“…Perch and pikeperch were less mobile when temperature dropped. This decline in perch activity in relation with water temperature was already observed in various hydrosystems (Craig, 1977;Eriksson, 1978;Karas & Thoresson, 1992;Huusko et al, 1996;Neuman et al, 1996;Jacobsen et al, 2002) but for pikeperch, our observations differed from those of Koed et al (2000) and Jepsen et al (1999) who observed a low significant correlation between the total distance moved and water temperature. In contrast, the drop in water temperature observed between the beginning of summer and the middle of winter did not appear to clearly affect pike activity showing some species differences.…”

-The aquatic ecosystem structuration in human influenced environment, is closely dependent of the associated uses, which are generally fluctuant. We conducted an extended field monitoring on a reservoir under water level fluctuations (WLF), in order to study the responses of fish fauna to changes in environmental conditions. The study design was based on a monitoring of fish behaviour by telemetry in a reservoir with a particular attention to the littoral zone because of its front line position during WLF. The results of this study, which was conducted on the Bariousses reservoir, located on the Vézère river (Corrèze, France), are summarized in this article. The study revealed that WLF induced a temporal variability in the littoral zone surface. In addition, we observed a gradual decline in structural complexity of littoral habitats with a tendency towards homogenisation (dominance of fine substrates and absence of vegetation) in relation with the drop in water level. Behavioural individual responses of pikeperch, perch and pike were highly variable in relation to environmental fluctuations. Temperature and photoperiod were the two main parameters controlling fish activity and spatial distribution. Water level affected part of fish assemblage: some individuals were more mobile and left the littoral zone when inshore habitats were less complex (low water level).Keywords -reservoir; littoral habitat; fish; water level fluctuations; acoustic telemetry.Résumé -Le fonctionnement des milieux, aquatiques soumis à des pressions anthropiques, est étroitement dépendant des usages générant des fluctuations de l'environnement des communautés biologiques. Nous avons mené une étude sur une retenue soumise à des fluctuations du niveau de l'eau (WLF), afin d'étudier les réponses de l'ichtyofaune aux changements des conditions environnementales. Un suivi du comportement des poissons par télémétrie acoustique a été mené avec une attention particulière portée à la zone littorale car elle est fortement soumise aux WLF.

“…Consequently, restocking programs for this species have been implemented in several countries (e.g., Finland, Poland, and Iran) (Bartley and Rana 1998; Steenfeldt et al 2015). These programs, as well as other research projects, have begun analyzing the effectiveness of restocking this species along with investigating little known aspects of pikeperch biology, such as spawning migrations (Koed et al 2000; Koed et al 2002). Essential data are acquired from observations of tagged fish.…”

“…Adult pikeperch are most frequently tagged with TTs that are inserted into the body cavity through a small incision, while the antenna is directed through an opening located just above it. The incision is closed with two or three silk sutures depending on the size of the incision and the size of the fish being tagged (Koed et al 2000; Horký et al 2006). Other methods of implantation incision closure, such as tissue adhesive or leaving the incision open, have been investigated in other fish species (Baras and Jeandrain 1998; Cooke et al 2011).…”

The aim of this work was to determine the impact of surgically implanted telemetry transmitters (TTs) on the growth, survival, hematological and biochemical indexes, and wound healing in juvenile pikeperch (Sander lucioperca) (body weight 60–90 g). Two incision suturing methods were used—silk sutures (experiment I—group ST) or tissue adhesive (experiment II—group GT). After tagging, the fish were held in a recirculating system for 35 days. No statistically significant differences were noted in the growth or condition indexes analyzed among the fish tagged with TT compared with those from the control groups (untagged). Substantial individual variability was noted, however, in the parameters examined in both the control and tagged groups. Among the hematological indexes, statistically significant differences were only noted in experiment I. Lower values of mean corpuscular volume and mean corpuscular hemoglobin were noted in group ST. Among the biochemical parameters, creatinine was statistically significantly threefold lower, magnesium and alkaline phosphatase (ALP) levels were lower, and ammonia levels were higher in group ST than in the control group. In experiment II, significant differences were only noted for ALP. Tissue adhesive was the superior and more effective method for closing the incision after TT implantation in juvenile pikeperch. This type of suturing facilitated faster healing, and it had less of an impact on juvenile pikeperch welfare.

“…Migration between two freshwater habitats is known as "potamodromy" and is less well studied (but see Northcote 1997). Potamodromous fishes may migrate from lakes to streams, as is the case with roach, common bream (Abramis brama (L., 1758)), and white bream (Blicca bjoerkna (L., 1758)) , or may make migrations to different areas of river habitats, as do predatory pikeperch (Sander lucioperca (L., 1758)) (Koed et al 2000). Finally, fish that migrate between marine habitats are known as "oceanodromous" migrants.…”

Animal migration is an amazing phenomenon that has fascinated humans for long. Many freshwater fishes also show remarkable migrations, whereof the spectacular mass migrations of salmonids from the spawning streams are the most well known and well studied. However, recent studies have shown that migration occurs in a range of freshwater fish taxa from many different habitats. In this review we focus on the causes and consequences of migration in freshwater fishes. We start with an introduction of concepts and categories of migration, and then address the evolutionary causes that drive individuals to make these migratory journeys. The basis for the decision of an individual fish to migrate or stay resident is an evaluation of the costs and benefits of different strategies to maximize its lifetime reproductive effort. We provide examples by discussing our own work on the causes behind seasonal migration in a cyprinid fish, roach (Rutilus rutilus (L., 1758)), within this framework. We then highlight different adaptations that allow fish to migrate over sometimes vast journeys across space, including capacity for orientation, osmoregulation, and efficient energy expenditure. Following this we consider the consequences of migration in freshwater fish from ecological, evolutionary, and conservation perspectives, and finally, we detail some of the recent developments in the methodologies used to collect data on fish migration and how these could be used in future research.Key words: fish migration, seasonal, evolution, consequences, cyprinids.Résumé : L'étonnant phénomène des migrations animales fascine les humains depuis belle lurette. De remarquables migrations caractérisent de nombreux poissons d'eau douce, les migrations massives des salmonidés à partir de leur cours d'eau d'origine étant les plus connues et les plus étudiées. Cela dit, des études récentes ont démontré l'existence de migrations chez divers taxons de poissons dulcicoles d'habitats nombreux et variés. Dans la présente synthèse, nous nous penchons sur les causes et conséquences de la migration chez les poissons dulcicoles. Nous abordons en premier lieu les concepts importants et les catégories de migration, puis examinons les causes évolutionnaires qui amènent des individus à accomplir ces déplacements migratoires. La décision d'un poisson donné de migrer ou de demeurer en place repose sur une évaluation des coûts et avantages de différentes stratégies visant à optimiser son effort de reproduction durant sa durée de vie. Nous présentons des exemples basés sur nos propres travaux sur les causes de la migration saisonnière chez un poisson cyprinidé, le gardon (Rutilus rutilus (L., 1758)), dans ce cadre. Nous décrivons ensuite différentes adaptations qui permettent dans certains cas à des poissons de migrer sur de grandes distances, dont une capacité d'orientation, l'osmorégulation et l'efficience des dépenses énergétiques. Nous examinons ensuite les conséquences de la migration chez les poissons dulcicoles des points de vue écologique, évolutio...
