Anadromy in North American Salmonidae, by

George A. Rounsefell, Fishery Bulletin 131 (From Fishery Bulletin of the Fish and Wildlife Service, vol. 58), 17 pp., illus., printed, 20 cents, 1958. Experimental Exploitation of Fish Populations, by Ralph P. Silliman and James S. Gutsell, with the technical assistance of Clarence E. Dunbar and Saufley B. Friddle, Fishery Bulletin 133 (From Fishery Bulletin of the Fish and Wildlife Service, vol. 58), 40 pp., illus., printed, 20 cents, 1958. The primary objectives of the work, described in this report, were to learn as much as possible about the reaction of fish populations to different rates of exploitation, to discover the relation between equilibrium yield and exploitation rate, and to establish principles of exploitation which would be applicable to commercially-utilized fish populations. An additional objective was to find how many of the known facts regarding population changes would be revealed by the conventional measures of total catch, catch per unit of effort, and mean length of fish in the catch. Four laboratory populations of guppies were grown in small aquariums under controlled light, temperature, and food supply. Two of the populations were selected by lot as controls; the other two were used as experimental populations for application of various fishing pressures. Successive application of fishing rates of 25, 10, 50, and 75 percent per triweekly period produced major changes in the experimental populations not duplicated in the controls. The general effect of exploitation was to produce a decrease in the size of the population, the amount of the decrease varying upward with the exploitation rate, until at the 75-percent rate the test populations were extinguished. Abundance and size composition of the stocks followed classical conception derived on theoretical grounds. Equilibrium yield was found to be related to fishing rate in the manner of a humped curve, with maximal yield at fishing rates between 30 and 40 percent, when the populations were at approximately one-third their asymptotic weight. The yield of fish flesh at the maximum represented about one-fifth the weight of the food consumed. The conventional fishery measures--catch, catch per unit of effort, and average fish length-were calculated and were found to yield a large amount of information about population size and results of changes in rate of exploitation.

For storage periods of 1-2 months, temperatures ranging from -6 to -10° C. are recommended.
