Food, Growth, and Reproduction of White Crappies (Pomixis Annularis) and Black Crappies (P. Nigromaculatus) in Lake Poinsett, South Dakota
… and population structures of the white crappies (Pomoxis annularis) and black crappies (P. nigromaculatus) in Lake Poinsett, South Dakota, were studied from May, 1975, to May, 1976. The total food volume of 173 adult white crappies consisted of 59.0% plankton1o crustaceans, 25.2 % …

Food Habits of Black Crappies, White Crappies, Yellow Perch and White Suckers in a Small Impoundment in Northeastern South Dakota
… food items found in stomach samples. Black crappies depended on zooplankton and aquatic insects as their major food source as they occurred in all samples and were major food items in 70 percent and 40 percent respectively. Insects, zooplankton and fish were the major food items of white …

Factors Affecting Recruitment of Black Crappies in South Dakota Waters
… into the body cavity of 15 adult male black crappies in each water body prior to spawning. Available habitat characteristics were recorded at 75 random sites within each water body, and habitat characteristics at nest sites were recorded for each male black crappie believed to be nesting. Of …

Structure, Dynamics, and Movement Patterns for Crappies in South Dakota Waters
… 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; 315-530g). From 15 April to 15 October, 1, 712 locations were recorded for 34 of these …

Foraging of juvenile crappies in turbidity: the difference is black and white
… nigromaculatus) and white (P. annularis) crappies have been hypothesized to respond strongly and distinctly to changes in turbidity, with black crappies often thought to respond more negatively than white crappies. To compare effects of three representative turbidity levels (0, 25, and 50 …

Juvenile crappie growth and bioenergetics: implications for management using blacknose crappie
… among juvenile black, white, and blacknose crappies in both experimental ponds and the laboratory. In a common garden pond experiment, I found no differences in survival among strains or ponds. Blacknose crappie outgrew black and white crappies in both length and weight and black crappie …

Evaluation of a 23-cm (9-in) Minimum Length Limit for Black and White Crappies in Lake Alvin, South Dakota
… Pomoxis nigromaculatus and white P. annularis crappies in 36-ha Lake Alvin , South Dakota beginning 1 January 1996. Both relative abundance [catch per unit effort (CPUE)] and size structure [e .g., proportional stock density (PSD)] increased following implementation of the length limit. …

Fish Populations of Two Small Impoundments in Northeastern South Dakota
… Composition of the populations differed. Black crappies were most numerous in Abbey Pond; white crappies, in Labolt Pond. Total standing crop of adult fish in Abbey Pond (573.1 kg/ha) was slightly greater than in Labolt Pond (550.6 kg/ha). Black crappies in Abbey Pond and white suckers in Labolt …

Influence of Saugeye on Black Crappie Populations in Two Northeastern South Dakota Impoundments
… face of predation by and competition with black crappies. Prior to the saugeye introduction program, Richmond Lake contained a high-density, slow-growing black crappie population. By the end of the study, black crappie growth rates had increased significantly (P≤0.05). Prior to the saugeye …

Annual Food Habits of Northern Pike in an Eastern South Dakota Natural Lake
… Thompson were common carp Cyprinus carpio, black crappies Pornoxis nigromaculatus, white crappies P. annularis, and fathead minnows Pimephales promelas. Common carp were eaten in mid-summer and again in winter. Black crappies were eaten mostly in the winter. Fathead minnows were an important …

Food Habits of Fish In A Multispecies Farm Pond
… important food item in the diet. Adult black crappies fed primarily (as indicated by number and by volume) on zooplankton and aquatic insects. Zooplankton were fed upon regardless of their availability. Daphnia galeata was positively selected while Bosmina longirostris and both cyclopoid and …

The Fish Population of Lake Poinsett, South Dakota, as Indicated By the Catch
… in the catch of yearling black bullheads, crappies, white bass, carp and bigmouth buffalo was attributed to an increase in activity or change in behavior pattern. Diurnal migrations were felt to be the cause of diel differences in catch rate of species taken by the trawl and shocker. …

Evaluation of Walleye X Sauger Hybrid Introductions in South Dakota Waters
… suggesting large scale predation by black crappies Pomoxis nigromaculatus immediately following stocking may, at least in part, explain this lack of success. However, in Lake Herman, where black crappie density was relatively low, saugeye survival was high. We captured over three times as …

An Evaluation of Relative Weight as an Indicator of Body Composition and Nutritional Status in Wild Fish
… largemouth bass Micropterus salmoides, and black crappies Pomoxis nigromaculatus. Regression models were compared to concurrent bluegill models. Piscivore models fit well (adjusted R2 > 0.50), whereas bluegill models had the lowest explanatory power (adjusted R2 = 0.13 and 0.14). Ecological …

Food Habits of Walleyes in Lake Oahe, South Dakota
… of freshwater drum, yellow perch, and white crappies. Macroinvertebrates were not a substantial portion of the diet of walleyes in August. Walleyes preyed predominately on YOY fishes except at Peoria Flats and Cow Creek where adult rainbow smelt were consumed. Most prey fishes were consumed …

Utility of Walleyes and Saugeyes as Secondary Predators in Small South Dakota Impoundments
… incremental growth rates of bluegills and black crappies Pomoxis nigromaculatus also exhibited significant increases between 1997 and 2000. These trends indicate that the stocked percids, through increased predation, were able to improve the size structure and growth of panfish in Hanson Lake.</p>
