Electro Fishing, Using a Boat as the Negative

The use of an aluminum boat as the electrode on streams and rivers is quite simple and is as effective as the electrodes suspended from the side of a boat. This eliminates the need of any electrodes hanging over the side of the boat and allows the operator to work efficiently through trash and submerged obstaeles. It is necessary, if using direct current or pulsed direct current, to connect the negative lead to the aluminum hull of the boat instead of to the electrodes suspended on each side. The individual items required and their use in this operation, e.g., variable voltage...


A Dynamite Sampling Study on the Hiwassee and Ocoee Rivers in East Tennessee

In the winter of 1960 and 1961 the Tennessee Game and Fish Commission received reports that fish kills had occurred on the Hiwassee River. During the month of March, 1961 a study was developed on the Hiwassee and Ocoee Rivers to determine the fish population and to locate as accurately as possible the area or areas of adverse conditions relative to fish survival. Six stations were selected in cooperation with the Tennessee Stream Pollution Control Board. Due to the large volume of water the percussion method was employed as a sampling technique. At two of the six stations carp were...


Development of Tennessee Fish Protection Surveillance System

Increased population and industrial pressures have focused attention on the need for an accelerated and effective program to prevent and control pollution-caused fish kills in Tennessee waters. A training program to facilitate more rapid and accurate determination of the extent, severity, and probable cause or causes has been developed by the Tennessee Game and Fish Commission. Game and Fish Officers are located in each of Tennessee's 95 counties, and they comprise a readily available source of manpower to implement the program. The Officers must be specially trained in fish welfare so...
