Abstract:

Alewife (Alosa pseudoharengus) survival from newly hatched larvae to fall young-of-the-year (YOY) was calculated using data collected in southeastern Lake Michigan, June–November 1974–82. Alewife YOY density (number per 1000 m3) was estimated from trawl catches. Larval alewife densities, derived from plankton net samples at trawling stations and from power plant entrainment samples, were averaged each year for length intervals which represented yolk-sac and post-yolk-sac larvae. Survival (ratios of YOY to larval alewife densities) varied considerably among years, but mean survival over all yea

Abstract:

The influence of prey availability and predation risk on the distribution of young-of-year (YOY) walleye (Stizostedion vitreum) was investigated by comparing species associations with the relative abundance of YOY walleye across nine habitat types using an underwater visual assessment technique. During the early demersal period (mid-June to mid-July), YOY walleye were found primarily in areas of high macrophyte cover at 25 m depth. YOY walleye abundance was positively correlated with the abundance of prey fishes at this time. YOY walleye shifted to low-cover, shallow areas during the late dem

Length of growing season and encounter rate, λ, between YOY walleye and the prey fish set the potential for growth in a particular aquatic system.

Abstract:

The growth-survival paradigm predicts that year-class strength is determined by growth-dependent mortality during the larval stage. In Atlantic mackerel Scomber scombrus, the possibility that strong growth-dependent mortality extends into the early juvenile stage has not previously been tested because of the difficulty in sampling young-of-the-year (YOY) juveniles. The present study determined the timing of the ‘endpoint’ during the early ontogeny, when growth-selective mortality decreases and recruitment is set.

Our goal was to test the hypothesis that mortality rate is negatively related to the abundance of littoral coarse woody habitat, which ranged from 3 to 1500 pieces of wood per kilometre of shoreline in these lakes.

Abstract:

This study aims to forecast U.S. inflation by using crude oil prices as a key variable. WTI crude oil price and Consumer Price Index Year-over-Year (CPI YoY) data from 2000 to 2022 are extracted to construct a time series model. The empirical analysis relies on Autoregressive Integrated Moving Average (ARIMA) model and regression to formulate forecasts based on historical patterns and error dynamics. The study finds out that compared to the automatically generated ARIMA model, using fitted values of the WTI time series model to predict CPI YoY through a multi-variable model is better. Accordin

Abstract:

Measurements of in situ food consumption and growth rates of young-of-the-year (YOY) yellow perch, Perca flavescens, indicated that extrapolations of the metabolic allometry of adult perch to larval and juvenile perch were inappropriate. YOY active metabolism had the same weight dependent slope as adults but was 4.4 times adult standard respiration. Adult active respiration is typically 1–2 times standard. YOY consumption rates were also higher than predicted from adult allometry. Model simulations demonstrate that consumption and growth dynamics of larval and juvenile fish are more sensitive

Long-term monitoring data were used to test whether the invasion of zebra mussels (Dreissena polymorpha) in the Hudson River Estuary in 1991 altered the influence of density dependence and environmental conditions on life-stage transitions, growth, and partial migration in white perch (Morone americana). During the post-invasion period (1992–2013), we estimated standing stocks of white perch eggs, yolk-sac larvae (YSL), post-yolk-sac larvae (PYSL), young-of-the-year (YOY), and adults as well as indices of YOY growth and spatial distribution.

Alosa pseudoharengus (alewife) has declined throughout New England. A factor that may be responsible for such stock reductions is urbanization of watersheds discharging into alewife nursery ponds.

The watersheds ranged from 3% to 60% urbanized land cover. YOY δ15N increased significantly in proportion to urbanized land cover on watersheds, suggesting a concrete link between watershed land cover a

The majority (92%) of sheltering salmon were young-of-the-year salmon (YOY). Of the YOY observed, 45% were sheltering, while 55% were in the water column. In comparison, only 1

The Norwegian electrical energy supply system is based on hydropower. The now deregulated energy market has led to increased use of hydropeaking production, leading to greater fluctuations in discharge and water levels below hydropower stations.

With over 300 rapid flow increases and decreases per year since 2012, it is a river subjected to frequent hydropeaking.

After large numbers of YOY yellow perch appeared in the littoral zone, walleyes fed primarily on the abundant yellow perch

Abundance and size of adult and young-of-year (YOY) frogs did not differ significantly between stocked and unstocked lakes. We also compared the wood frog population from a twelfth, fishless lake with populations from the 11 fish-bearing lakes

This model successfully predicted PU by comparison with previous estimates for yellow perch. YOY fish contributed more to limnetic nutrient cycling through excretion than older age-classes, and YOY fish could also serve as an important P sink relative to algal sinking losses.
