Barbour County Public Fishing Lake (75 acres) was stocked with approximately 500 channel catfish per acre in combination with the normal stocking rates of largemouth bass, bluegill, and redear sunfish. The lake was supplementally fed on one side only, in addition to receiving a regular fertilization program. At the end of one year of fishing, 305.5 fishermen per acre had harvested 621.8 pounds of fish per acre. Of this total, bluegill comprised 381 pounds per acre. There was no stgnificant difference between the weights of bluegill collected from the fed and non-fed areas. There...

A study was made to determine the level of dietary protein needed by channel catfish for optimum growth. The experimental work was conducted in the Farm Ponds Laboratory of Auburn University, Auburn, Alabama. Each of 40 stainless steel troughs was stocked with 25 six- to seven-inch fish. These fish were fed experimental diets at a rate of 2.5 percent of their body weight per day. Every 14 to 21 days from June 22 to September 3, 1961, the fish were re-weighed and their daily amount of food adjusted to the new weight. Eight purified diets were fed, each to five randomly-assigned troughs...
