Tracking the impact of bottom trawling on benthic habitat status

Conservation Biology, EarlyView.
Abstract Bottom trawling is the most widespread physical disturbance to marine benthic habitats, yet broadscale assessments of its impact remain limited. We developed a quantitative framework to evaluate trawling effects on benthic habitats at broad spatial scales based on the sentinels of seabed (SoS) indicator.

Does nature shape risk preferences? Evidence from Chile, Norway, and Tanzania

Economic Inquiry, Volume 63, Issue 2, Page 568-590, April 2025.
Abstract Does exposure to a more risky environment affect risk preferences? Going beyond single‐case study evidence, we report results from five surveys conducted in three countries and link this with administrative data to study whether a link between exposure and preferences is detectable and widespread. We find no evidence for endogenous preferences

Current state of stocks for demersal fish on the continental shelf in the exclusive economic zone of Russia in the northwestern Bering Sea

Известия ТИНРО, 2016
Stocks of demersal fishes on the depths of 20-200 m in the northwestern Bering Sea are considered, excluding walleye pollock Theragra chalcogramma , on the data of 10 bottom trawl surveys conducted in the summer-fall of 1985-2015.

Recreational Fisheries in Türkiye: Socio‐Economic Profiles, Technological Trends and Governance Challenges

Fisheries Management and Ecology, EarlyView.
ABSTRACT Recreational fisheries in Türkiye constitute an understudied socio‐economic sector spanning marine and freshwater ecosystems across the Mediterranean and Black Sea basins, yet robust national participation estimates remain constrained by the absence of a comprehensive registry or probability‐based sampling frame.

Bentho-pelagic relations in the deep-water part of the Okhotsk Sea by the data of stable isotopes С and N analysis

Известия ТИНРО, 2015
Composition, abundance, diet and trophic status are analyzed for dominant benthic and pelagic species in the deep-water Okhotsk Sea on the data collected in demersal and pelagic trawl surveys conducted by Pacific Fisheries Research Center (TINRO ...

Impact of fishing on size composition and diversity of demersal fish communities [PDF]

ICES Journal of Marine Science, 2000
By analysing data sets from different world regions we add evidence to documented changes in demersal fish community structure that may be related to fishing. Changes are analysed by community properties that might be expected to capture relevant overall changes – size spectra slopes and intercepts, Shannon-Wiener diversity, and dominance.

Residency and Space Use of Endangered Smoothhound Sharks (Mustelus mustelus) in Relation to Marine Protection and Demersal Longline Fishing Along South Africa's South Coast

Fisheries Management and Ecology, EarlyView.
ABSTRACT Shark populations are declining globally and the effectiveness of marine protected areas (MPAs) as a conservation tool may vary by species and environmental context. This study assessed space use and residency of smoothhound sharks (Mustelus mustelus)—an endangered, yet highly exploited shark—in relation to spatial protection and fishing risk ...

Spatio-temporal trends in diversity of demersal fish assemblages in the Mediterranean

Scientia Marina, 2019
The high species richness, coupled with high proportion of endemism, makes the Mediterranean one of the world’s ‘biodiversity hotspots’. However, the continuous increase in fisheries in the last few decades has led to the overexploitation of their main ...

Climate Vulnerability of Australian Seafood Systems: A National Assessment of Exposure and Adaptive Capacity

Fisheries Oceanography, EarlyView.
ABSTRACT Marine waters are becoming warmer and acidified and experiencing more intense and longer heatwaves under climate change. These changes are already impacting marine ecosystems and seafood production, which are vital for supporting food security and economic productivity.

Biophysical Factors Controlling Spatiotemporal Variability in Fishes' Early Life History Distribution in the Kattegat Ecosystem

Fisheries Oceanography, EarlyView.
ABSTRACT The Kattegat Sea acts as a nursery area for several fishes, exhibiting complex ichthyoplankton dynamics influenced by environmental factors and species‐specific traits. We investigated factors influencing spatiotemporal variability in yolk‐sac larvae presence and areal density for three economically and ecologically important fishes: sandeel ...
