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 …

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 …

The Effects of Seasonal Changes and Turbidity on Swimming Performance in White Crappie Pomoxis Annularis and Black Crappie Pomoxis Nigromaculatus.
… and turbidity 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 …

Influence of Saugeye on Black Crappie Populations in Two Northeastern South Dakota Impoundments
… Richmond 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 …

Impacts of the Invasive White Perch on the Fish Assemblage of Kerr Reservoir, Virginia
… for largemouth 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 …

Factors Affecting Recruitment of Black Crappies in South Dakota Waters
… undertaken 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 …

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 …

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 …

Assessing the Sustainability of Fish Communities in Glacial Lakes: Habitat Inventories and Relationships Between Lake Attributes and Fish Communities
… ruggedness was negatively correlated with black crappie Pomoxis nigromaculatus PSD, northern pike Wr, and walleye Stizostedion vitreum Wr. Lake surface area was positively correlated with walleye Wr, walleye length at age 3, and yellow perch Wr. Nitrate levels were positively correlated with …

The Fish Population of Lake Poinsett, South Dakota, as Indicated By the Catch
… and trap net catches of black bullhead, black crappie, and white crappie. A late summer increase 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 …

Reproductive Biology of the Flat Floater Mussel, Anodonta Suborbiculata, Say, 1831 (Mollusca: Unionidae)
… were observed on the fins of gizzard shad, white crappie, largemouth bass, bluegill, golden shiners, and freshwater drum, but not on common carp, nor black bullhead. Host suitability was confirmed by observing the transformation of glochidia experimentally placed on white crappie, largemouth bass, …

Effects of landlocked alewife introduction on white bass and walleye populations, Claytor Lake, Virginia
… by season of alewives, channel catfish, white crappie, walleye, and white bass are given. Each of the predator fishes seem to be found in close proximity to the alewife. Changes in the fish fauna of Claytor Lake between 1950 and 1971 are discussed. Based on the two rotenone samples taken during …

Food Habits of Fish In A Multispecies Farm Pond
Food habits of yellow perch, bluegill, and black crappie were studied during 1970 and 1971 in Abbey Pond, South Dakota. Aquatic insects, zooplankton, mollusks, and fish were the most frequently consumed food items by the three species. Yellow perch led primarily on aquatic insects, zooplankton, and …

A Comparison Between South Dakota and North American Standard Sampling Gears in Lakes and Reservoirs
… types though Standard nets captured more Black Crappies and SDGFP nets captured more Black Bullheads. Standard modified fyke nets tended to select for larger Black Crappie and Bluegills. In both MR and non-MR systems, conversion factors for lakewide catch per unit effort were developed for each …

Survey of the Fishes and Habitat in the Upper Moreau River, Perkins County, South Dakota
… common carp, emerald shiner, white bass, black crappie, and largemouth bass. Of these, white bass, black crappie, and largemouth bass comprised 0.06% of the total catch in 1995 and were considered incidental species. Yellow perch was historically collected, but was not found during this study. …

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. …

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 …

The Contribution of Missouri River Reservoir Side-Channel and Floodplain Habitats to Mainstem Fish Populations: The Effects of Losing Connectivity Between Hipple Lake and Lake Sharpe
… recruitment of Bluegill (Lepomis macrochirus), Crappies (Pomoxis spp.), Largemouth Bass (Micropterus dolomieu), and Gizzard Shad. A cold-water side-channel embayment, La Framboise, was important for White Bass, Sauger (Sander canadensis), and Walleye (Sander vitreus) natal recruitment and adult …

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 …
