Resource Assessment Report No. 2: West Coast Demersal Scalefish Resource 2025 Assessment, Emily A. Fisher, David V. Fairclough, Elaine Lek, Jeremy Briggs, Sybrand Alex Hesp, Ainslie Denham Sep 2025

Resource Assessment Report No. 2: West Coast Demersal Scalefish Resource 2025 Assessment, Emily A. Fisher, David V. Fairclough, Elaine Lek, Jeremy Briggs, Sybrand Alex Hesp, Ainslie Denham

Resource Assessment Reports

The West Coast Demersal Scalefish Resource (WCDSR) comprises over 100 species inhabiting inshore (20-250 m deep) and offshore ( > 250 m deep) waters of the West Coast Bioregion (WCB; north of Kalbarri to east of Augusta). The WCDSR is primarily targeted by commercial, charter and recreational boat-based line fishers, including the commercial West Coast Demersal Scalefish (Interim) Managed Fishery (WCDSIMF). Indicator species selected for monitoring and assessing the status of the inshore suite of the WCDSR include Snapper, WA Dhufish and Baldchin Groper, while indicators for the offshore suite include Hapuku, Bass Groper and Blue-eye Trevalla.

The WCDSR is more …


Resource Assessment Report No. 4: North Coast Demersal Scalefish Resource - Kimberley 2025 Assessment, Fabian Trinnie, Rubie Evans-Powell, Ainslie Denham, Sybrand A. Hesp, Corey Wakefield, Craig L. Skepper, Brett Crisafulli, Stephen J. Newman Sep 2025

Resource Assessment Report No. 4: North Coast Demersal Scalefish Resource - Kimberley 2025 Assessment, Fabian Trinnie, Rubie Evans-Powell, Ainslie Denham, Sybrand A. Hesp, Corey Wakefield, Craig L. Skepper, Brett Crisafulli, Stephen J. Newman

Resource Assessment Reports

The North Coast Demersal Scalefish Resource (NCDSR) comprises ecological suites of tropical demersal fish species that occur predominantly in inshore waters (20–250 m deep) and offshore waters ( > 250 m deep) of the North Coast Bioregion (NCB). More than 60 demersal species are landed by fisheries operating in the Kimberley and Pilbara regions of the NCB each year, including high-value snappers (Lutjanidae), groupers (Epinephelidae), and emperors (Lethrinidae). As outlined in the NCDSR Harvest Strategy (DPIRD, 2017), the Kimberley resource is currently monitored through annual reviews of total removals and catch rate trends of indicator species, as well as periodic (every …

Characterizing Fish Communities Using Traditional And Emerging Monitoring Approaches In San Diego County Estuaries, Natalie Katherine De Wet Aug 2025

Characterizing Fish Communities Using Traditional And Emerging Monitoring Approaches In San Diego County Estuaries, Natalie Katherine De Wet

Theses

Fish communities are essential to estuarine health, playing key roles in food webs, nutrient cycling, and ecosystem functioning. However, the persistence of native fish populations is increasingly threatened by the cumulative impacts of coastal development, pollution, and climate change. Rapid, effective monitoring of species distributions is a priority, enabling timely conservation and management. However, the study of any ecosystem is limited by time, resources, and the consideration that research of a system can damage the ecosystem under study.

This research aimed to characterize fish species richness and evaluate the benefits and limitations of different estuary monitoring approaches. Specifically, this study …

The Future Intensification Of Hydrological Extremes And Whiplashes In The Contiguous United States Increase Community Vulnerability, Surendra Maharjan, Wenzhao Li, John D. Bolten, Hesham El-Askary Aug 2025

The Future Intensification Of Hydrological Extremes And Whiplashes In The Contiguous United States Increase Community Vulnerability, Surendra Maharjan, Wenzhao Li, John D. Bolten, Hesham El-Askary

Mathematics, Physics, and Computer Science Faculty Articles and Research

Hydroclimatic whiplash rapid shifts between drought and flood poses growing risks to U.S. communities. Here, we assess historical extremes and future projections using a normalized streamflow metric: the annual mean flow’s deviation from the 1981–2020 average, expressed as a fraction of that average. This metric is applied to United States Geological Survey records and Localized Constructed Analogs downscaled projections under Representative Concentration Pathways 4.5 and 8.5. Results reveal sharp regional disparities, with drought deficits exceeding 300% of normal flow during multi-year droughts. By linking hydrologic outcomes with the Federal Emergency Management Agency’s National Risk Index, we find that counties facing …
