Abstract The distribution of 376 salmon caught at sea between 41 °S and 46 °S up to 48 km off the east coast of the South Island between 1925 and 1978 is discussed. The distribution appears to be related to strong currents in Cook and Foveaux Straits, and to the Southland Current off the east coast of the South Island. Samples from the sea at Moeraki Peninsula had a higher incidence of stream-reared fish and a lower mean fork length than samples from the Waitaki or Rakaia Rivers at spawning.

Keywords Oncorhynchus tshawytscha; growth; food; predators; distribution.
