Fish

As freshwater streams and native fish are threatened by changing environmental conditions, efforts to coalesce existing data and integrate modeling and projection tools are increasingly necessary for informing effective land, water, and species management. For example, identifying and integrating disparate datasets of streamflow, stream water temperature and species distribution is critical for de

The northeastern U.S. is home to a wide range of terrestrial and aquatic habitats, leading to a variety of interactions occurring between species and climate on multiple scales. Therefore, the most effective strategy to produce and deliver scientific climate information to resource managers is to align the scales of climate projections with the scales of resource management actions. While availabl

Inland recreational fishing, defined as primarily leisure-driven fishing in freshwaters, is a popular past-time which can provide substantial contributions to human consumption which are often overlooked at global scales. Here, we aim to establish a baseline of national inland recreational consumption estimates with species specificity to identify the nutritional composition and total use value of

The Republic of Palau, a Freely Associated State of the U.S. and a global leader in ocean conservation, recently implemented the Palau National Marine Sanctuary, which closed 80% of its ocean to fishing. As offshore fish become scarcer in the domestic market, managers have begun to worry about increased harvesting pressure on already overfished nearshore environments. This pressure, in addition t

Freshwater ecosystems support the health and well-being of human life and society through a myriad of services. Intact freshwater biodiversity maintains the health of freshwater ecosystems and the benefits they provide. However, staggering rates of freshwater biodiversity loss and declining ecological function of freshwater ecosystems threaten these natural benefits and human life. This project s

Nearshore marine ecosystems in Alaska and Hawai‘i rely heavily on organic materials and nutrients delivered by rivers and streams. It is hypothesized that the magnitude and timing of stream flows influences this delivery of materials to coastal ecosystems. However, despite previous research on the topic, there is still considerable uncertainty about how stream flow may influence these land-to-wate

Freshwater is a critical driver for island ecosystems. Climate change has fundamentally altered the water cycle in tropical islands. The changes in dynamic patterns of streamflow could result in the temporal and spatial difference in the riverine, estuarine, and coastal habitats that support native species. In particular, these habitats support the nine native aquatic species in Hawaiʻi at differe

Stream fish are in peril from a changing climate, particularly for species with restricted distributions or populations on the southern edge of their range. For these fish, the opportunity to escape warming temperatures is limited by the network of stream channels accessible to them. To deal with temperatures beyond their physical capacity, fishes must move, adapt, or die. However, little is known

Recreational angling in the U.S. represents a large group of people that catch and harvest fish for a variety of reasons, including for relaxation, adventure, social motivations, and consumption. Collectively, recreational anglers can exert pressures on both economies and fishery resources. Fish removals by anglers represent an important source of mortality data when trying to understand fish pop

Fisheries managers in Midwestern lakes and reservoirs are tasked with balancing multiple management objectives to help maintain healthy fish populations across a landscape of diverse lakes. As part of this, managers monitor fish growth and survival. Growth rates in particular are indicators of population health, and directly influence the effectiveness of regulations designed to protect spawning f

Aquatic invasive species threaten our lakes, streams, and wetlands. These species not only change the biology within the waterbody, but they can change the way we use those waterbodies and the resources they produce. Those changes may have large economic impacts, such as direct management costs and indirect costs to fisheries, tourism and commerce. These species can be small like zebra mussels or

Stocking, or raising fish in hatcheries and releasing them into a body of water, is routinely used to supplement or maintain fisheries when natural populations are low or nonexistent. Demand for stocking cool and coldwater fish species that support important fisheries will likely increase as a result of climate change, but fish available for stocking are a limited resource. Consequently, climate c
