The Canadian field-naturalist. were observed in 1926 and a specimen of Ray's bream, Brama rail (Bloch), (Fig. 2), was taken on a Fig, 1—The Sun Fish, Mola mola Fig. 2—Ray's Bream, Brama rail SALFS Salps occur sometimes in great abundance and they cause trouble to the fisherman through becoming impaled on the hook and thus prevent- ing the spoon from working properly. They often float some distance below the surface and their presence is revealed by their fouling the spoons. One fisherman said they were in a sunk zone, one to two fathoms thick, and that the level at which they were swimming altered during the day. When he found the salps on his hooks he was able to avoid the zone by altering the length of his lines. Many of the salps floating on the sur- face were partially torn and were often covered more or less by air-bells. The probability is that some of the damaged specimens had been bitten by diving seabirds, and had, in their torn condi- tion, risen to the surface. Mcintosh has des- cribed how gulls peck at the salp on the surface and remove the "nucleus". Some of the salps observed here at the surface were minus the "nucleus". In June, 1925, large individual salps 3 inches long, probably Salpa fusiformis var. aspera, (Fig. 3), were observed off Barkley Sound. They were common off Hippa Island in July of the same year. Little salps also occur in chains, of varying thicknesses, some being less than one- quarter of an inch broad. The broadest chain observed was three-quarters of an inch Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Ottawa Field-Naturalists' Club.
