Subject Index Fish Research Projects 132-133 Fish Management Projects 133 PURPOSE AND DESCRIPTION OF THE SURVEY This publication reports information gathered from the principal agencies and institutions engaged in sport-fish research and management activities in the United States. As such, it is probably the first organized attempt to bring together the current programs in these fields of fish conservation. The objective of the sur- vey is to provide a catalog which will encompass work in progress to provide fishery administrators, technicians, and any others who might be interested, means for keeping abreast of modern developments in fish conservation practices. It is be- lieved that the publication will stimulate greater exchange of ideas between those en- gaged in projects of a similar nature, will aid in preventing needless duplication of effort, and will for the first time furnish a comprehensive picture of the status of our fisheries progranns. In planning the Survey, it was necessary to establish a suitable limitation on types of projects which would be covered. The principal criteria, that the Survey should include projects relating only to sport fishes and features of their habitat, was established in an effort to scale down the field covered by the report in its first year. To maintain interest in the publication, it was found desirable to exclude re- porting on routine management operations, such as law enforcement, public relations, fish stocking, et cetera. Finally, the Survey deals exclusively with work in progress. Neither past accomplishments nor future plans have been included unless these are related directly to the current work. Reports on individual projects are necessarily brief, and the space assigned does not reflect the importance of the project. In the case of some of the Federal projects, the sphere of operations may include several States. Projects are listed under the State where headquarters are established. The subject index will assist in locating the description of any project. Insofar as possible the Fish and Wildlife Service has limited its editing of completed questionnaires to the bare essentials necessary for standardization of format and attainment of clarity. Readers are urged to direct inquiries to the responsible agency as given under each project description rather than to the Fish and Wildlife Service, except where the project is listed as an undertaking of the Service. As there is no single comprehensive directory of agencies and institutions engaged in projects covered by the Survey, it is doubtless possible that some have been overlooked in this first publication. It is hoped that more complete coverage can be obtained with next year's edition of the Survey. Questionnaires will be circu- lated to correspondents in January of each year with the expectation that publication will take place near the first of March. The issuance of the first report was un- •avcidably delayed. All State Fish and Game Departments provided reports except California and Texas. Federal Aid in Fish Restoration projects currently approved were included by the Fish and Wildlife Service for California. Inasmuch as Texas had no Dingell- Johnson projects in operation prior to April 15, 1953, no report of the Game and Fish Commission projects could be made. ACKNOWLEDGMENTS Acknowledgment is made of the enthusiastic response on the part of all con- tributors. The Survey is a purely cooperative venture in -which the Fish and Wildlife Service is serving only as the clearing house and means of publication. Without the voluntary contributions of the agencies whose programs appear herein, a survey and this publication would not have been possible. The need for bringing together information on current fishery programs has been recognized by the American Fisheries Society for many years. In a resolution passed by the Society at its September 1952 nneeting, the Fish and Wildlife Service, through the Branch of Federal Aid, was requested to undertake the Survey. This has now been accomplished with the publication of the first year's reports. *s):::t **;[!** ***:(:!i<4:>}: ■.■*:}:>}:*** EXPLANATION OF PROJECT DESCRIPTIONS Material reported by the several game and fish departments, universities, federal and private agencies, is arranged in the following order: (1) Title of project (2) Objectives and description (3) General explanatory information (a) Area covered and/or location of headquarters (b) Cooperating agencies (c) Date project began and expected life (d) Estimated cost of current segment (e) Name of the project leader (f) Availability of project reports (4) Person or office to receive communications If a project is being carried out under the Federal Aid in Fish Restoration (Dingell- Johnson) program, it will carry the designation FA: and the project number after the title.

The Navajo-Hopi Indian Reservation in Arizona is typical of much of this type of country. The interest and cooperative effort of those in charge of the reserva- tion, and from many of the Indians, warrant development of angling opportunities for the Indians and for visitors. The best opportunities are in the larger reser- voirs and deep charcos (tanks) which retain sufficient water through drought periods to maintain fish populations. Development of proper species composi- tions, stocking densities, and corrective stocking measures are the principal management problems in these areas.

All of the natural lakes of Iowa managed for angling are surveyed by the Biology section each year. This involves test seining with 500 feet of l/4-inch nnesh (bar) seine at several stations on each lake. In addition, stationary gear {pound and gill nets) are used to supplement the seine catch. The small-mesh seine hauls are designed to determine primarily the magnitude of reproduction each year, and the nets to determine population fluctuations and status of the adult fishes. Fishes taken are sorted into young-of -the-year and older groups, weighed, measured, and scale samples taken from representatives for age and growth analyses. Data on vegetation, amount of bottom foods (dredge samples) turbidity and lake chennistry are also obtained. This information is recorded on forms and recommendations presented for possible improvem.ent of fishing. Northern half of Iowa; began July 1940, continuing; $5,000; Earl T. Rose, Proj.

Analysis is accomplished through the ordinary techniques applied to such surveys and includes the evalua- tion of lake quality, age and growth of fishes, and the ecological relationships of fish populations. Findings to date indicate that when poor lake fishing is found the underlying cause is usually unbalanced fish populations. Although liberalization of the regulations on pan-forage species may be desirable, perhaps greater size re- strictions on pikeperch, northern pike, pickerel, muskellunge, and bass are necessary for the purpose of increased predatory function and improved repro- duction.

The project aims to test effectiveness of several watershed improvennent measures including: (1) Control of livestock grazing, (2) reseeding, and (3) contour trench- ing for preventing the recurrence of violent mud rock floods during high intensity summer rains. The study involves several watersheds and subwatersheds totalling about 28,000 acres, some of which were intensively treated and others given only protection from grazing. A network of recording rain gauges provides a record for evaluating the depth-area-intensity relations of summer rains. Streamflow records and observations of discharges are checked against the climatic record and the treatment on specific subwatersheds. Since the improvement measures were installed, channels have become more stable and streamflow more regular.
