A 305-406 mm protective slot and 4 fish daily creel limit, allowing harvest of 2 fish <305 mm, was placed on largemouth bass (Micropterus salmoides) in Lake Sutton during July 1989. The purpose of the regulation was to protect slot length bass and increase the angler catch rate for bass >400 mm. The objective of this investigation was to evaluate the regulation's effectiveness by comparing size distributions, PSD and RSD40 of fish captured by electrofishing and anglers, as well as angler catch rates of bass >400 mm, before and after the regulation change.

The anode and cathode arrangements on an electrofishing boat using pulsed D.C. output were manipulated to increase the effective area of the electric field. Voltage gradient (volts/cm) measurements were taken at various distances and depths at 90 and 180 degrees in relation to the long axis of the electrofishing boat. The objective of the study was to improve the efficiency of the electrofisher in low conductivity waters. The maximum distance and depth of field increased an average of 71% and 72%, respectively, for the 2 sample sites when comparing the initial configuration (IS-cm anode...

Five techniques (electrofishers, hoop nets, gill nets, wire traps, and trotlines) were used to sample ictalurids in the Neuse River above New Bern, North Carolina, between July 1984 and May 1985. Hoop nets were the most effective of the sampling gears tested. They collected white catfish (lctalurus catus), channel catfish (l. punctatus), blue catfish (l. furcatus), yellow bullhead (l. natalis), and margined madtom (Noturus insignis) and accounted for 76% of the total number of fish caught. Electrofishing (low voltage) captured white catfish, yellow bullhead, and margined madtom, which...
