 INTERNATIONAL AGREEMENTS OTHER THAN TREATIES [58 STAT. hensive program in the same general field, subject to the following understanding: Goapertbjtveprg.of It shall be the general objective of the cooperative program to assist in improving the food and recreational resources of the interior fresh-water fisheries of Mexico by the following means: 1. Biological surveys of lakes and streams to determine their suit- ability to support various species of fresh-water fishes from the stand- point of conditions of temperature, natural food, cover, and spawning areas; 2. The determination of stocking policies and programs for lakes and streams that are depleted or are capable of supporting greater quantities of fish life; 3. Improvements in hatchery construction and operation through the introduction of scientific methods of incubation, general sanita- tion, artificial feeding and control of diseases and parasites; 4. The training of hatchery personnel; 5. The stocking of lakes and streams with native fishes, and with imported species where desirable if eggs can be obtained (the eggs to be purchased by the Mexican Government); and 6. The development of methods of scientific management of the fresh-water fisheries to be carried out by Mexican officials. anCdW etionof Fish To attain the foregoing objectives, the Fish and Wildlife Service will cooperate with the Mexican Department of Fisheries in the following manner: (a) Make available the services of Mr. J. Adger Smyth, an Associate Aquatic Biologist of its Division of Fishery Biology, who is already known to the Mexican authorities, to direct and assist in planning the proposed program, his services to be rendered on a full-time basis; (b) Continue Mr. Smyth's assignment for a period of two years and pay his salary and other personal expenses during the two-year period, subject to the availability of appropriations.

PtrofPoseundetof- The Government of Mexico, through the Mexican Department of Me r G. Fisheries, will undertake to- (1) assign two assistants for the biological investigation and pro- vide funds for their travel and subsistence, giving preference in the selection of such assistants to persons already employed by the Mexican Department of Fisheries or to persons familiar with the fresh-water fisheries of Mexico and possessing training in biology or experience in the technical aspects of fish culture. (It is suggested that such persons be selected with a view to their future employment 1558
