“…Additionally, precision of age estimates from M. dolomieu otoliths was similar to that of other species such as largemouth bass (Micropterus salmoides; Long and Fisher 2001), spotted bass (Micropterus punctulatus; Long and Fisher 2001), and striped bass (Morone saxatilis; Welch et al 1993). However, some studies have indicated far better precision of age estimates using otoliths (e.g., white bass Morone chrysops, Soupir et al 1997, and channel catfish Ictalurus punctatus, Michaletz et al 2009). Annuli formation in otoliths of smallmouth bass has been validated (Heidinger and Clodfelter 1987) indicating that annuli are accrued consistently throughout the aging process.…”

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.

“…Reader agreement for ages compared between scales and otoliths was high (>80%) for black crappie, Pomoxis nigromaculatus (Lesueur), and white bass, Morone chrysops (Rafinesque), less than 6–7 years old from South Dakota, USA (Kruse, Guy & Willis 1993; Soupir, Blackwell & Brown 1997). However, Soupir et al. (1997) found annuli on white bass scales were difficult to interpret after age 6.…”

Largemouth bass, Micropterus salmoides (Lacepe`de), smallmouth bass, Micropterus dolomieu Lacepe`de, and yellow perch, Perca flavescens (Mitchill), were collected from the Hudson River, New York, USA, to compare the precision of age estimates derived from scales and otoliths. Similar procedures were used to compare otolith and spine ages from brown bullhead, Ameiurus nebulosus (Lesueur). Overall percent agreement between readers ranged from 91% to 98% for otoliths compared with 38% to 67% for scales and spines. Disagreement rates associated with scales and spines increased as fish grew older. Average percent error between readers was about an order of magnitude higher for scales and spines than for otoliths. Ages estimated from scales and spines progressively decreased as age increased based on otolith examination. The use of scales and spines to age largemouth bass, smallmouth bass, yellow perch and brown bullheads from the northeastern US was less precise and will likely lead to underestimation of age of larger and older fish.

“…We avoided unreliable aging structures because the accuracy of the DD assignment depended on the accuracy of age estimates (see next section). We assigned reliability to different aging structures using a combination of expert opinion (Campbell and Babaluk 1979;Graeb et al 2010;Schneider 2001;Soupir et al 1997;Trippel and Harvey 1991). For example, we assumed that only age-0 fish were accurately aged in the field and that only walleye ≤age-5 were accurately aged using scales.…”

Degree-days (DD) are an increasingly popular method for explaining variation in fish growth and development. By including a base temperature (T o ) the DD formula limits calculations to temperatures that are relevant to growth. However, our review of growth studies shows multiple T o values in use for a given fish species. To determine how T o affects the ability of DD to explain within-population growth variation, we first show that the ability of DD to describe a growing season is robust to low values of T o . We then analyze immature length data from eight species and 85 water bodies in North America to show that there is a broad range of T o values that effectively explain growth variation. Based on these results, we argue that precise T o estimates are unwarranted for most single-population studies and recommend standard T o values (0, 5, 10, 15°C). Standardization facilitates comparative studies and promotes the use of DD in future research. To this end, we provide equations for converting annual DD at a given T o to annual DD at a standard T o . Résumé :Les degrés-jours (DJ) constituent une méthode de plus en plus usitée pour expliquer les variations associées à la croissance et au développement des poissons. L'incorporation d'une température de base (T o ) dans la formule des DJ limite les calculs aux températures pertinentes pour la croissance. Un examen des études sur la croissance indique toutefois que de multiples valeurs de T o sont utilisées pour des espèces de poissons données. Afin de déterminer l'incidence de T o sur l'adéquation des DJ pour expliquer les variations de croissance au sein d'une population, nous démontrons d'abord l'adéquation des DJ pour décrire une période de croissance jusqu'à de faibles valeurs de T o . Nous analysons ensuite des données sur la longueur de poissons immatures pour huit espèces et 85 plans d'eau en Amérique du Nord pour démontrer qu'il existe une grande fourchette de valeurs de T o qui permettent d'expliquer adéquatement les variations de croissance. À la lumière de ces résultats, nous postulons que des estimations précises de T o ne sont pas nécessaires pour la plupart des études sur des populations individuelles et recommandons l'utilisation de valeurs de T o normalisées (0, 5, 10, 15°C). Une telle normalisation facilite les études comparatives et favorisera l'utilisation de DJ dans des travaux futurs. Nous présentons à cet effet des équations pour la conversion de DJ annuels pour une T o quelconque en DJ annuels pour une T o normalisée. [Traduit par la Rédaction]
