In many reservoirs predation on stocked fish has been considered as one of the major limiting factors in establishing a particular population. Following several years of water quality determinations it was found that Lake Ouachita maintained a sufficiently oxygenated hypolimnion to support trout. As a result several thousand catchable rainbow trout, Salmo gairdneri, were stocked into the lake. The results of this attempt to establish a trout fishery have been disappointing for a combination of reasons; however, while collectint for brookstock chain pickerel, Esox niger, and from...

The history of the "nursery' area concept in fisheries management dates back several years and includes varying techniques including fencing of a shallow bay of a reservoir to protect fish on their spawning grounds, utilizing sloughs adjacent to reservoirs for spawning grounds and making use of sloughs, old river lakes and small ponds as nursery areas for young fishes which during high water migrate into the river. One of the most recent modifications which has been put into effect on five of the major reservoirs in Arkansas includes a separate structure nursery pond which is built...

Blue Mountain Dam, a flood control project on the Petit Jean River in west central Arkansas, was completed in 1947 impounding a 2,900 acre reservoir. The reservoir is relatively shallow, receives strong wind action and has a watershed to lake area ratio of over 100:1. Since four to five years after impoundment, the lake has been plagued with heavy concentrations of colloidal turbidity and a fish population dominated by non-foragable sizes of buffalo, carp, drum and gizzard shad. Combinations of fall-winter drawdowns, commercial fishing for nongame species, a selective shad kill...
