Abstract
Ultrasonic telemetry was used to determine monthly and diel movements of white crappies Pomoxis annularis in a South Dakota glacial lake, Sonic transmitters were surgically implanted in 37 adult white crappies (265–327 mm, total length; 315–530 g) at intervals from 10 April through 22 September 1992. From 15 April to 15 October, 1,712 locations were recorded for 34 of these fish. Movement (m/h; measured along the straight-line distance between successive locations) was significantly different among months (P < 0.05). Movement was highest in May (102.1 m/h) and significantly different from movements in April and June, The second highest amount of movement was in July (82.4 m/h). Other than in early spring, movement did not vary significantly among months. Depth of lake at white crappie locations differed significantly among months. White crappies were in significantly shallower lake areas in June and October than in August. Distance from shore differed significantly among months. White crappies we...Keywords
