Abstract
MAY I ask the co-operation of readers of NATURE—fish culturists and anglers—in testing the reliability of some experiments which were designed to ascertain the numbers of trout fry which survived out of a given number distributed in depleted trout streams? The importance of the experiments can scarcely be overestimated, because if corroboration of the Board's results is obtained in different parts of Canada and in the United States, then, if economic results are aimed at, fry will have to be rigidly excluded from all waters excepting those which are known to be suitable.
