The distribution of juvenile trout in Loch Leven was studied by seining, trawling and gillnetting between Oct. 1974 and Dec. 1976. Only gillnetting caught juvenile trout in significant numbers in the offshore areas of the loch. From gillnets set along 3 traverses on the loch, juvenile trout were concentrated in the offshore, above the mud zone of the loch. During the summer period, gillnet captures of juvenile trout increased with increasing depth, reaching a maximum concentration at the deepest part of each traverse. During the winter, juvenile trout appeared to be evenly distributed with no clear area of concentration. Although there were a few areas of overlap, juvenile trout concentrations seem to be separated from the adult trout, perch and pike populations in the loch.
