Use of remotely-derived bathymetry for modelling biomass in marine environments [PDF]

, 2013
The paper presents results on the influence of geometric attributes of satellite-derived raster bathymetric data, namely the General Bathymetric Charts of the Oceans, on spatial statistical modelling of marine biomass. In the initial experiment, both the

Monitoring small‐scale fisheries through participatory, app‐based surveys in the tropical archipelago of São Tomé and Príncipe

Conservation Science and Practice, EarlyView.
Small Island Developing States have limited capacity to monitor Small Scale Fisheries, despite their high dependence on marine resources. Participatory monitoring of Small Scale Fisheries can fill data gaps while integrating resource users into fisheries management.

Can higher resource utilization be achieved in demersal fish supply chains? Status and challenges from Iceland and Norway

Resources, Environment and Sustainability
Most of the harvested demersal fish from Norway and Iceland is from sustainable, but fully exploited fish stocks. Increasing the harvest is therefore not considered a feasible option to meet the future global demand of seafood.

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

Using hydrodynamics to modify fishing performance of a demersal fishing gear

Fisheries Research, 2023
This study demonstrates how hydrodynamics can be used to influence the fishing performance of towed demersal fishing gears. Sea trials are performed in the sea star fishery to show how modifications to the gear design alter the hydrodynamics of the turbulent wake and consequently affect the catching performance of trawl gears.

Classification of European Illex coindetii and Loligo forbesii Squid Stocks by Trace Element Analysis of Statoliths

Fisheries Management and Ecology, EarlyView.
ABSTRACT We investigated whether statolith microchemistry analysis could classify ommastrephid and loliginid squid species into fishery stocks. Statolith nucleus (early life stage) and edge (life stage at time before catch) of Illex coindetii (Verany, 1839) and Loligo forbesii (Steenstrup, 1856) from various areas of the North East Atlantic Ocean and ...

A dual pathways transfer model to account for changes in the radioactive caesium level in demersal and pelagic fish after the Fukushima Daï-ichi nuclear power plant accident. [PDF]

PLoS ONE, 2017
The Fukushima Daï-ichi nuclear power plant (FDNPP) accident resulted in radioactive Cs being discharged into the local marine environment. While Cs bioaccumulates in biota and slowly depurates, the Cs concentrated in biota constitutes a source of Cs for ...

Ecosystem Impacts of the Landing Obligation for Unwanted Catch in Thermaikos Gulf (Greece)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Discards by marine commercial fisheries have been an issue of major concern to the scientific community in recent years. We modeled the ecological and trophic consequences of a mandatory landing obligation (LO) regulated by the reformed Common Fisheries Policy [Regulation (EU) 1380/2013] on the Thermaikos Gulf ecosystem (northwestern Aegean ...

CONSTRUCTION ANALYSIS OF BOTTOM GILLNET AS AN ALTERNATIVE TO BOTTOM TRAWL IN PEKALONGAN WATERS [PDF]

Russian Journal of Agricultural and Socio-Economic Sciences, 2019
A bottom trawl is a fishing tool that is not recommended by the government to capture demersal fish resources in Pekalongan waters. Therefore, a bottom gillnet is an alternative substitute for bottom trawl fishing gear in catching demersal fish.
