The food of trout in New South Wales, 1933–1934
Abstract
This paper contains the results of the investigation into the food of trout in New South Wales carried out during the season 1933-1934, and gives details of the stomach contents of 118 Rainbow Trout (Salmo irideus Gibbons), 27 Brown Trout (Salmo fario Linmeus), and 2 Loch Leven Trout (Salmo levenensis Walker). A preliminary report published in 1934 covered the results of the work carried out ill 1931–1933. This investigation aroused so much interest among anglers and those concerned in the propagation of trout in our streams that the work was carried on throughout the past season, members of the Rod Fishers' Society of New South Wales kindly submitting collections of trout stomachs from time to time. A notable feature of the stomachs examined was the large number of caddis cases found, which numbered 6,648 from 146 fish as against 188 in 1931–1933 from 44 fish. These figures conform very closely to those which have been obtained in New Zealand. ... [etc.]
