Abstract:
Fish assemblages in small lakes ([Formula: see text]50 ha) in central Ontario were characterized to determine the impact of smallmouth bass (Micropterus dolomieu) predation and habitat complexity on the structure of littoral zone fish assemblages. Data were collected employing minnow traps and visual assessment. Although species richness did not differ between lakes with and without smallmouth bass, species composition and relative abundance did differ. We identified two distinct fish assemblage types: one characterized by small-bodied species, mainly cyprinids, and a second by large-bodied centrarchid species, e.g., smallmouth bass. Smallmouth bass appear to reduce abundance, alter habitat use, and extirpate many small-bodied species such as brook stickleback (Culaea inconstans), fathead minnow (Pimephales promelas), pearl dace (Margariscus margarita), and Phoxinus spp.

Abstract:
Ecosystem modelling has predicted that fishing for western rock lobster Panulirus cygnus in deep water (50–80m) habitats will result in increased abundance of their macroinvertebrate prey, which would, in turn, support greater production of small-bodied invertivore fish species. To investigate the potential ecosystem effects of rock lobster fishing, a targeted fisheries closure was proposed in deep water habitats along the coast of Western Australia. Data on small-bodied invertivore fish abundance, from baited video, were used to investigate differences across habitats and simulate the likely power of any study to detect change. In general, small-bodied invertivore fish were more abundant at shallower macroalgae-dominated sites, whereas the most abundant single species, the western king wrasse Coris auricularis, was abundant across all habitats and sites. Power simulation of a mixed-model before–after–control–impact (BACI) design found that a 40–50% decrease in either Coris auricularis or small-bodied invertivore fish in general would be very likely to be detected (power ~0.8). Based on the power simulation, we suggest a general sampling design to investigate change before and after the establishment of the fishery closure and make suggestions for further ecological studies to investigate the predicted ecosystem effects of rock lobster fishing.

Abstract:
Abstract The utility of using fish held in cages for investigating the potential effects of industrial and municipal effluents has been demonstrated. These types of exposures are able to control the influence of some confounding factors and also provide a measure of certainty with regard to exposure. However, Canada's current Environmental Effects Monitoring (EEM) Program for metal mines does not accept caged fish as a viable alternative for use in place of wild fish surveys. Concerns appear to be focused on the confounding influences of confinement stress on typical EEM endpoints. Confinement stress may be reduced in smaller-bodied fish relative to larger fish, increasing the relevance of their use for EEM. A standardized technique for deploying small-bodied fish in cages that may be useful for EEM programs is described.

Abstract:
Fish species are commonly used as experimental models in the laboratory. DNA is routinely collected from these animals to permit identification of their genotype. The current standard procedure to sample DNA is fin clipping, which involves anaesthetising individuals and removing a portion of the caudal fin. While fin clipping reliably generates good quality DNA samples for downstream applications, there is evidence that it can alter health and welfare, leading to infection and impacting on the fish’s behaviour. This in turn can result in greater variation in the data collected. In a recent study we adapted a skin swabbing protocol to collect DNA from small-bodied fish, including sticklebacks and zebrafish, without the use of anaesthetics or sharp instruments. A rayon-tipped swab was used to collect mucus from the flank of the fish, which was then used for DNA extraction. We subsequently demonstrated that compared to fin clipping, skin swabbing triggered fewer changes in stress axis activation and behaviour. We also found that data collected from fish that had been swabbed were less variable than data from fish that had been fin clipped, potentially allowing smaller sample sizes in experimental groups after using this technique, and thereby reducing animal use. Here we provide a detailed protocol explaining how to collect DNA samples from small laboratory fish using skin swabs.

Abstract:
Fishways are a common tool for mitigating the effects of habitat fragmentation on fish, but their utility in low-gradient, sand-bed rivers of the Great Plains is not well studied. The Lincoln Street Fishway on the Arkansas River became operational in 2015 and was built specifically to pass small-bodied threatened fishes. We compared current and historical surveys up- and downstream of the barrier to test the effect of the fishway on community structure and conducted tagging experiments to test the ability of fishes to move into and through the fishway. Differences in community structure and species richness between communities up- and downstream of the dam were reduced following construction of the fishway. Surveys within the fishway revealed that 74% of species from the sampled community were using the fishway. Fishes marked with visible implant elastomer downstream of the dam were recaptured in the fishway, qualitatively showing that small-bodied fishes could move into and upstream within the fishway. We further quantified upstream movement for three species of small-bodied minnow tagged with passive integrated transponder tags during manipulations of flows through the fishway. Our results illustrate the potential for fishways to mitigate the effects of habitat fragmentation on fishes in sand-bed rivers.

Abstract:
Estuarine ecosystems present a dynamic and often biologically challenging marine environment. Resident and migratory fish occupying these environments must cope with a multitude of variations associated with physiochemical characteristics, interspecies interactions, environmental degradation and variable feed availability. Using the yellow-eyed mullet Aldrichetta forsteri as an exemplar of many other small-bodied, estuarine-inhabiting fish, we sought to assess the suitability of an array of different tag types in tank-based experiments. The survival consequences of wild capture, handling and tagging procedures were then investigated using condition and reflex impairment criteria and simulated release. It was determined that T-bar and passive integrated transponder tags were suitable tag types, but that tagging fish smaller than 50g (~170mm) was detrimental to survival. Using a ‘low-impact’ trap design improved post-capture tagging and survival compared with an alternative capture method. In combination, the possibility of using small-bodied fish for tag–recapture studies is demonstrated and the utilisation of comparable fish for investigations into estuarine population dynamics and ecosystem interactions is advocated.

Abstract:
Abstract Under the Canadian Fisheries Act, pulp and paper mills and metal mines must conduct a cyclical monitoring program for potential environmental effects that includes a fish survey. Study designs for the fish survey have been evolving over the past few years, and there has been increased emphasis on the use of small-bodied fish species. Increasing concerns about the potential impacts of sampling programs on the fish populations in smaller receiving waters have led us to develop non-lethal sampling methodologies that will satisfy the information requirements for the environmental effects monitoring program. This manuscript outlines the use of a non-lethal sampling program to collect information on age distributions, growth rates, reproductive performance and fish condition in populations of slimy sculpin inhabiting forested and agricultural sections of a small New Brunswick river.

Abstract:
<i>Abstract.</i>—We document a simple electrofishing-only monitoring program for assessing fish assemblages across large spatial extents. First, we demonstrate the justification for using only electrofishing for the monitoring. Second, we demonstrate the usefulness of having a well-designed surveillance-monitoring program in place to demonstrate the effect of landscape disturbances. Implementing electrofishing alone means that multiple sites can be sampled in a single day and there is no need to return to clear nets or traps within a sampling site. Whereas electrofishing alone does not return full species lists within sampled sites, we demonstrate that when data are aggregated up to the watershed or catchment extent, more than 90% of species are included. Analyses that do not require a census of species, such as bioassessment of river health can be readily carried out using electrofishing data. The Murray–Darling basin, Australia, was sampled with the recommended large-extent electrofishing program between 2004 and 2012, a period that saw the region subjected to large-scale variations in river flow levels spatially and temporally. We fit generalized additive models to the electrofishing data in conjunction with river flow data to document large-extent relationships between fish species occurrence and relative flow levels for the previous 3 d, 3 months, or 3 years. We found that several small-bodied species, Eastern Mosquitofish <i>Gambusia holbrooki</i>, Flathead Gudgeon <i>Philypnodon grandiceps</i>, and Australian Smelt <i>Retropinna semoni</i>, were more likely to be collected when conditions were drier in the past 3 d to 3 months, whereas common medium and large-bodied species were less likely to be collected when flow was lower over the previous 3 months to 3 years.

Abstract:
<em>Abstract.</em>—The Bullseye Snakehead <em>Channa marulius </em>is an air-breathing, large-bodied freshwater fish native to Southeast Asia. All <em>Channa </em>species are listed as prohibited (no live possession) in Florida and are high priority for Early Detection Rapid Response (EDRR). This species was illegally introduced to southeast Florida waters and first reported in 2000. Bullseye Snakehead are now abundant in six major canal systems and are slowly spreading into interconnected canals. The laboratory derived lower lethal temperature of ≤10°C indicates the potential range of Bullseye Snakehead is limited to peninsular Florida. Bullseye Snakehead opportunistically feed on a wide variety of organisms but primarily consume small fishes, crustaceans, and insects. No measurable negative effects on native fishes in urban canals have been associated with the presence of Bullseye Snakehead to date. The Florida Fish and Wildlife Conservation Commission (FWC) is concerned these successful invaders may spread into natural areas including Everglades National Park where their potential adverse impacts are unknown. The FWC conducts standardized electrofishing, promotes consumptive use at outreach events, and conducts EDRR as management strategies for Bullseye Snakehead. The illegal presence of Bullseye Snakehead in Florida is undesirable and less problematic to native fish communities in urban canals than anticipated, but their potential impact in natural areas is unclear.

Abstract:
<em>Abstract</em>.—The Hanjiang River is the largest tributary of the Yangtze River and contains Danjiangkou Dam, which forms Danjiangkou Reservoir in the middle and upper reaches of the river. During the past 50 years, fisheries resources have changed significantly in the middle and lower Hanjiang River and in Danjiangkou Reservoir. Spawning grounds for major carps and other commercially important fishes have disappeared. Downstream of Danjiangkou Dam, total egg quantity spawned by major carps and other commercially im portant fishes have decreased while similar measures from small-bodied fishes have increased. Important commercial fishes have experienced delayed spawning times and decreased growth. Overall catches of commercial fishes have decreased downstream of the dam, though increased upstream. Some exotic fishes captured in the Danjiangkou Reservoir were likely escapees from cage-culture fish farms in the reservoir or from land-based fish farms around the reservoir. Changes in fisheries resources were presumed related to reservoir management strategies, which produced a narrower range of year-round water temperatures and caused decreases in seasonal water flow variation downstream, overfishing, and eutrophication in the reservoir. To implement a national water diversion policy in central China, the height of the Danjiangkou Dam was increased 15 m in 2012, which significantly increased the impoundment area of the Danjiangkou Reservoir at the end of 2014. Further changes in fisheries resources can be expected in the future. At the present time, management and conservation strategies for fisheries resources need to be developed to ensure future fisheries sustainability for both the Hanjiang River and the Danjiangkou Reservoir.
