Abstract
THE latest issue (vol. x. No. 4, May, 1918) of the Journal of the Marine Biological Association contains several papers of interest to fisheries investigators. Mr. D. Ward Cutler writes on the question of age-determination in fishes by inspection of the growth increments in the scales. The latter are built up of “sclerites,” which are arranged in concentric, or rather confocal, bands, the focus being somewhere near the middle of the scale. Some of the bands of sclerites (those formed, during the summer months) are relatively wide; the others that are formed during the winter months are relatively narrow. Thus the scale shows “annual rings of growth.”
