Channel catfish fry, ranging in age from one day old to about two weeks old, are routinely transported in polyethylene plastic bags with an oxygen atmosphere between fish hatcheries in Arkansas. Approximately 10,000 fry are transported per 18" X 32" bag in 1.5 gallons of well-oxygenated spring water of moderate hardness. These fish are transported by both airplanes and station wagons.

Lake Hamilton is the middle of three lakes located in series on the Ouachita River in Southwestern Arkansas. Following the initial release of water through the penstocks from the upper newest lake, a subsurface current was detected in Lake Hamilton. During the summer of 1960, physical-chemical tests were made at nine stations along the channel to determine the extent of the current. Data collected showed the water remained oxygenated from the surface to the bottom. Cold water drawn from below the thermocline of the upper lake becomes oxygenated in the tailrace and slides under the warm...

A fisheries management plan for reservoirs is proposed which is dependent upon having a fish management pool and provision for drainage incorporated into the basic design. Justification is given to support the cost of having a cleared management pool in the bottom of the reservoir as well as drainage facilities. A plan is also proposed for selective clearing of reservoir basins. The management program described is based on a philosophy of drastic manipulations of fish populations through fall and winter drawdowns, selective kills, partial kills, intensive sport and commercial fishing...

Plans for a fall and winter drawdown (1955-56) were carried out on Nimrod, a turbid, flood control lake. The surface acreage was reduced from approximately 3,600 acres to 700 acres. Commercial fishermen removed over 200,000 pounds of rough fish most of which were smallmouth buffalo. Following the drawdown and subsequent filling, the water cleared up and remained clear. An increase in the number and size of young black bass and white bass was recorded with a resultant decrease in the number of young channel catfish, carp, drum and buffalo. Larger numbers of young sunfish and minnows were...
