“…We chose to correct the RRR observations for individuals to that of the mean size of wild fish in the study. We used the size‐dependent exponent (−0.265) published by Hartman and Cox (2008), which is within the range found for most fish species of −0.20 to −0.33 (Winberg 1956). This potentially creates a propagation of errors by using a model within a model (Bartell et al.…”

ObjectiveOur objective was to compare wild and hatchery sourced Brook Trout Salvelinus fontinalis to determine the importance of source population on routine respiration rate (RRR), the major cost term in bioenergetic models.MethodsWe evaluated intraspecific variation in RRRs of one hatchery and four wild Brook Trout populations. Hatchery fish were obtained from the Bowden State Fish Hatchery in Elkins, West Virginia, and were the basis for the previously published bioenergetics model for the species. Wild fish were obtained from four headwater streams in West Virginia. Using intermittent respirometry, we measured and analyzed RRRs sequentially at 20, 16, and 12°C. Measures on hatchery fish were censored to restrict the dataset to similar sizes and temperatures as used with the wild populations. We used a suite of mixed effects models and one linear model to compare RRRs of hatchery fish with wild fish, as well as to determine whether wild populations differed.ResultWe found that the RRR of hatchery fish was double that of wild fish over the range of 12–20°C. Within the wild populations, the RRR of the Potomac drainage fish was lower than two of the three Ohio drainage populations despite all steams falling within 55 km of each other.ConclusionOur findings suggest that selective pressures at the hatchery, as well as factors that influence thermal regimes in wild populations, likely influence RRR in Brook Trout. More research is needed to identify correlates related to intraspecific variation in fish respiration rates. Most fish bioenergetics models are not based on, or calibrated to, the specific population to which they are applied. Therefore, we encourage greater efforts be expended to calibrate and validate such models in the future.

“…related oxygen consumption models have been developed for Esox lucius (Du et al, 2011), Hemibarbus maculatus (Hui et al, 2020), and Oplegnathus fasciatus (Yan et al, 2008). The relationship between oxygen consumption rate ( R ) and body mass ( W ) is an exponential function: R = aW b , where a and b are constants, with a values generally varying due to environmental conditions and fish species and b values reflecting the anisotropic growth characteristics of fish (Singer, 2006; Winberg, 1956). Various tissues that directly sustain life in fish (kidneys, brain, gills, etc.)…”

Glyptosternoid fishes are distributed in the torrent environment of alpine canyons, where they often leave the water to climb on rocky cliffs. As one of the most primitive species of glyptosternoid fishes, Euchiloglanis kishinouyei was examined in the current study to analyze its gill microstructure and respiratory ability. We first found that the oxygen consumption rate was relatively high and negatively correlated with body mass, and that the average oxygen consumption at night was higher than during the day. The asphyxiation point of E. kishinouyei (5.05 ± 0.22 g) was about 1.93 mg/L. Subsequently, the surface morphology, gross gill tissue structure and ultra‐microstructure of gill lamellae were investigated by optical microscopy and scanning electron microscopy. The gills showed an overall trend of regression, with five pairs of gill arches in each gill cavity. The adjacent gill filaments were with large gaps, and the gill lamellae were thick. The gill filaments were closely arranged on the gill arches, their folded respiratory surface was highly vascularized with no tiny crest, while there were obvious tiny crests, grooves, pits, and pores on the non‐respiratory surface. The gill lamellae were closely embedded on both sides of gill filaments, which were composed of flat epithelial cells, basement membrane, pillar cells and mucous cells. The gill total respiratory area correlated positively with body mass and length, while the gill relative respiratory area correlated negatively with body mass. We comprehensively analyzed the gill microstructure and respiratory capacity of E. kishinouyei, to provide fundamental data for the adaptive evolution of the gill structures of bimodally respiring fishes and offer insights into further study on the accessory air‐breathing function of skin.

“…Peters (1983) used data from previous studies to illustrate the linear relationship, with a slope less than one, of body mass (kg) to a standard metabolic rate (Watts), and showing most organisms adhere to this predictable pattern, if variations in thermal regulation (i.e., endotherm or ectotherm) are taken into account. This relationship also predicts that larger individuals have a proportionally lower metabolic rate than smaller individuals (see also Winberg, 1956). Using the metabolic scaling equation of Peters (1983), metabolism for a single fish weighing 20 grams is 47.44% of 20 fish weighing 1 g each.…”

Losses in freshwater fish diversity might produce a loss in important ecological services provided by fishes in particular habitats. An important gap in our understanding of ecosystem services by fishes is the influence of individuals from different size classes, which is predicted based on known ontogenetic shifts in metabolic demand and diet. I used 20 experimental stream mesocosms located at Konza Prairie Biological Station (KPBS), KS, USA, to assess the influence of fish size on ecosystem properties. Mesocosms included two macrohabitats: one riffle upstream from one pool filled with consistent pebble and gravel substrate. There were four experimental and one control treatment, each replicated four times (N = 20). I used two size classes of central stonerollers (Campostoma anomalum) and southern redbelly dace (Chrosomus erythrogaster). Five ecosystem properties were assessed: algal filament length (cm), benthic chlorophyll a (μg/cm2), benthic organic matter (g/m2), macroinvertebrate biomass (g/m2), and stream metabolism (g O2/m2/day−1). Size structure of fish populations affected some, but not all, ecosystem properties, and these effects were dependent upon species identity. Size structure of both species had effects on algal filament lengths where stonerollers of both size classes reduced algal filaments, but only small redbelly dace kept filaments short. A better understanding of the relationship between these prairie stream minnows and their small stream habitats could be useful to both predict changes in stream properties if species are lost (redbelly dace are a Species In Need of Conservation) or size structure shifts.
