“…Another fish implanted was euthanised under Schedule 1 of the Animals Scientific Procedures Act (1986) after it failed to fully recover from anaesthesia; although a post-mortem revealed no surgical complications. Individual fish were tracked from 40 to 629 days (mean 266.0 ± SD 146.7; see Gardner et al, 2013). Subsequent analysis of tracking data showed no evidence of tag expulsion and survival rates of 100% were experienced for fish that stayed within the study area in the short term, with all fish released showing upstream movements (indicative of an alive fish) for at least two months, usually substantially more, post-surgery.…”

“…Tracking results were obtained from up to twenty-six fixed (marginal, maintained at approximately mid-water depth, a metre below the surface) VR2 and VR2 W acoustic receivers (Vemco, Nova Scotia, Canada) which were positioned ∼2-3 km apart, as described by Gardner et al (2013).…”

“…Tag implantation into the peritoneal cavity is commonly used in long-term tracking studies of fishes (Lucas and Batley, 1996) and regularly used for cyprinid species (e.g. Lucas and Batley, 1996;Huber and Kirchhofer, 1998;Lyons and Lucas, 2002;Winter and Fredrich, 2003;Fredrich et al, 2003;Kuliskova et al, 2009;Gardner et al, 2013). Such telemetry studies commonly rely on three assumptions: (1) fish condition and mortality are not altered by the tagging transmitter implantation in largemouth bass Micropterus salmoides (L.) (Mesing and Wicker, 1986) and dace Leuciscus leuciscus (L.) (Clough and Beaumont, 1998), but without a suitable control population in the watercourse, it is difficult to ascribe this behaviour as a direct effect of the capture, handling and surgical procedure.…”

“…The study had other primary objectives (see Gardner et al, 2013Gardner et al, , 2015. However, it also presented the opportunity to analyse the shortterm effects of capture, handling and tagging on the behaviour of the bream via a comparison of the movements of the two groups of bream.…”

Differences in movements of northern pike inhabiting rivers with contrasting flow regimes

et al. 2016

Little is known about the effect of short‐term flow changes on the movement of northern pike (Esox lucius L.). We conducted a comparative study in two rivers with different flow regimes (i.e. one regulated and one unregulated) to evaluate the extent to which adult northern pike movement is influenced by short‐term river flow conditions. Data on northern pike hourly movement were collected in northeastern Ontario on 40 individuals in the Mississagi River, a river subjected to extreme daily flow variations associated with hydro‐electric operations (i.e. hydropeaking), and the Aubinadong River, an unregulated river. Using manual tracking by radio‐telemetry, we found that northern pike moved at a higher rate in the river subjected to short‐term changes in river flow than in the unregulated river. Results also show that the relationship between movement of northern pike and flow can vary among rivers. In the Mississagi River, flow had a significant positive effect on northern pike activity, while the effect of flow in the Aubinadong River depended on water temperature. Moreover, fish in the Mississagi River utilized a restricted river section and travelled more laterally in comparison to fish inhabiting the Aubinadong River, where longer upstream‐downstream movements were more common. The present study contributes to our understanding of the effects of short‐term changes in flow on fish movement. This constitutes the first step towards assessing the effect of flow on fish habitat use, and eventually developing flow management strategies to mitigate impacts on fish.

Assessments of patterns of animal movements are important for understanding their spatial ecology. Geostatistical models of stable isotope (SI) landscapes (isoscapes) provide a complementary tool to telemetry for assessing and predicting animal movements, but are rarely applied to riverine species. Often single‐isotope gradients in freshwater environments are insufficiently variable to provide high isoscape resolution at relatively fine spatial scales. This is potentially overcome using dual‐isotope assignment procedures, and thus, the aim here was to apply single (δ13C) and dual (δ13C and δ15N) isoscapes to assigning riverine fish to origin and predicting their movements. Using the River Bure, England, as the study system, the foraging locations of a small‐bodied lowland river fish (roach Rutilus rutilus) of low vagility were predicted using their SI data and those of a common prey item (amphipods). These foraging locations were then compared to their capture locations, with the distance between these being their predicted displacement distance. The results indicated significant enrichment of δ13C and δ15N with distance downstream in roach fin tissue and amphipods; roach bivariate isotopic niches were spatially variable, with no niche overlap between upstream and downstream river reaches. Furthermore, the dual‐isoscape assignment procedure resulted in the lowest predicted displacement distances for roach, therefore enhancing model performance. The dual‐isoscape approach was then applied to determining the predicted displacement distance of individual common bream Abramis brama, a larger, more vagile species, with these data then compared against the subsequent spatial extent of their movements recorded by acoustic telemetry. When using a high probability density threshold for isotope assignment, the predicted displacement distance of common bream was a significant predictor of the spatial extent of their subsequent movements recorded by acoustic telemetry, although it was less able to predict the direction of displacement. This first probabilistic assignment to origin for riverine species using a dual‐isotope isoscape technique demonstrated that where the required spatial resolution of animal movements in freshwater is moderately broad (5–10 km), dual‐isotope isoscapes can provide a reliable alternative or complementary method to telemetry.
