“…Rates of exact agreement between reading pairs for otolith age estimates were generally lower than those reported for other fish species but rates of agreement within one year were similar to values reported in published studies (Welch et al 1993;Isermann et al 2003). Rates of exact agreement between reading pairs and agreement within one year for pectoral fin ray age estimates were within the ranges of values reported in published studies for other fish species (Sikstrom 1983;Welch et al 1993;Rien and Beamesderfer 1994;Spiegel et al 2010). Several studies have reported an effect of reader experience on precision of otolith or fin ray age estimates (Campana and Moksness 1991;Ross et al 2005;Brenden et al 2006), whereas other studies found no difference with experience level (Howland et al 2004;Vandergoot et al 2008).…”

“…Precision of age estimates from rainbow smelt (Osmerus mordax; Walsh et al 2008) pectoral fin rays and muskellunge (Esox masquinongy; Brenden et al 2006) pelvic fin rays were similar to pectoral fin ray age estimates for M. dolomieu. However, age estimates derived from pectoral fin rays were more precise for carpsuckers, (Carpiodes spp., Spiegel et al 2010), pallid sturgeon (Scaphirhynchus albus; Hurley et al 2004), and white sturgeon (Acipenser transmontanus; Rien and Beamesderfer 1994) compared to pectoral fin ray age estimates in this study. Failure to identify the first annulus is a common occurrence when aging fish with pectoral fin rays due to central lumen expansion and obliteration of the first annulus (Buckmeier et al 2002).…”

Journal of Freshwater Ecology, 2013 Vol. 28, No. 2, 199-210, http://dx.doi.org/10.1080/02705060.2012 Using pectoral fin rays as a non-lethal aging structure for smallmouth bass: precision with otolith age estimates and the importance of reader experience We evaluated the potential utility of pectoral fin rays as non-lethal aging structures for smallmouth bass (Micropterus dolomieu). We compared age estimates among three reading pairs and against sectioned sagittal otolith age estimates for precision. Reading pair bias was not detected, although the highest rates of age estimate agreement occurred between reading pairs with high and moderate aging experience. Precision of otolith and fin ray age estimates were equivalent based on between-structure comparisons of average percent error and coefficient of variation. However, fin rays underestimated fish age compared to otoliths for older fish, especially when aged by less-experienced readers. Pectoral fin rays may provide a non-lethal alternative to otoliths for aging smallmouth bass, particularly for younger fish (age 4) or when experienced readers conduct aging. Additional evaluations of fin rays as smallmouth bass aging structures are needed, including validation using known-age fish and documentation of consistent annulus formation throughout a fish's life.

“…Catostomids were identified, measured to the nearest millimeter (total length), and weighed to the nearest gram. The left marginal pectoral fin ray was removed by cutting just proximal to the point of where the fin ray joined the body wall (Koch et al, 2008;Spiegel et al, 2010). After drying, fin rays were mounted in epoxy following the methods provided in the study by Koch and Quist (2007).…”

Catostomids are among the most widespread and ecologically important groups of fishes in North America, particularly in large river systems. Despite their importance, little information is available on their population demographics and even less is known about factors influencing their population dynamics. The objectives of this study were to describe annual mortality, recruitment variation, and growth of eight catostomid species, and to evaluate the effects of discharge and temperature on year‐class strength and growth in Iowa rivers. Catostomids were sampled from 3‐km reaches in four nonwadable rivers during June–August 2009. Northern hogsucker, Hypentelium nigricans, golden redhorse, Moxostoma erythrurum, and shorthead redhorse, M. macrolepidotum, typically lived 6–8 years, had very stable recruitment, and had high total annual mortality (i.e., 40–60%). Golden redhorse exhibited the fastest growth of all species. Growth of northern hogsucker and shorthead redhorse was intermediate to the other catostomids. Highfin carpsucker, Carpiodes velifer, quillback, Carpiodes cyprinus, and white sucker, Catostomus commersonii, had high growth rates, low mortality (i.e., 25–30%), and relatively stable recruitment. River carpsucker, Carpiodes carpio, and silver redhorse, M. anisurum, had higher maximum ages (up to age 11), slower growth, lower total annual mortality (20–25%), and higher recruitment variability than the other species. Neither discharge nor temperature was strongly related to recruitment of catostomids. In contrast, several interesting patterns were observed with regard to growth. Species (e.g., carpsuckers, Carpiodes spp.) that typically consume prey items most common in fine substrates (e.g., chironomids) had higher growth rates in reaches dominated by sand and silt substrate. Species (e.g., northern hogsucker) that consume prey associated with large substrates (e.g., plecopterans) had much faster growth in reaches with a high proportion of rocky substrates. Temperature was weakly related to growth of catostomids; however, discharge explained a substantial amount of the variation in growth of nearly all species. Results of this study provide important information on the autecology of catostomids that can be used for comparison among species and systems. These data also suggest that connection of rivers with their floodplain is an important feature for catostomids in temperate river systems. Published in 2011 by John Wiley & Sons, Ltd.

“…Knowledge of fish length and age estimates from other readers were not shared between readers during the age estimation process to avoid bias. In addition to the presumptive number of annuli, readers also assigned a confidence rating to each structure (Fitzgerald et al 1997, Koch et al 2008, Spiegel et al 2010. Confidence ratings were used as a measure of the readability of individual structures.…”
