The highly productive fisheries of Alaska are located in seas projected to experience strong global change, including rapid transitions temperature and ocean acidification-driven changes pH other chemical parameters. Many the marine organisms that most intensely affected by acidification (OA) contribute substantially state's commercial traditional subsistence way life. Prior studies OA's potential impacts on human communities have focused only possible direct economic losses from specific...
Humpback whales (Megaptera novaeangliae) are one of several baleen whale species in the Northwest Atlantic that coexist with vessel traffic and anthropogenic noise. Passive acoustic monitoring strategies can be used conservation management, but first step toward understanding behavior a is good description its repertoire. Digital tags (DTAGs) were placed on humpback Stellwagen Bank National Marine Sanctuary to record describe non-song sounds being produced conjunction foraging activities....
In the past decade, much progress has been made in real-time passive acoustic monitoring of marine mammal occurrence and distribution from autonomous platforms (e.g., gliders, floats, buoys), but current systems focus primarily on a single call type produced by species, often location. A hardware software system was developed to detect, classify, report 14 types 4 species baleen whales real time ocean gliders. During 3-week deployment central Gulf Maine late November early December 2012, two...
Ocean acidification (OA) research seeks to understand how marine ecosystems and global elemental cycles will respond changes in seawater carbonate chemistry combination with other environmental perturbations such as warming, eutrophication, deoxygenation. Here, we discuss the effectiveness limitations of current approaches used address this goal. A diverse is essential decipher consequences OA organisms, communities, ecosystems. Consequently, benefits each approach must be considered...
Winter mortality plays a significant role in the dynamics of some temperate fish populations and has been shown to be size-dependent for species, but not others. Our objective was determine how winter affects recruitment Hudson River striped bass (Morone saxatilis). We used catch-per-unit-effort data from three separate surveys targeting young-of-the-year (YOY), overwintering, age 1 bass. Age abundance negatively correlated with severity winter. In contrast, 0 abundance, suggesting that...

Abstract Hurst, T. P., Fernandez, E. R., and Mathis, J. 2013. Effects of ocean acidification on hatch size larval growth walleye pollock (Theragra chalcogramma). – ICES Journal Marine Science, 70: 812–822. Rising atmospheric concentrations CO2 are predicted to decrease the pH high-latitude oceans by 0.3–0.5 units 2100. Because their limited capacity for ion exchange, embryos larvae marine fishes be more sensitive elevated than juveniles adults. Eggs chalcogramma) were incubated across a...
Attaching bio-telemetry or -logging devices (‘tags’) to marine animals for research and monitoring adds drag streamlined bodies, thus affecting posture, swimming gaits energy balance. These costs have never been measured in free-swimming cetaceans. To examine the effect of from a tag on metabolic rate, cost transport behavior, four captive male dolphins (Tursiops truncatus) were trained swim set course, either non-tagged (n=7) fitted with (DTAG2; n=12), surface exclusively flow-through...
Decision makers are increasingly requesting that environmental and climate drivers be included in stock assessments subsequent projections provide managers with advice on the consequences of applying harvest control rules. Another key direction assessment science is to capture full range uncertainty (model, process, estimation). However, multiple sources rarely accounted for when conducting based drivers. We describe a framework allows structural model (in structure population dynamics which...
Survival rates during the first winter of life are strongly size dependent and variable in many temperate fish populations. Starvation is often implicated as cause size-dependent first-winter mortality, interannual variation energy accumulation allocation between growth storage a likely source variability. We examined these processes young-of-the-year Hudson River striped bass Morone saxatilis, which known to experience size-selective mortality deficit. Neutral-lipid lean-tissue masses were...
Fish larvae hatch asynchronously from egg batches despite experiencing a common environment during their development. The consequences for growth and survival of early late hatching were examined in pre-feeding Pacific cod under varying temperatures (i.e. 0–8°C) the laboratory. As expected, time-to-first variation time-to-hatch negatively correlated with temperature. Larvae successfully hatched 0°C treatment, but rates poorer at this temperature relative to other treatments. Size-at-hatch...
Abstract The role of behavior, especially vertical migration, is recognized as a critical component realistic models larval fish dispersion. Unfortunately, our understanding these behaviors lags well behind ability to construct three‐dimensional flow‐field models. Previous field studies behavior Pacific cod ( Gadus macrocephalus ) were limited small, preflexion stages (≤11 mm SL) in narrow range thermal conditions. To develop more complete picture we examined the effects ontogeny,...
Pacific cod (Gadus macrocephalus) is an economically and ecologically important species in the southeastern Bering Sea Aleutian Islands, yet little known about spawning dynamics of these regions. To address this knowledge gap, we applied a gross anatomical maturity key for to describe temporal spatial patterns reproductive status over three winter seasons: 2005, 2006, 2007. Maturity female was assessed by fishery observers during sampling commercial catches used construct maps showing...
The match–mismatch hypothesis (MMH) predicts that marine fish larvae will have their highest rate of growth and survival when they overlap with prey. However, Pacific cod ( Gadus macrocephalus ) other gadids continue to thrive in the Bering Sea despite delayed prey production resulting from warming loss sea ice. In this study, we examined how temperature mediates under varying conditions. Cod were reared at two temperatures (3 °C 8 °C) exposed one five different food treatments over a 6-week...
Abstract The rapid decline in Pacific cod ( Gadus macrocephalus , Gadidae) biomass following multiple Gulf of Alaska marine heatwaves (2014–2016 and 2019) may be one the most dramatic documented changes a sustainably managed fishery. As such, fisheries managers are exploring new recruitment paradigms for under novel environmental conditions. In this review, we address challenges managing forecasting populations Eastern where thermal habitats early life stages undergoing varying rates change...
ABSTRACT Environmental DNA (eDNA) has significant potential to improve the efficiency of biological sampling and detect species that pose challenges for traditional methods. However, a key obstacle in utilizing eDNA data ecosystem management is uncertainty surrounding ability estimate abundance or biomass multiple simultaneously. In this study, we use experimental trials with known biomasses explore feasibility (1) estimating proportions from metabarcoding (2) absolute concentrations by...
We examined the role of salinity, body size, and energetic state in determining low temperature tolerance young-of-the-year (YOY) striped bass (Morone saxatilis) used this information to map optimal overwintering habitat Hudson River estuary. A long-term experiment compared survival at 15 ppt 30 ppt. In additional experiments, winter-acclimated fish were exposed declines (2.3°C·day 1 1°C·week ) salinities from 0 35 Highest temperatures was consistently observed intermediate salinities....
