摘要:

This paper outlines a program of coordinated “fish management”; compares our present work with such a program; and points out the need of a change in our basic policies to permit maximum efficiency in our efforts. The paper stresses the point that fish cultural activities, stream improvement work, research, etc., are carried on independently and with somewhat different objectives in view, and that we need a central planning and administering agency to keep all efforts directed toward the common goal – “good” sport fishing.

摘要:

For successful management objectives must be kept clearly in mind. The primary purpose of management is to provide satisfactory fishing for the largest possible number of anglers at a reasonable cost. Another objective is to provide sport rather than food. It is also important to provide good fishing throughout the season. It is believed that in heavily fished streams medium-sized rather than large trout should be the aim of management. The open season should coincide with the time fish are in best condition and weather is most enjoyable. At present the season usually opens too early. To obtain the best results management should rely on methods that have been shown to be effective. Stocking as practiced in the past has often been a complete failure. Success cannot be expected unless healthy fish are planted by proper methods in waters to which they are best suited.

摘要:

Ideal natural stream conditions exist over the greater part of Great Smoky Mountains National Park, and carefully planned management measures are in operation. Fishes taken for sport and food are the eastern brook trout, rainbow trout, smallmouth black bass and rock bass. Rainbow trout are used to fill the gap between the waters capable of supporting eastern brook trout and those in which smallmouth bass are native. Native species are stocked in virgin waters, in research areas, and in streams where rainbow trout are not well established.

摘要:

Brook (Salvelinus f. fontinalis), rainbow (Salmo gairdnerii irideus), and brown trout (Salmo trutta) fingerlings were fed diets in which fresh meats were supplemented with dry animal and plant meals. Ten diets were employed including one of pure sheep liver for comparison.
