“…We use the term "credible" in reference to the abundance of evidence that indicates Blue Sucker lapillus otoliths likely reflect accurate annuli, but we refrain from referring to the otoliths as truly "accurate" in the absence of validation. We found that Blue Sucker otoliths were the most structurally consistent of any of the structures that we investigated, with presumed annuli being regularly spaced and immediately recognizable and consistent with age-validated catostomid lapilli (Terwilliger et al 2010;Bettinger and Crane 2011;Lackmann et al 2019). The tight correlation between Blue Sucker whole lapillus mass and otolith age assignment (R 2 = 0.89; Figure 3) is similar to the correlation found between Bigmouth Buffalo whole lapillus mass and validated age (A. R. Lackmann, personal observation) and indicates catostomid otoliths experience consistent growth with age despite asymptotic growth in other tissues.…”

“…Lapillus otoliths are validated for aging a variety of catostomid species, including the White Sucker (Thompson and Beckman 1995), Lost River Sucker Deltistes luxatus, Shortnose Sucker Chasmistes brevirostris (Hoff et al 1997;Terwilliger et al 2010), Notchlip Redhorse Moxostoma collapsum, Brassy Jumprock Moxostoma sp. (Bettinger and Crane 2011), and Bigmouth Buffalo (Lackmann et al 2019). Otoliths had higher precision than other aging structures in Razorback Suckers Xyrauchen texanus (McCarthy and Minckley 1987), Bluehead Suckers Catostomus discobolus, Flannelmouth Suckers Catostomus latipinnis, White Suckers, Roundtail Chub Gila robusta, Creek Chub Semotilus atromaculatus, White Sucker × Bluehead Sucker hybrids, and White Sucker × Flannelmouth Sucker hybrids (Quist et al 2007).…”

“…The authors suggested that the absence of bias among these three structures was due in part to the predominance of young fish in the study; interpretation of results is also limited by the small sample size ( n = 9). Until now, no study explored otolith age estimates for a robust sample of Blue Suckers, despite thin‐sectioned otoliths being validated or recommended for aging numerous other catostomid species (McCarthy and Minckley 1987; Thompson and Beckman 1995; Hoff et al 1997; Quist et al 2007; Terwilliger et al 2010; Bettinger and Crane 2011; Lackmann et al 2019). Furthermore, no previous study compared the ages estimated from Blue Sucker otoliths to the ages estimated from scales and pectoral fin rays (the hard structures historically used for aging this species) or from opercles (a hard structure that some advocate for aging catostomids) (Scoppettone et al 1986; McCarthy and Minckley 1987; Burr and Mayden 1999; Peterson et al 1999).…”

Comparison of Four Hard Structures Including Otoliths for Estimating Age in Blue Suckers

The Blue Sucker Cycleptus elongatus is an imperiled North American catostomid in need of management and protection. No hard structures are validated for aging this species, but past studies focused on somatic structures such as fin rays and scales. Calculated parameters (mortality, recruitment, growth) that inform management decisions are directly influenced by the accuracy and precision of the hard structure used to estimate age. We identify the most precise and credible structure with which to age Blue Suckers while also completing the first in-depth investigation of their otoliths. We collected Blue Suckers (n = 168) from the lower Wabash River and compared ages estimated from scales, opercles, pectoral fin rays, and lapillus otoliths but were unsuccessful in estimating ages from cleithra. We identified structure bias between all structures and found scales (n = 67; maximum = 11 years, mean = 8.2 years) and opercles (n = 65; maximum = 15 years, mean = 8.3 years) to be substantially less precise than pectoral fin rays and lapillus otoliths. We found that otoliths (n = 128; maximum = 42 years, mean = 13.5 years) were more precise than fin rays (n = 167; maximum = 20 years, mean = 9.6 years) and yielded a much higher range of ages. We could not identify any range of ages or total lengths in which (nonlethal) fin ray age could be accurately corrected to (lethal) otolith age. Thin-sectioned otoliths are the gold standard for aging most fishes, including numerous age-validated catostomids, and the credibility of Blue Sucker otolith age estimates was additionally supported by a strong correlation between whole lapillus mass and estimated age (R 2 = 0.89). Overall, evidence indicates that Blue Sucker lapillus otoliths yield more precise and credible age estimates than other hard structures.

“…Otolith annulus counts have been documented as a reliable age estimator for several species of suckers (Catostomidae) in the genus Catostomus (Sylvester and Berry 2006;Quist et al 2007;Bettinger and Crane 2011). Aging methods were validated for White Suckers by Thompson and Beckman (1995), using edge analysis (Beckman and Wilson 1995).…”

The purpose of this study was to document the time of formation for the first two otolith annuli for White Sucker Catostomus commersoni. Young‐of‐the‐year and age‐1 individuals were sampled monthly from a population in the White River drainage of the Missouri Ozarks. The formation of a single annual opaque region during the months of June–September of the first 2 years of life was documented using edge analysis, whereby the progression of otolith annulus formation is followed throughout the year in the population. The documentation that the first annulus was formed within the first 6 months following birth provides for more accurate and precise age estimations than previously available for this species.

“…Validation of otoliths as an ageing structure has been completed for many species (Hales and Belk 1992;Secor et al 1995;Clayton and Maceina 1999;Bettinger and Crane 2011;Blackwell and Kaufman 2012). Although no study has evaluated ageing accuracy for white perch, otoliths have been validated for the congeneric striped bass (Heidinger and Clodfelter 1987;Secor et al 1995).…”

Accurately ageing fish is essential for fisheries managers when calculating population dynamics for a particular species. Despite being a popular sport fish in its native range with a large expanding non-native range, otoliths of white perch Morone americana have not been validated. White perch were collected monthly during 2015-2016 from Sooner Lake, Oklahoma to remove sagittal otoliths to validate annulus formation. Marginal increment analysis verified a single annulus formed once yearly in otoliths of white perch and formation was complete by April or June, depending on fish age. Because descriptions of population characteristics of invasive white perch in Oklahoma are limited, the dynamics of the Sooner Lake population was described. The Sooner Lake white perch population is characterized by rapid growth rates, average longevity and mortality rates, high proportional size distribution and below average condition. The Sooner Lake population is a non-stunted population, which has not previously been documented in Oklahoma. White perch form a single opaque band once annually in sagittal otoliths, validating this structure as an ageing method for this species. This study expands on the existing literature on invasive white perch population characteristics and serves as a reference to which other Oklahoma populations can be compared.
