Not illustrated. 1896 Excerpt: ...nearly everywhere, the keeled scales of the belly being well formed. The dorsal fin was now in front of the pelvic, and in some specimens the dark spot on the shoulder was visible. It would appear from this that the transformation of the twait shad is a little more rapid than that of the spring herring in the Schlei; and that the fish at the completion of the process are on the average somewhat shorter than the herring, although the difference is not great. Young shad from the stow-nets were examined and measured by Ehrenbaum at brief intervals from July onwards, and the following records show the rate of growth: --July 30, 1893 I'8--2'8 inches. August 10, 1892 I'68--2-52, August 15, 1891 2-08--312., August 17, 1893 2-16--3-24 September 20, 1S93 2-88--4-88, October 6, 1S91 2-76--3 44, October 15, 1891 3-08--3-88, November 15, 1891 3-2--4-96, Records of the number and length of young shads captured in the stow-nets at the mouth of the Meuse in Holland have been published in Dutch fishery journals. To summarise these records, with regard to the twait shad, in the month of October eightytwo specimens were taken, the smallest 2-16 inches long, the largest 6 inches, but the majority 3 to 4 inches. These may be considered the produce of the previous spawning season. In April ninety-three specimens measured 3-56 to 3-68 inches. This shows that some specimens nearly a year old are scarcely bigger than others at five or six months. In June thirty-one specimens were 3 inches to 5 inches. But these results appear to show only the under-sized specimens at one year of age; there must be others from 5 to 7 inches. Of the allis shad the October specimens, 104 in number, were 2 32 to 572 inches, the majority at any rate being fish of the year; the June specimen...
