Evaluation of Largemouth Bass Supplemental Stocking on a Virginia Coastal River

SEAFWA Journal Volume 4, March 2017

Coastal rivers can support quality largemouth bass (Micropterus salmoides) fishing, but recruitment failure and habitat availability can influence population size and structure because of the dynamic nature of these systems. Stocking success in coastal river systems has been rarely evaluated. is study examined stocking success of oxytetracycline (OTC) marked F1 intergrade Florida (M.s. oridanus) and northern (M.s. salmoides) fingerling largemouth bass in the tidal Chickahominy River, Virginia. Fish were stocked at a density of 62 fish ha-1 in spring 2006 (mean TL = 54 mm) and 2007 (mean TL...

Exploitation and Length Limit Evaluation of Largemouth Bass in Three Georgia Small Impoundments

SEAFWA Journal Volume 1, March 2014

Recent studies on largemouth bass (Micropterus salmoides) fisheries indicate fishing mortality has declined significantly due to voluntary catch-and-release practices by anglers. We evaluated the relative abundance, growth, mortality, and exploitation of largemouth bass in three Georgia small impoundments. To assess exploitation, 100 largemouth bass were tagged during spring 2010 in Lake Lindsay Grace and Hugh M. Gillis Public Fishing Area and during spring 2011 in Dodge County Public Fishing Area. Monetary rewards for tag returns were either US$5 or $105 per fish, and these values were...

Comparison of Diploid and Triploid Largemouth Bass Growth and Maturation in Puerto Rico

Fisheries Outstanding Technical Paper
SEAFWA Journal Volume 1, March 2014

Triploid largemouth bass may have potential in sport fish management and in food fish production as a means to eliminate reproduction, which would, in turn, potentially increase somatic growth. To examine this potential, four cohorts of diploid and triploid largemouth bass were produced over a 10 &#45 yr period and tagged intramuscularly with coded wire tags. Bass were stocked into Lucchetti Reservoir, Puerto Rico, and recaptured during subsequent sampling events. Growth rates, condition (relative weight, Wr), and reproductive investment (gonadosomatic index, GSI) were compared for...

Ageing Precision and Error Analysis of Whole-view and Sectioned Otoliths in Largemouth Bass and Spotted Bass

SEAFWA Journal Volume 1, March 2014

The objectives of this study were to quantify ageing precision for largemouth bass (Micropterus salmoides) and spotted bass (M. punctulatus), and to evaluate the effect of ageing errors on the estimation of common fisheries metrics. Sagittal otoliths were extracted from 2164 largemouth bass and 738 spotted bass collected from throughout the Arkansas River, Arkansas. Largemouth bass collections occurred during 2004, 2005, and 2010; spotted bass collections were limited to 2004 and 2005. Annuli were counted by two independent readers from digital images of each whole otolith. For individuals...

A Comparison of a Fixed vs. Stratified Random Sampling Design for Electrofishing Largemouth Bass in Oklahoma

SEAFWA Journal Volume 1, March 2014

Two sampling designs were compared to evaluate Oklahoma's standardized sampling procedures for electrofishing largemouth bass (Micropterus salmoides) in reservoirs. Historical subjectively-chosen fixed sites were sampled along with random sites stratified by habitat category (good, fair, and poor) at four reservoirs in central Oklahoma. The stratified categories were determined by a composite of the shape/structure of the bottom, substrate type, and type of cover available in 0.5-km transects. Using the stratified random design, three of the four reservoirs showed significantly different (...
