說明

In 1907 with the object of assisting and furthering the fishing industry the New Zealand Government organized and carried out an extensive series of experimental trawling investigations, the objects, as detailed in the official reports, being 'to ascertain what extent of trawling-grounds existed, what varieties of marketable fish were obtainable in the different localities; to prove whether the conditions necessary for carrying on successful trawling existed in certain localities within workable distance of the best markets, and, if so, to place the information on record for the guidance of those interested in the trawling industry; and generally to acquire information on the distribution of food-fishes, etc., in the sea surrounding these islands.The vessel used was the 'Nora Niven', built in Selby, and was constructed of steel. She was 96 ft. long, the net register being 56 tons. In ordinary weather she could steam at 8.5 knots.The total covered during this cruise was 3,835 miles, the distance steamed being 3,123 miles, and the distance the trawl net was towed 712. One hundred and forty-six hauls of the trawl net were made. The depth of water in which the hauls of the trawl-net were made varied from 4 to 105 fathoms (7 to 191 m); and the time occupied by each haul varied from threequarters of an hour to two hours and a half. The total quantity of fish brought in and delivered to the owners of the 'Nora Niven' was 48,625lb (22,102kg).Following the success of the first leg of the expedition (see https://obis.org/dataset/5ae7ac9f-0347-49d1-b022-7739dda78ccf), the 'Nora Niven' was chartered for a further three months for the purpose of prospecting the grounds to the west of Cook Strait, Tasman and Golden Bays, down the west coast of the South Island to Hokitika, the west coast of the North Island, and part of the east coast from the Hauraki Gulf to the North Cape.Though the expedition was fitted with several scientific appliances, such as sets of thermometers, sounding-apparatus, etc., all of which were regularly and systematically used, the provision for actual trawling was of the ordinary commercial type, designed only to arrest the larger or marketable fishes.
