Preliminary results of testing of PIT-D device at deepwater longline fishery of Antarctic toothfish (D. mawsoni) in the Ross Sea during the fishing season of 2006/07

Preliminary results of testing of a PIT-D device for autonomous measurements of temperature and pressure at deepwater longline fishery of Antarctic toothfish D. Mawsoni in the Ross Sea during the fishing season of 2006/07 are presented. Diagrams of a Spanish-type longline sink rate at deployment and water temperature on various horizons are shown.
