Status Pengelolaan Sumberdaya Ikan Demersal Sekitar Pantai di Kabupaten Indramayu, Jawa Barat

Omni-Akuatika, 2017
The status of fish resources in management fisheries context is important to be known for setting resources policy in order to ensure continuity of fish stock and harvest.

Analysis of Demersal Fish Schooling Distribution in Tarakan Waters North Borneo by Using Hidroacoustic Method [PDF]

, 2015
This research is aimed to determine the distribution of demersal fish schooling and the relation between demersal fish schooling and temperature, salinity and depth of water by using hydroacoustic method.

Ontogeny of foraging behaviour in an opportunistic gull inhabiting urban marine ecosystems

Wildlife Biology, EarlyView.
Urbanization affects ecosystems by reducing biodiversity and displacing species from native habitats. While some suffer, others, like urban wildlife, adapt through innovative feeding and behaviours that improve their fitness in human‐altered settings. Despite research on wildlife in urban areas, the development of foraging behaviour in urban species is

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.

Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony‐specific population trajectories at South Georgia

Conservation Biology, EarlyView.
Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

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.

Reconsidering the role of introduced species in the climate‐affected and highly invaded eastern Mediterranean

Conservation Biology, EarlyView.
Abstract Bioinvasions are considered mostly as a biodiversity and conservation hazard, but in specific situations, introduced species can bring ecological or socioeconomic benefits. We assessed the social–ecological role of marine introduced species in the eastern Mediterranean Sea—a global hotspot of bioinvasions and extirpations—and their potential ...

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 ...

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.
