Spotted Bass Population Characteristics and Relationships with Macrohabitat Variables in the Arkansas River, Arkansas

Despite its importance to anglers, the Arkansas River spotted bass (Micropterus punctulatus) fishery has not been intensively studied or managed. Thus, spotted bass populations in the lower nine navigation pools of the Arkansas River were assessed during 2004-2005 using nighttime boatmounted electrofishing. Across years and pools, size structure measures were within acceptable ranges for black basses (mean PSDQ = 38, range 21-56; mean PSDP = 10, range 0-19). Theoretical maximum sizes generated from growth models were not large for spotted bass (mean L∞ = 395 mm TL, range 351-429 mm...

Exploring the Utility of Various Minimum-length Limits for the Largemouth Bass Fishery in the Arkansas River, Arkansas

Largemouth bass (Micropterus salmoides) on the Arkansas River have been regulated by a 381-mm minimum-length limit (MLL) regulation since 1 January 1998; however, little evaluation of this regulation has been conducted. During 2004-2005 and 2010, largemouth bass populations were sampled from throughout all navigation pools in the Arkansas River. All bass were aged using sagittal otoliths, and population metrics were calculated to conduct simulation modeling using the Fisheries Analyses and Simulation Tools (FAST) software. Composite model parameters were developed using data from all 3...

Largemouth Bass Fishery Characteristics in the Arkansas River, Arkansas

The Arkansas River largemouth bass (Micropterus salmoides) fishery has not been intensively managed or studied, especially downstream of Lake Dardanelle. Recent issues that have potentially affected the fishery necessitated a comprehensive assessment of populations throughout the entire Arkansas portion of the river. During 2004-2005, largemouth bass populations were assessed in all 11 Arkansas navigation pools of the river using boat-mounted, nighttime electrofishing. Populations were young with 94% of the individuals consisting of ages 1-4. Across years and pools, size structure...
