“…Likewise, lakes have previously been viewed as isolated ecosystems (Forbes, ; Hansson et al, ). Many lakes are, however, interconnected through inlet and outlet streams, allowing ecologically significant fish movements between lakes (Daniels, Morse, Sutherland, Bombard, & Boylen, ), with potential consequences for trophic interactions and ecosystem stability. The importance of fish movement between lakes within river drainage systems is already acknowledged, based on knowledge about fish biogeography (Olden, Jackson, & Peres‐Neto, ) and population genetics (Stepien, Murphy, Lohner, Sepulveda‐Villet, & Haponski, ).…”

“…The importance of fish movement between lakes within river drainage systems is already acknowledged, based on knowledge about fish biogeography (Olden, Jackson, & Peres-Neto, 2001) and population genetics (Stepien, Murphy, Lohner, Sepulveda-Villet, & Haponski, 2009). Despite several available methods, such as markrecapture (Daniels et al, 2008), otolith microchemistry (Whitledge, Johnson, & Martinez, 2006) and biotelemetry (Cooke et al, 2004), documentation of individual movement between lakes is still relatively rare (Daniels et al, 2008). Previous studies of individual fish movement between lakes (Bajer, Chizinski, & Sorensen, 2011;Daniels et al, 2008;Diana, Hanchin, & Popoff, 2015;Huuskonen, Haakana, Leskelä, & Piironen, 2012;Parsons & Reed, 2005;Pearson, 2002;Rasmussen, Heisey, Gilbert, King, & Hewett, 2002;Weeks & Hansen, 2009) have paid little attention to distinguishing between movement types.…”

The recent focus on a common movement ecology paradigm has increased awareness about the importance of distinguishing different movement patterns for understanding their specific impact on animal ecology and evolution. One specific form of movement is nomadism, where animals move between habitats in an arrhythmic fashion. Although not yet described in detail for freshwater fish, nomadism between lakes within drainage systems could affect local lake food webs in an otherwise unpredictable fashion. In this study, we used passive telemetry to describe inter‐lake movements of 1,280 individually tagged adult benthivorous bream (Abramis brama) over nine contiguous years in a drainage system with two paired lakes. The movements can best be described as partial nomadism, where a part of the population is neither resident nor migratory, but instead moves between lakes in a variable, arrhythmic fashion, often with long residency in one lake before moving to the other. We found extensive between‐year variation in the proportion and direction of bream moving, with higher movement propensity being partly associated with lower somatic condition. Notably, movements out of lakes were significantly more in direction of the neighbouring lake than away from the paired lakes, suggesting that at least direction was not random. Since bream are important ecosystem engineers, fluctuating densities of adult bream could affect ecological stability in lakes. Our study suggests that fish populations in interconnected lakes within drainages should not be treated as isolated units, and we discuss this in relation to lake ecology and the importance for lake ecosystem management.

First, stocking of triploids reduces the potential risk of out‐migrating fish colonizing adjacent waters and threatening the persistence of native salmonids via competition or introgressive hybridization.…”

Anglers value alpine lakes as providing a scenic, backcountry fishing experience that is seldom found in other fisheries. However, trout introduced into alpine lakes often pose a risk to native salmonids in downstream habitats by establishing source populations in headwater locations. Although the stocking of sterile triploid trout can reduce this risk, poststocking performance should be equivalent to that of diploid fish before fisheries managers and anglers consider triploid stocking to be ideal. In this study, three different mechanical pressure treatments were tested to create mixed‐sex triploid Westslope Cutthroat Trout Oncorhynchus clarkii lewisi; at 65,500.19 kPa (9,500 psi) applied for 5 min at 300 Celsius‐minutes after fertilization, triploid induction rates were 100%, and egg survival to eye‐up was only 8% lower than that for diploids. Fry were stocked into 51 alpine lakes (25 with triploids and 26 with diploids), and fish were sampled 3 years later. Gill‐net catch rates, growth, and condition did not differ between stocked diploid and triploid fish. General linear models revealed that test fish were larger and in better condition in lakes with fewer total fish (indicating a density‐dependent influence on growth and condition) and were also in better condition in lower‐elevation lakes containing a higher percentage of shallow habitat. Ploidy level was not included in the most plausible model for any of the response variables. Our results indicate that triploid Westslope Cutthroat Trout can easily be created by using pressure treatment of fertilized eggs and appear to be a suitable alternative to diploids in alpine lake stocking programs. Our study suggests that the use of triploid Westslope Cutthroat Trout in alpine lakes similar to those we studied would prevent hybridization with native salmonids in adjacent habitats without reducing the abundance, size, or condition of fish available to anglers in the lakes where they are stocked.

“…Lake connectivity can also be a driver of fish assemblage patterns. While lakes are often considered isolated units, fishes have been shown to move between connected water bodies (Daniels et al , ). Spatial autocorrelation resulting from fish movement between lakes was controlled in the analysis by the inclusion of spatial terms.…”

ABSTRACT1. Changes to native fish assemblages in lakes are commonly associated with introduced predatory fishes. How fish assemblages change as multiple predatory species are introduced is not well understood.2. This study investigated the relationship between the presence of introduced large-bodied predatory fishes (largemouth bass Micropterus salmoides, pike Esox lucius, rock bass Ambloplites rupestris, smallmouth bass Micropterus dolomieu, walleye Sander vitreus) and the composition of native fish assemblages in littoral areas of 40 lakes in Algonquin Provincial Park, Ontario, Canada. Fish assemblages were compared across lakes of different predator composition, and within lakes before and after recent predator invasions.3. The presence of an introduced predator was associated with significantly different native fish assemblages across lakes, after controlling for environmental and spatial variables.4. Native fish assemblages did not significantly vary across lakes with more than one predator species. Furthermore, while declines in native species richness over time were observed in a number of lakes, these were not associated with introductions of additional predators.5. Several small-bodied species (brook stickleback Culea inconstans, fathead minnow Pimephales promelas, finescale dace Chrosomus neogaeus, and northern redbelly dace Chrosomus eos) consistently showed strong negative correlations with predator presence.6. The results suggest that predatory fish introductions alter native fish assemblages and that this impact is consistent regardless of the number of predatory species introduced.
