“…We found an increasing trend in mean year-end CGDDs over time, which could reflect the warming of Chesapeake Bay waters due to climate change. This corresponds with many long-term records that show that water temperature has increased along the Atlantic coast (Kerr et al 2009) and in the Chesapeake Bay (Najjar et al 2010). The Chesapeake Bay already has experienced a decrease in the extent of winter ice cover compared with 50 years ago (Boesch 2008).…”

Effects of Temperature on Age‐0 Atlantic Menhaden Growth in Chesapeake Bay

et al. 2014

Atlantic Menhaden Brevoortia tyrannus is an economically and ecologically important forage fish in the western Atlantic Ocean. In the Chesapeake Bay, its recruitment has been low since the late 1980s, prompting questions on how environmental factors may affect its productivity. Growth is an important component of production, but causes of spatial and temporal variability in growth of age‐0 Atlantic Menhaden are not fully understood. Our objective was to quantify the effect of temperature on spatial and temporal variability in growth of age‐0 Atlantic Menhaden in Chesapeake Bay. We analyzed data on mean length and temperature for years 1962–2011 from nine regions of Chesapeake Bay. We developed a linear model that relates mean total length of Atlantic Menhaden to cumulative growing degree‐days (GDDs) in Chesapeake Bay and validated the model using data that were withheld from the initial parameter estimation. The temperature threshold that best described variability in growth was 14°C, a temperature substantially higher than the physiological threshold for growth. The GDD model explained almost 80% of the variability in mean length over time (within and among years) and among regions. In a model validation exercise, it accurately predicted mean length in tributary subregions of the bay not included in the original model fitting. The GDD model requires only temperature data to effectively predict growth, making it simpler to apply than models requiring more complex approaches. Received August 22, 2013; accepted May 30, 2014

“…However, the effects of climate change on recreational fishing are only starting to be considered (e.g. Kerr et al, reviewed the effects on recreational fisheries in the US Atlantic), despite the Intergovernmental Panel on Climate Change (IPCC) recognizing as early as 1997 that climate change could impact this activity (IPCC, ).…”

Marine recreational fishing and the implications of climate change

et al. 2019

Marine recreational fishing is popular globally and benefits coastal economies and people's well‐being. For some species, it represents a large component of fish landings. Climate change is anticipated to affect recreational fishing in many ways, creating opportunities and challenges. Rising temperatures or changes in storms and waves are expected to impact the availability of fish to recreational fishers, through changes in recruitment, growth and survival. Shifts in distribution are also expected, affecting the location that target species can be caught. Climate change also threatens the safety of fishing. Opportunities may be reduced owing to rougher conditions, and costs may be incurred if gear is lost or damaged in bad weather. However, not all effects are expected to be negative. Where weather conditions change favourably, participation rates could increase, and desirable species may become available in new areas. Drawing on examples from the UK and Australia, we synthesize existing knowledge to develop a conceptual model of climate‐driven factors that could impact marine recreational fisheries, in terms of operations, participation and motivation. We uncover the complex pathways of drivers that underpin the recreational sector. Climate changes may have global implications on the behaviour of recreational fishers and on catches and local economies.

“…Experimental and field-observational research in North American and European ecosystems has documented reductions in fecundity and egg quality when adult females do not experience a prolonged period of cold temperatures during the winter before spawning 11 12 13 14 . Because the number of viable eggs produced annually sets the absolute maximum potential cohort size for that year 15 , those aspects of climate change that affect fecundity and egg quality may strongly impact population dynamics and viability 16 17 . Climate change, therefore, may adversely affect reproductive success of temperate fishes by creating seasonal thermal regimes that are sub-optimal for reproductive development and by decoupling evolutionarily predictable relationships between temperature and photoperiod during seasonal transitions 6 , which largely govern the timing of reproduction.…”

“…A fuller understanding of how continued climate change, including the increase in frequency of short, warm winters in temperate regions 1 2 , will influence fish recruitment and population dynamics via reproductive pathways is essential to fisheries management and conservation efforts 16 . This need is especially evident given the focal species and experimental design used by previous studies that have investigated linkages between climate warming and fish reproductive success 11 .…”

Short winters threaten temperate fish populations

et al. 2015

Although climate warming is expected to benefit temperate ectotherms by lengthening the summer growing season, declines in reproductive success following short, warm winters may counter such positive effects. Here we present long-term (1973–2010) field patterns for Lake Erie yellow perch, Perca flavescens, which show that failed annual recruitment events followed short, warm winters. Subsequent laboratory experimentation and field investigations revealed how reduced reproductive success following short, warm winters underlie these observed field patterns. Following short winters, females spawn at warmer temperatures and produce smaller eggs that both hatch at lower rates and produce smaller larvae than females exposed to long winters. Our research suggests that continued climate warming can lead to unanticipated, negative effects on temperate fish populations.
