The Effects of Seasonal Changes and Turbidity on Swimming Performance in White Crappie Pomoxis Annularis and Black Crappie Pomoxis Nigromaculatus.
… on swimming performance in black crappie Pomoxis nigromaculatus and white crappie Pomoxis annularis. These closely related fish co-occur and their relative abundance is thought to be governed by the levels of turbidity in the form of suspended sediments. Black crappie predominate in clear …

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 % insects, 14.5 % …

Impacts of the Invasive White Perch on the Fish Assemblage of Kerr Reservoir, Virginia
… bass (Micropterus salmoides), crappie (Pomoxis spp.), and self-sustaining striped bass (Morone saxatilis). Trophic relationships between white perch and resident sportfish were examined in the Kerr Reservoir system to determine the white perch's impact on them. Striped bass eggs were …

Exploring the ecological differences between black crappie and white crappie
Black crappie (Pomoxis nigromaculatus) and white crappie (Pomoxis annularis) are two closely related species that support a vital catch-and-keep fishery in the central and southern United States. Management of these two species is often plagued by poor growth and unpredictable swings in …

Evaluation of a 23-cm (9-in) Minimum Length Limit for Black and White Crappies in Lake Alvin, South Dakota
… a 23-cm (9-in) minimum length limit for black 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 …

Foraging of juvenile crappies in turbidity: the difference is black and white
… behaviors, and thus growth and survival. Black (Pomoxis 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 …

Evaluation of Walleye X Sauger Hybrid Introductions in South Dakota Waters
… 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 many …

An Evaluation of Relative Weight as an Indicator of Body Composition and Nutritional Status in Wild Fish
… 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 specialization …

Factors Affecting Recruitment of Black Crappies in South Dakota Waters
… during spring 1995 to identify black crappie Pomoxis nigromaculatus nest sites in one South Dakota impoundment (Richmond Lake) and one natural lake (Brant Lake). Individually coded ultrasonic transmitters were implanted into the body cavity of 15 adult male black crappies in each water body …

Structure, Dynamics, and Movement Patterns for Crappies in South Dakota Waters
… 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 fish. …

Food Habits of Young-of-the-Year Fishes in Abbey Pond, South Dakota
… bluegill (Lepomis macrochirus), black crappie (Pomoxis nigromaculatus), yellow bullhead (Ictalurus natalis), and yellow perch (Perca flavescens) were studied during 1973 and 1974 in Abbey Pond, South Dakota. Organisms found in young-of-the-year fish stomachs and in plankton samples were …

Fish invasions in the Mid-Atlantic region of the United States
… to the north, characterized by black crappie (Pomoxis nigromaculatus) and a second to the south characterized by white crappie (Pomoxis annularis). Nonnative community type was correctly predicted 80% of the time by models based on temperature and range in elevation. Relatively uninvaded …

Influence of Saugeye on Black Crappie Populations in Two Northeastern South Dakota Impoundments
… and Mina, 2) determine changes in black crappie Pomoxis nigromaculatus populations that were potentially associated with the saugeye introductions in Lakes Richmond and Mina, and 3) determine food habits of saugeye in Lake Richmond. Saugeyes were stocked at a total length of 3 to 4 cm in 1992 and …

Juvenile crappie growth and bioenergetics: implications for management using blacknose crappie
Collectively, black crappie Pomoxis nigromaculatus and white crappie P. annularis make up important harvest-oriented sport fisheries across North America, especially in the Midwest. Over the past several decades, the major management issues facing crappie populations have been identified as poor …

Seasonal Investigation of Native Fishes and Their Habitats in Missouri River and Yellowstone River Backwaters
… <em>Ameiurus melas</em> and white crappie<em> Pomoxis annularis</em> were residential and abundant in the backwater communities. Age- 0 bigmouth<em> Ictiobus cyprinellus</em> and smallmouth buffalo l. bubalus were also abundant in autumn after being spawned in the backwaters during the flood …

Survey of the Fishes and Habitat of Western South Dakota Streams
… bass (Micropterus salmoides), black crappie (Pomoxis nigromaculatus),and Johnny darter, were found only in tributaries. Flathead chubs were widespread and were abundant in the White River basin, where maximum age was VI. Mean back-calculated total lengths at age were 55-, 76-, 93-, 110-, 132-, …

Utility of Walleyes and Saugeyes as Secondary Predators in Small South Dakota Impoundments
… 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>
