Tracking the impact of bottom trawling on benthic habitat status

open access: yesConservation 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.

Mapping the habitat of demersal fish resources to determine suitable fishing gear [PDF]

open access: yesBIO Web of Conferences
Proper use of fishing gear is important in fishing operations. This study aimed to determine a suitable type of fishing gear to be implemented in seven coastal districts in Bengkulu Province based on the results of mapping and analysis of demersal fish ...

Season- and depth-dependent variability of a demersal fish assemblage in a large fjord estuary (Puget Sound, Washington) [PDF]

open access: yes, 2011
Fjord estuaries are common along the northeast Pacific coastline, but little information is available on fish assemblage structure and its spatiotemporal variability. Here, we examined changes in diversity metrics, species biomasses, and biomass spectra (

Distribution of skates and sharks in the North Sea: 112 years of change [PDF]

open access: yes, 2016
How have North Sea skate and shark assemblages changed since the early 20th century when bottom trawling became widespread, whilst their environment became increasingly impacted by fishing, climate change, habitat degradation and other anthropogenic ...

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

open access: yesEconomic 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

Assessing Risk for Bycatch and Byproduct Species Using a Modified Sustainability Assessment for Fishing Effects (SAFE) Approach

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Central to ecosystem‐based fisheries management is ensuring the sustainability of bycatch and byproduct species. However, the sustainability of these species is difficult to assess as the lack of information limits the use of traditional stock assessment methods.
