Comparing Precision of Otolith and Pectoral Spine Age Assessments for Black and Yellow Bullheads

SEAFWA Journal Volume 10, March 2023

Despite the broad geographical range of bullhead catfishes (Ameiurus spp.), their population vital rates have rarely been studied. Estimation of vital rates requires accurate age estimates and otoliths generally are considered to be the most accurate and precise aging structure for most fish species. However, pectoral spines of some ictalurid species have been used to generate precise age estimates of younger fish. Although previous studies have compared age estimates between otoliths and spines for large-bodied, longer-lived catfishes, there have been few comparable studies...
