A Quantitative and Qualitative Bacterial Analysis of Pecan Creek
Date: 1946
Creator: Cook, Vernice
Description: Since Pecan Creek receives sewage wastes from an obviously inadequate disposal system, it seemed possible that it could receive pathogenic bacteria. The fact that these might be present in numbers sufficient to cause epidemics, provided the proper natural vectors were present, stimulated an interest in and the pursuance of this study.

Age, Growth, and Food Habits of the Largemouthed Black Bass (Micropterus Salmoides) and the Spotted Bass (Micropterus Puctulatus SSP) in North and East Texas Lakes
Date: 1950
Creator: Cooper, William A.
Description: This study is based on the examinations and analyses of 388 largemouthed black bass (Micropterus salmoides) and 118 spotted black bass (Micropterus puctulatus ssp.) which were collected over a period of three years from 9 lakes in the North-Central and East Texas areas. The results should show the following: (1) the average age of the black bass in each of the nine reservoirs in Texas; (2) the growth rate of the bass in these reservoirs; (3) the feeding habits of the bass in all reservoirs studied; (4) a comparison of the growth rates of the largemouthed and spotted basses; and (5) a comparison of the growth rates of bass from Texas and Oklahoma.
