Effective Tandem Hoop Net Sampling Effort For Evaluation Of Channel Catfish Populations In Reservoirs, Philip B. Malone
Effective Tandem Hoop Net Sampling Effort For Evaluation Of Channel Catfish Populations In Reservoirs, Philip B. Malone
Theses and Dissertations from 2016
Channel Catfish Ictalurus punctatus have an important role in Arkansas’s commercial and recreational fisheries. This importance promoted sampling strategy investigations for obtaining information that assist with future management decisions. My study focused on determining effective sampling effort and sample size requirements needed for detecting changes in relative abundance within Channel Catfish populations, and explored relationships between catch per unit effort (CPUE) and reservoir habitat characteristics. My study was conducted during the spring of 2014 in six reservoirs (Lake Nimrod, Lake Overcup, Lake Catherine, De Queen Lake, Lake Erling, and Lake Columbia). General stock assessments consisting of length frequency distributions, growth …
Movement, Habitat Use, Reproduction, And Commercial Harvest Of Paddlefish In Lake Dardanelle, Arkansas, Adam Geik
Theses and Dissertations from 2016
Paddlefish Polyodon spathula are a valuable commercial species throughout much of their range including Lake Dardanelle, one of the most important commercial paddlefish fisheries in Arkansas. While fecundity, mortality, and age and growth of paddlefish stocks in Lake Dardanelle have been assessed previously, information on their movements, habitat utilization, and commercial harvest rates is lacking. To help fill this information gap, 39 paddlefish were tracked a minimum of once per month from October 2014 through September 2015. Habitat selection was determined for eight macrohabitat types and four bathymetric habitat types by comparing percent usage to percent availability. Four high-use (≥10%) …
