    Notes: The inland silverside, Menidia beryllina (Cope), is an annual zooplanktivore that occurs in estuarine and freshwater habitats along the Atlantic and Gulf of Mexico coasts and drainages of the United States. Experiments were conducted at 25 ± 1°C to quantify the relationship between mean dry weight (WD) and rates of energy gain from food consumption (C), and energy losses as a result of respiration (R) and ammonia excretion (E) during routine activity and feeding by groups of fish. The absorption efficiency of ingested food energy (A) was also quantified. Rates of C, E, and R increased with WD by factors (b in the equation y = aWDb) equal to 0.462, 0.667, and 0.784, respectively. Mean (±SE) rates of energy loss during feeding were 1.6 ± 0.1 (R) and 3.4 ± 0.6 (E) times greater than those for unfed fish. Absorption efficiency was independent of WD and estimated to be 89% of C. From these measurements, the surplus energy available for growth and activity (G) and growth efficiency (K1) were estimated. Over the range in sizes of juveniles and adults (5–500 mg WD), predicted G and K1 values decreased from 7.42 to 0.20 J mg fish−1 day−1 and 63 to 21%, respectively. Measured and predicted bioenergetic parameters are discussed within an ecological context for a northern population of this species.

    Notes: The mean rate of oxygen consumption (routine respiration rate, RR, mg O2 fish−1 h−1), measured for individual or small groups of haddock Melanogrammus aeglefinus(3–12 cm standard length, LS) maintained for 5 days within flow-through respiratory chambers at four different temperatures, increased with increasing dry mass (MD). The relationship between RR and MD was allometric (RR = α Mb) with b values of 0·631, 0·606, 0·655 and 0·650 at 5·0, 8·0, 12·0 and 15·0° C, respectively. The effect of temperature (T) and MD on mean RR was described by 〈inlineGraphic alt="inline image" href="urn:x-wiley:00221112:JFB633:JFB_633_mu1" location="equation/JFB_633_mu1.gif"/〉 indicating a Q10 of 2·27 between 5 and 15° C. Juvenile haddock routine metabolic scope, calculated as the ratio of the mean of highest and lowest deciles of RR measured in each chamber, significantly decreased with temperature such that the routine scope at 15° C was half that at 5° C. The cost of feeding (RSDA) was c. 3% of consumed food energy, a value half that found for larger gadoid juveniles and adults.

    Inter-individual differences in rates of routine energy loss and growth in young-of-the-year juvenile Atlantic cod (2004)

    Notes: Inter-individual differences in rates of routine (non-feeding) metabolism and growth were evaluated in young-of-the-year (YOY) juvenile Atlantic cod Gadus morhua. Rates of O2 consumption, CO2 production and ammonia (TAN) excretion were measured in 64, 25–43 mm standard length (LS) YOY growing at different rates (0·27–0·47 mm day−1) in a common rearing tank. Parameter rates (y) increased allometrically (y = a·Mb) with increasing body mass (M) with b-values for O2 production, CO2 consumption and TAN excretion equal to 0·81, 0·89 and 0·56, respectively. In some cases, residuals from these regressions were significantly negatively correlated to fish growth rate. In no cases did residuals of parameter rates increase with increasing growth rate. These data suggest that, during unfed periods, relatively fast-growing fish were more metabolically efficient than slower-growing fish from the same cohort. The fish condition factor, derived from 〈inlineGraphic alt="inline image" href="urn:x-wiley:00221112:JFB366:JFB_366_mu1" location="equation/JFB_366_mu1.gif"/〉, also significantly decreased with increasing growth rate. Results indicated differences in both the rates of routine energy loss and the patterns of growth allocation among YOY Atlantic cod. Since these physiological attributes were positively correlated with growth rate, they may be indicative of ‘survivors’ in field populations.

    Effects of temperature on the feeding and growth of the larvae of the invasive ctenophore Mnemiopsis leidyi (2015)
    Oxford University Press
    Details
    Publication Date: 2015-09-22
    Description: Carbon-specific prey clearance and ingestion rates of 1.5-mm tentaculate larvae of the ctenophore Mnemiopsis leidyi increased linearly between 6 and 25°C but declined between 25 and 30°C. Both absolute (length) and carbon-specific growth rate increased linearly with increasing temperature. The latter was 0.87 d –1 at 25°C. Extremely low or negative growth rates observed at 6 and 30°C help define the thermal limits to population growth of this successful biological invader.

    Thermal windows supporting survival of the earliest life stages of Baltic herring (Clupea harengus) (2012)
    Oxford University Press

    Publication Date: 2012-04-10
    Description: Peck, M. A., Kanstinger, P., Holste, L., and Martin, M. 2012. Thermal windows supporting survival of the earliest life stages of Baltic herring ( Clupea harengus ). – ICES Journal of Marine Science, 69: 529–536. Projecting climate-driven changes in marine systems will require knowledge on how thermal windows affect the vital rates of key species. To examine the potential, direct effect of climate-driven warming on southwest Baltic herring, we quantified the survival, development, and biochemical condition of embryos (eggs and yolk-sac larvae) at ten temperatures between 2.9 and 21.7°C. Viable hatch was highest from 7 to 13°C, 〈20% at 2.9°C and 0% at 21.7°C. Between 5 and 19°C, increasing temperature ( T ) decreased the time to 50% hatch ( H t , h,): H t = 4461.9 x T – 1.24 ( r 2 = 0.98, p 〈 0.0001). Using degree-days [°d = T (°C) x age (d)] could normalize some (but not all) thermal effects. Most hatching occurred 90–120°d post-fertilization, unfed larvae lost 0.33 µg dry mass ( DM ) °d –1 , larvae did not survive 〉160°d post-hatch. RNA–DNA ratios rapidly decreased between 50 and 80°d post-hatch, whereas DNA x DM –1 increased throughout the yolk-sac phase and likely provides a stronger indicator of irreversible starvation. The critical, "mixed feeding" stage is likely 60–100°d post-hatch. The broad thermal tolerance of herring embryos makes "direct", negative effects of warming unlikely; however, a lack of common methods among studies makes it difficult to project how climate warming will affect embryos of different fish populations and species.

    Predation control of zooplankton dynamics: a review of observations and models (2014)

    Publication Date: 2014-01-22
    Description: Daewel, U., Hjøllo, S. S., Huret, M., Ji, R., Maar, M., Niiranen, S., Travers-Trolet, M., Peck, M. A., van de Wolfshaar, K. E. 2014. Predation control of zooplankton dynamics: a review of observations and models. – ICES Journal of Marine Science, 71: 254–271. We performed a literature review to examine to what degree the zooplankton dynamics in different regional marine ecosystems across the Atlantic Ocean is driven by predation mortality and how the latter is addressed in available modelling approaches. In general, we found that predation on zooplankton plays an important role in all the six considered ecosystems, but the impacts are differently strong and occur at different spatial and temporal scales. In ecosystems with extreme environmental conditions (e.g. low temperature, ice cover, large seasonal amplitudes) and low species diversity, the overall impact of top-down processes on zooplankton dynamics is stronger than for ecosystems having moderate environmental conditions and high species diversity. In those ecosystems, predation mortality was found to structure the zooplankton mainly on local spatial and seasonal time scales. Modelling methods used to parameterize zooplankton mortality range from simplified approaches with fixed mortality rates to complex coupled multispecies models. The applicability of a specific method depends on both the observed state of the ecosystem and the spatial and temporal scales considered. Modelling constraints such as parameter uncertainties and computational costs need to be balanced with the ecosystem-specific demand for a consistent, spatial-temporal dynamic implementation of predation mortality on the zooplankton compartment.

    Publication Date: 2013-12-12
    Description: Peck, M. A., Neuenfeldt, S., Essington, T. E., Trenkel, V. M., Takasuka, A., Gislason, H., Dickey-Collas, M., Andersen, K. H., Ravn-Jonsen, L., Vestergaard, N., Kvamsdal, S., Gårdmark, A., Link, J., and Rice, J. Forage Fish Interactions: a symposium on "Creating the tools for ecosystem-based management of marine resources". – ICES Journal of Marine Science, 71: . Forage fish (FF) have a unique position within marine foodwebs and the development of sustainable harvest strategies for FF will be a critical step in advancing and implementing the broader, ecosystem-based management of marine systems. In all, 70 scientists from 16 nations gathered for a symposium on 12–14 November 2012 that was designed to address three key questions regarding the effective management of FF and their ecosystems: (i) how do environmental factors and predator–prey interactions drive the productivity and distribution of FF stocks across ecosystems worldwide, (ii) what are the economic and ecological costs and benefits of different FF management strategies, and (iii) do commonalities exist across ecosystems in terms of the effective management of FF exploitation?

    Forage fish, their fisheries, and their predators: who drives whom? (2013)

    Details
    Publication Date: 2013-12-12
    Description: Engelhard, G. H., Peck, M. A., Rindorf, A., Smout, S. C., van Deurs, M., Raab, K., Andersen, K. H., Garthe, S., Lauerburg, R. A. M., Scott, F., Brunel, T., Aarts, G., van Kooten, T., and Dickey-Collas, M. Forage fish, their fisheries, and their predators: who drives whom? – ICES Journal of Marine Science, 71: . The North Sea has a diverse forage fish assemblage, including herring, targeted for human consumption; sandeel, sprat, and Norway pout, exploited by industrial fisheries; and some sardine and anchovy, supporting small-scale fisheries. All show large abundance fluctuations, impacting on fisheries and predators. We review field, laboratory, and modelling studies to investigate the drivers of this complex system of forage fish. Climate clearly influences forage fish productivity; however, any single-species considerations of the influence of climate might fail if strong interactions between forage fish exist, as in the North Sea. Sandeel appears to be the most important prey forage fish. Seabirds are most dependent on forage fish, due to specialized diet and distributional constraints (breeding colonies). Other than fisheries, key predators of forage fish are a few piscivorous fish species including saithe, whiting, mackerel, and horse-mackerel, exploited in turn by fisheries; seabirds and seals have a more modest impact. Size-based foodweb modelling suggests that reducing fishing mortality may not necessarily lead to larger stocks of piscivorous fish, especially if their early life stages compete with forage fish for zooplankton resources. In complex systems, changes in the impact of fisheries on forage fish may have potentially complex (and perhaps unanticipated) consequences on other commercially and/or ecologically important species.
