| Summary: | Progress Code: completed Maintenance and Update Frequency: notPlanned Statement: Sharks were tagged either with Petersen discs (grey or white) attached through the first dorsal fin with stainless steel wire, or with white plastic internal tags (35 mm long by 10 wide or 50 mm long by 23 wide). The internal tags were implanted in the body cavity through an incision in the body wall. Relatively few sharks were single-tagged with either the fin or internal tags; most were double-tagged with various combinations of fin and internal tags. Credit Mick Olsen Credit Grant West. Between 1947 and 1956 a study lead by Mick Olsen resulted in 6502 school and 587 gummy sharks being tagged in south-east Australia. Most of the school shark were tagged in inshore bays and estuaries, notably Port Phillip Bay, Port Sorell, Georges Bay and Pittwater. Most of the gummy shark were tagged in inshore areas around Flinders Island and the north coast of Tasmania. A total of 594 school shark and 60 gummy shark were recaptured. This data set includes field sheets and the tags returned to CSIRO. These records are cataloged in the TRIM Records database, as follows: AB2008/1038: CMAR - School and Gummy Shark Tagging by CSIRO in Southern Australia 1947-1956 - Mick Olsen and Grant West - MarLIN record 8218 This Archive Box number incorporates 2 containers: "C2008/6921-01: CMAR - School and Gummy Shark Tagging by CSIRO in Southern Australia 1947-1956 - Mick Olsen and Grant West - MarLIN record 8218 - Part 1 - Tag Data Field Sheets" [associated files lodged within as separate objects]; and "C2008/6921-02: CMAR - School and Gummy Shark Tagging by CSIRO in Southern Australia 1947-1956 - Mick Olsen and Grant West - MarLIN record 8218 - Part 2 - Tags and Olsen Card Index [in metal filing cabinet]"
