“…Differences in swimming performance are indicative of variation in the general health and energetic status of fish (Plaut 2001). Thus, overwinter prey assemblages have the potential to affect energy stores of fish, indirectly affecting spring foraging, predator avoidance, and thus chance of survival.…”

“…Swimming performance post-winter would be a sensitive and ecologically relevant indicator of the effects of overwinter prey assemblage, and would permit inferences about variation in endogenous energy levels. Fish that emerge from the winter in better condition and with enhanced swimming performance would likely be more efficient at foraging and evading predators (Plaut 2001). …”

SynopsisWe compared survival, growth, and swimming performance of two size classes of age-0 largemouth bass, Micropterus salmoides, in the spring after being fed diets of bluegill, Lepomis macrochirus, fathead minnows, Pimephales promelas, or invertebrate prey during the winter. Regardless of prey assemblage, survival was uniformly high and independent of size. Length, wet-and dry-mass, and condition was also similar among treatments for both size classes. However, variation in individual performance differed, with the lowest variability in growth occurring among small age-0 largemouth bass in the invertebrate only treatment. Absolute and length corrected swimming speeds of largemouth bass were highest for invertebrate prey assemblages, intermediate for fathead minnow prey, and lowest for bluegill prey. The patterns in growth and spring swimming performance likely reflect the varied nutritive quality of different prey, the ability of largemouth bass to capture different prey, and competition with the piscine prey.

“…In contrast, unhealthy fish and poorly prepared smolts have ionoregulatory disturbances at fatigue and repeat swimming performance is reduced by up to 33 per cent [55,56]. Therefore, exercise capacity is used as a tool to assess physical condition that is thought to have ecological relevance [59] and therefore may be a useful indicator of ecological fitness [13]. It is not surprising that at some point salmon louse will impair swimming performance; however, whether this impairment is seen at ecologically relevant levels of infection is of primary interest.…”

Pink salmon, Oncorhynchus gorbuscha, are the most abundant wild salmon species and are thought of as an indicator of ecosystem health. The salmon louse, Lepeophtheirus salmonis, is endemic to pink salmon habitat but these ectoparasites have been implicated in reducing local pink salmon populations in the Broughton Archipelago, British Columbia. This allegation arose largely because juvenile pink salmon migrate past commercial open net salmon farms, which are known to incubate the salmon louse. Juvenile pink salmon are thought to be especially sensitive to this ectoparasite because they enter the sea at such a small size (approx. 0.2 g). Here, we describe how 'no effect' thresholds for salmon louse sublethal impacts on juvenile pink salmon were determined using physiological principles. These data were accepted by environmental managers and are being used to minimize the impact of salmon aquaculture on wild pink salmon populations.
