An Evaluation of Crappie Supplemental Stocking in Arkansas Impoundments

SEAFWA Journal Volume 2, March 2015

Supplemental stocking of sport fish has been an important management tool used by fisheries management agencies, but published accounts of stocking success are infrequent. Both black crappie (Pomoxis nigromaculatus) and white crappie (P. annularis) have been stocked throughout the southeastern United States with over one million stocked annually in Arkansas alone. Stocking contribution was determined for six impoundments that ranged in size from 58 to 503 ha. In October 2010 and 2011, crappies were marked with oxytetracycline hydrochloride and stocked at rates that ranged from 53 to 246...

Potential for a Minimum-length Limit Regulation to Improve Floodplain Lake Crappie

Compared to reservoirs and small impoundments, sport fisheries management infrequently has been attempted in large-river systems. In river systems of the southeastern United States, black crappie (Pomoxis nigromaculatus) and white crappie (P. annularis) represent popular sport fisheries in floodplain lakes and other off-channel habitats. Using floodplain lakes in the lower White River, Arkansas as a study area, crappie population data from 16 representative lakes were used to define basic stock structure statistics and evaluate whether minimum-length limits could potentially improve...

Comparability of Channel Catfish Stock Descriptors Obtained from Different Hoop Net Configurations

Channel catfish (Ictalurus punctatus) stock characteristics of a small floodplain river were compared from samples collected in 1994-1996 from 3 different hoop configurations (large hoop net (LH): 4.3 long with 7 1.07-m diameter hoops and 3.81-cm bar mesh netting; small hoop net (SH): 1.3 m long with 4 0.51-m diameter hoops and 3.81-cm bar mesh netting; and small hoop net (SM): 1.3 m long with 4 .0.51-m diameter hoops and 2.54-cm bar mesh netting). Channel catfish were fully-recruited at 35cm total length (TL) in LH and SH configurations and 30 cm TL in the SM configuration. The SM...

Channel Catfish Movements in Relation to River Channel-Floodplain Connections

We conducted a study of channel catfish (Ictalurus punctatus) movements in the Yockanookany River, Mississippi, a river subjected to a long-reach decoupling of the river channel from its respective floodplain. We collected 40 channel catfish and surgically implanted radio-transmitters. Fish were tracked during 2 periods—March-June 1994 and November 1994-June 1995. Most fish moved ≤5 km. During elevated flows, radio-tagged fish in the river moved to or remained in the river section coupled with the floodplain. Four fish moved from the river channel into an oxbow lake when it was coupled...

Abundance and Selection of Invertebrates by Northern Bobwhite Chicks

Invertebrate density and biomass, northern bobwhite (Colinus virginianus) chick invertebrate selection, and vegetation stem density and biomass were studied in old field (OF), fertilized old field (FOF), and fertilized kobe lespedeza (FKL) (Lespedeza striata var. kobei) plots, in the summers of 1985 and 1986. Total invertebrate density and biomass were not different (P > 0.05) among treatments. Coleoptera (beetles) density and biomass were greatest (P < 0.05) in FKL plots in 1986. Coleoptera, Lepidoptera larvae, and Hemiptera were most preferred (P < 0.05) by 3-, 7-, 14-,21-, and...
