The young of these little hakes, which are greenish blue on the back with silvery sides, are separable from rockling by their more elongate form and by the arrangement of the pigment, which is not in a band but scattered (this requires veri- fication on larger series of specimens). Older stages are identified by the presence of two well-developed dorsal fins, and the silvery sides mark them at a glance from the dull-colored fry of the cusk (p. 466). Commercial importance.—Though sof t-meated, both the common hakes—" squir- rel" and "white"— are excellent table fish and are readily absorbed by the market. The greater parts of the catch is made on line trawls. 21 Agassiz and Whitman (1885, p. 24), provisionally identified as "rockling" certain eggs with pigmented yolk taken in the tow net at Newport, but they may have been hake. 22 The single post-anal pigment band, short stocky form, and fanlike ventrals of the younger larval stages (PI. VII, figs. 1-4) which he pictured under this name suggest identity with the four-bearded 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 United States Fish Commission.
