EARLY RECOVERIES OF FIN-CLIPPED QUINNAT SALMON IN NEW ZEALAND (NOTE)

M. Flain

Fisheries Laboratory, Marine Department, Christchurch, New Zealand

Abstract Early Marine Department records (1930-42) show that of about 100,000 parr, of quinnat salmon Oncorhynchus tshawytscha (Walbaum), fin clipped at the Marine Department's Hakataramea Salmon Hatchery in south Canterbury, only 3 were positively recovered; later independent readings of scales from these fish agreed with the known age. A further 11 scale samples (for 1937 and 1939) of fin clipped fish have been read, but details of their recovery and of their fin-clip combinations cannot be found. Thus, from approximately 100,000 fin clipped parr, only 14 recoveries can be substantiated.
