Resistance of erythrocytes from Brown trout (Salmo trutta m. trutta L.) affected by ulcerative dermal necrosis syndrome In the present work we evaluated the effect of ulcerative dermal necrosis (UDN) syndrome on resistance of erythrocytes to haemolytic agents and lipid peroxidation level in the blood from brown trout (Salmo trutta m. trutta L.). Results showed that lipid peroxidation increased in erythrocytes, as evidenced by high thiobarbituric acid reactive substance (TBARS) levels. Compared to control group, the resistance of erythrocytes to haemolytic agents was significantly lower in UDN-positive fish. Besides, UDN increased the percent of hemolysated erythrocytes subjected to the hydrochloric acid, urea and hydrogen peroxide. Results showed that UDN led to an oxidative stress in erythrocytes able to induce enhanced lipid peroxidation level, as suggested by TBARS level and decrease of erythrocytes resistance to haemolytic agents.

El objetivo de este trabajo fue estudiar algunos elementos traza y mayoritarios en músculo e hígado de peces de lagos de la Patagonia Norte Cordillerana para brindar información sobre los niveles de base en relación a la distribución global de elementos, y efectos locales relacionados con la variabilidad interespecifica en un mismo ambiente y espacial en una misma especie entre las distintas cuencas. Para lo cual, en el primer caso, se compararon las concentraciones elementales en los peces cordilleranos patagónicos que incluyeron salmónidos: Salmo trutta (trucha marrón), Oncorhynchus mykiss (trucha arco iris), Salvelinus fontinalis (trucha de arroyo), un percíctido: Percichthys trucha (perca de boca chica) y un silúrido: Diplomistes viedmensis (bagre aterciopelado) con grupos taxonómicos similares de áreas remotas y con impacto antrópico de distintas regiones del mundo. En el segundo caso, se evaluó la variabilidad interespecífica de la concentración de los elementos en los lagos Nahuel Huapi y Moreno por estar próximos y conectados, y fundamentalmente por la variedad y abundancia de especies de peces. La variabilidad espacial de la composición elemental de los peces en las distintas cuencas relacionadas con diversos factores ambientales como el basamento geológico y el impacto antrópico, se evaluó en la trucha arcoíris que está ampliamente distribuida en los distintos lagos, de vertiente atlántica como el Traful, Espejo Chico, Nahuel Huapi y Moreno, y de pendiente pacífica como Guillelmo, Rivadavia y Futalaufquen.

In the past, the anadromous salmonids, Atlantic salmon (Salmo salar) and sea-trout (Salmo trutta), have formed natural populations in the river Rhine. From the beginning of the nineteenth century onwards, the greater part of the drainage area of the river has been gradually altered from a more or less rural and agricultural area, into a highly industrialised one with subsequent industrialisation, river-engineering and heavy pollution. These developments are considered to be the major cause for the disappearance of the populations of anadromous salmonid fish in the 1950s. The water quality has recovered significantly during the past 25 years. From about 1975 onwards, this process gave rise to a recovery of the anadromous trout population. Results of recent studies of the sea-trout migration pattern are presented. They reveal that nowadays these salmonids can complete their up- and downstream migrations from the North Sea to places, situated at hundreds of kilometres upward the river and vica versa. The numbers of recorded Atlantic salmon and catch locations in inland waters are presented. They show a significant increase since 1989. These phenomena can be understood as promising signs of the recovery of the Rhine aquatic ecosystem.

AbstractFollowing on from a few decades of osteological analysis this study presents an assessment of the data retrieved from human population samples provided by four early farming sites, namely Ilıpınar, Menteşe, Barcın and Aktopraklık, located in the lake basins southeast of the Sea of Marmara. It highlights various aspects of that population such as demographic data, health, trauma, and ancient people’s attitude toward death. The research aims to identify and discuss similarities and dissimilarities between the studied Neolithic settlements in this region, especially with regard to paleo-demographic data and the use of violence. With exception of a small group of burials at Aktopraklık that contrasted with regular inhumations, it seems that mortuary practices barely differed from one community to another, and transcended across regional boundaries. The use of wooden planks covering the bottom of grave pits, which were first discovered at Ilıpınar, may serve as an example. Early farmers of the eastern Marmara region suffered mostly from joint diseases and degenerative arthritis. Their life expectancy was similar for adults of both sexes, at between 25–40 years, while two of the four communities showed high infant mortality.
