The term “fishery resources” is used in this book with a broad application. It includes the populations of the fishes and other organisms useful to men, the environment that makes life possible for them, the industry that exploits and utilizes them, and our knowledge about them by which we can conserve their productivity. This book aims to survey the present status of all these aspects of those fishery resources that are used or are available for use by United States anglers and commercial fishermen. It is planned primarily for the Congress, at its request, with the idea of giving to busy people, in condensed fashion, a perspective on its subject.

As the nature of the inland waters of a country is dependent upon its geography and geology, a brief description of the physical features of the Cape Province follows as an introduction to this report. The Cape Province covers an area of 277,200 square miles, which is approximately 60% of the total area of the Union of South Africa. It has a rugged coastline of approximately 1,600 miles, which is washed by the cold Atlantic Ocean on the west, and the warmer Indian Ocean on the east. In the north it is partly bounded by the Orange River and Basutoland. The boundary with Natal is formed by the Umtamvuna and Urnzimkulu river system. Occupying a position between latitudes 240 40' and 340 50' south, it is well within the Temperate Zone. Geologically, the Province is composed by the Karoo System; a large tract of older granites and gneiss in the north-west; the Cape System; smaller areas of the Transvaal and Nama Systems and scattered outcrops of younger granites and the Cretaceous System. Large areas are covered by windblown or shrub-covered sand. Physically, the Province can be divided into a series of plains shelving
