“…When they enter estuaries like Chesapeake Bay they may be required to enter hypoxic zones to hunt for specific prey items. For example, common prey items for cobia [17] like blue crabs and Atlantic croaker have C crit values of 1.6-2.5 mg l −1 (23-28°C; [32]) and 1.8 mg l −1 (25-30°C; [57]), respectively. Although hypoxia tolerance of cobia significantly worsened at the end-of-century treatment (32°C), it still did not exceed 2.5 mg l −1 .…”

Cobia (Rachycentron canadum) support recreational fisheries along the US mid-and south-Atlantic states and have been recently subjected to increased fishing effort, primarily during their spawning season in coastal habitats where increasing temperatures and expanding hypoxic zones are occurring due to climate change. We therefore undertook a study to quantify the physiological abilities of cobia to withstand increases in temperature and hypoxia, including their ability to recover from exhaustive exercise. Respirometry was conducted on cobia from Chesapeake Bay to determine aerobic scope, critical oxygen saturation, ventilation volume and the time to recover from exhaustive exercise under temperature and oxygen conditions projected to be more common in inshore areas by the middle and end of this century. Cobia physiologically tolerated predicted mid-and end-of-century temperatures (28-32°C) and oxygen concentrations as low as 1.7-2.4 mg l −1 . Our results indicated cobia can withstand environmental fluctuations that occur in coastal habitats and the broad environmental conditions their prey items can tolerate. However, at these high temperatures, some cobia did suffer post-exercise mortality. It appears cobia will be able to withstand near-future climate impacts in coastal habitats like Chesapeake Bay, but as conditions worsen, catch-and-release fishing may result in higher mortality than under present conditions.

“…Shifts in the range of native seagrasses have been documented in the polyhaline region of the Bay and temperature change has been identified as the driver behind changes in distributional patterns (Richardson et al 2018). Increasing temperatures can produce cascades of varying effects on aquatic organisms, including those that impact copepod mortality (Pierson et al 2016), fish recruitment and timing based on those same zooplankton populations (Millette et al 2020), metabolic tolerance of increased temperatures for demersal species (Marcek et al 2019), and Bay habitat suitability for juvenile sandbar sharks (Crear et al 2020). These examples only scratch the surface of additional identified impacts of temperature on marine organisms not listed here; more are summarized in Najjar et al (2010).…”

Coastal environments such as the Chesapeake Bay have long been impacted by eutrophication stressors resulting from human activities, and these impacts are now being compounded by global warming trends. However, there are few studies documenting long‐term estuarine temperature change and the relative contributions of rivers, the atmosphere, and the ocean. In this study, Chesapeake Bay warming, since 1985, is quantified using a combination of cruise observations and model outputs, and the relative contributions to that warming are estimated via numerical sensitivity experiments with a watershed–estuarine modeling system. Throughout the Bay’s main stem, similar warming rates are found at the surface and bottom between the late 1980s and late 2010s (0.02 ± 0.02°C/year, mean ± 1 standard error), with elevated summer rates (0.04 ± 0.01°C/year) and lower rates of winter warming (0.01 ± 0.01°C/year). Most (~85%) of this estuarine warming is driven by atmospheric effects. The secondary influence of ocean warming increases with proximity to the Bay mouth, where it accounts for more than half of summer warming in bottom waters. Sea level rise has slightly reduced summer warming, and the influence of riverine warming has been limited to the heads of tidal tributaries. Future rates of warming in Chesapeake Bay will depend not only on global atmospheric trends, but also on regional circulation patterns in mid‐Atlantic waters, which are currently warming faster than the atmosphere.
