at Enewetak to tag as many fish as ‘possible at selected sites. Part of i the field time will also be spent-in special efforts to recover tags includina contact with the Enewetakese fishermen, sports fishermen, and researchers from the Mid Pacific Laboratory (MPL). A reward system for the return of tags captured by others will be considered. Because of the great variation in size, shape, and habits of tropical reef fishes, various types of tags - streamer, button, strap - and of gear - throw nets, traps, BOOK PAGE:
