The tags were received from the factory in numbered bays of 500. They were then sterilized, coated with an antibiotic paste (tetracycline in alba), and packed in aluminum foil in packs of 50. Each pack was numbered with the series number, and all 500 banded together ( Figure 2).. 2 — Fifty tags are packed in a single layer in aluminum foil with tetracycline anti- biotic paste. Ten packages are bound together in a 500-tag lot. Photograph by Jack W. Schoit. TAGGING PROCEDURES Two tanks were used aboard the tagging vessel, one to hold untagged fish and one to receive tagged fish. The anchovies were dipped from the holding tank and placed in a shallow plastic tray supplied with flowing seawater. They were then caught by hand, tagged, and released into tin1 receiving tank. On several tagging trips, only one tank was avail- able and it had to be used concurrently as the holding and the receiving tank. Fish mortalities were generally higher under this latter condition. Tagging methods, based on tagging and mortality experiments con- ducted by Vrooman, Paloma, and Jordan (1966), were as follows. A pack of 50 tags was opened and placed in a slot cut into a block of wood.
