“…These are all processes associated with enhanced cell degradation and catabolism. Since fish in this study were of rather uniform size, age is unlikely to be a determinant of MA size and frequency; this is further corroborated by the lack of a relationship between MAs and fish size (Brown et al 2009;Purchase 2004;Purchase et al 2005). A positive relationship between hepatic MAs and Hg tissue concentrations was reported for a variety of fish species, including pike (Esox lucius) with muscle Hg ranging from 0.21 to 0.82 μg g −1 wet wt (Meinelt et al 1997), spotted gar (Lepisosteus oculatus) (0.01-1.1 μg g −1 wet wt in muscle, Barst et al 2011), and trahira (Hoplias malabaricus) (1.45 μg g −1 wet wt in muscle, Mela et al 2007).…”

Mercury (Hg) contamination is a global issue due to its anthropogenic release, long-range transport, and deposition in remote areas. In Kejimkujik National Park and National Historic Site, Nova Scotia, Canada, high concentrations of total mercury (THg) were found in tissues of yellow perch (Perca flavescens). The aim of this study was to evaluate a possible relationship between THg concentrations and the morphology of perch liver as a main site of metal storage and toxicity. Yellow perch were sampled from five lakes known to contain fish representing a wide range in Hg concentrations in fall 2013. The ultrastructure of hepatocytes and the distribution of Hg within the liver parenchyma were analyzed by transmission electron microscopy (TEM) and electron energy loss spectrometry (EELS). The relative area of macrophage aggregates (MAs) in the liver was determined using image analysis software and fluorescence microscopy. No relation between general health indicators (Fulton's condition index) and THg was observed. In line with this, TEM examination of the liver ultrastructure revealed no prominent pathologies related to THg accumulation. However, a morphological parameter that appeared to increase with muscle THg was the relative area of MAs in the liver. The hepatic lysosomes appeared to be enlarged in samples with the highest THg concentrations. Interestingly, EELS analysis revealed that the MAs and hepatic lysosomes contained Hg.

“…More productive ecosystems can support higher trophic levels (Oksanen et al 1981;Vander Zanden et al 1999) and ontogenetic dietary shifts in more productive ecosystems would also be expected from the ecosystem size hypothesis. Similarly, at least some individual species tend to be larger in large lakes (Alm 1946;Griffiths 1994;Ylikarjula et al 1999;Purchase et al 2005) and to feed at higher trophic levels (perch (Perca fluviatilis) (Alm 1946), arctic charr (Salvelinus alpinus) (Griffiths, unpublished), lake trout (Salvelinus namaycush) (Martin & Olver 1980)), consistent with the ecosystem size hypothesis.…”

Body size distributions in North American freshwater fish: small‐scale factors and synthesis

The ecosystem size/trophic structure hypothesis predicts that the shape of body size distributions will change with ecosystem size because of increases in the relative importance of large, predatory, species. I test the hypothesis by examining the statistical moments, as measures of shape, of species body size distributions of North American freshwater fish assemblages in lakes. Species lists, coupled with dietary and body size information, are used to document the patterns. Body size distributions in small lakes are unimodal and right‐skewed, but distributions become more symmetrical and bimodal in large ecosystems. In small lakes, body sizes are generally small and fish trophic levels low, but size and trophic level increase up to lake volumes of about 0.001 km3, and change little in larger lakes. Adding trophic level to the analysis greatly improves the variance explained by the body size–lake size relation. The conclusions of Griffiths (2012, Global Ecology & Biogeography 21: 383‐392), that postglacial recolonisation and evolutionary change are important determinants of body size distributions at regional and larger scales, are combined with those of this study. Mean body size in local assemblages of lake‐dwelling species is larger than in regional and continental ones. Overall, body size distributions are affected by processes operating at a variety of spatial and temporal scales, with the type, size and duration of the ecosystem probably playing a central role by influencing the proportions of vagile and predatory species, the species which dominate the large size mode.

The degree-day (DD) is a method of describing the thermal opportunity for growth and development and is becoming increasingly popular when comparing fish growth over large spatial scales (e.g., counter-gradient growth). Temperatures too cold to permit growth are excluded in the DD equation by incorporating a lower temperature threshold (T o ). However, there is no convention for choosing T o , and unknown is the effect of an incorrect T o on how growth is perceived. We simulate data to demonstrate how an incorrect T o may lead to differences in temperature-corrected growth rates among populations. These differences increase with the error in T o and the thermal range among simulated populations. We then show the same relationships in an analysis of length-at-age data from 81 walleye (Sander vitreus) populations in North America. Together, our results demonstrate that differences in temperature-corrected growth rates among populations can be a statistical artifact rather than a biological phenomenon, especially when populations are distributed over a large thermal gradient. Résumé :La méthode des degrés-jour (DJ), utilisée pour décrire les possibilités de croissance et de développement selon la température, est de plus en plus employée pour comparer la croissance des poissons sur de grandes étendues (p. ex. croissance à contre-gradient). Les températures trop basses pour permettre la croissance sont exclues de l'équation des DJ en incorporant un seuil de température minimum (T o ). Il n'existe toutefois aucune convention sur le choix de la valeur de T o , et l'effet d'une T o incorrecte sur la perception de la croissance est inconnu. Nous simulons des données afin de démontrer comment une T o incorrecte peut mener à des différences entre populations sur le plan des taux de croissance corrigés pour la température. Plus l'erreur associée à T o et la fourchette de températures pour les populations simulées sont grandes, plus ces différences sont importantes. Nous démontrons ensuite l'existence des mêmes relations dans une analyse de données de longueur selon l'âge pour 81 populations de dorés jaunes (Sander vitreus) en Amérique du Nord. Collectivement, nos résultats démontrent que des différences entre populations sur le plan des taux de croissance corrigés pour la température peuvent être des artefacts statistiques plutôt que le produit d'un phénomène biologique, particulièrement dans le cas de populations réparties le long d'un important gradient thermique.
