Progress on Implementing Ecosystem-Based Fisheries Management in the United States Through the Use of Ecosystem Models and Analysis

Frontiers in Marine Science, 2019
Worldwide fisheries management has been undergoing a paradigm shift from a single-species approach to ecosystem approaches. In the United States, NOAA has adopted a policy statement and Road Map to guide the development and implementation of ecosystem ...

Drivers of the North Aegean Sea Ecosystem (Eastern Mediterranean) Through Time: Insights From Multidecadal Retrospective Analysis and Future Simulations

Frontiers in Marine Science, 2022
Ecosystem models are important tools for the implementation of Ecosystem Based Fisheries Management (EBFM), especially in highly exploited ecosystems affected by climate change, such as the Mediterranean Sea.

Barriers to implementation of dynamic reference points in fisheries management

FACETS, 2023
Fish populations are dynamic; their productivity depends on the environment, predator and prey interactions, and fisheries harvest rates. Failure to account for these factors in fisheries science and management can lead to a misestimation of stock ...

Trends in the abundance of Celtic Sea demersal fish: Identifying the relative importance of fishing and environmental drivers

Frontiers in Marine Science, 2022
The Celtic Sea is a productive fishing ground, therefore identifying the relative importance of fishing and environmental factors on fish stock dynamics is crucial for developing our understanding of sustainable yields and to operationalize Ecosystem ...

Exploring the relationship between static fishing gear, fishing effort, and benthic biodiversity: a systematic review protocol

Environmental Evidence, 2021
Background and objectives The environmental effects of static gear fishing include habitat-level effects such as permanent changes to the physical environment and the structure of the benthic and epibenthic communities.

Economic and Ecosystem Effects of Fishing on the Northeast US Shelf

Frontiers in Marine Science, 2019
Modeling tools that can demonstrate possible consequences of strategies designed to operationalize ecosystem-based fisheries management (EBFM) should be able to address tradeoffs over a wide suite of considerations representing the scope of marine ...

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

An Optimal Control Framework for Multi‐Species Harvesting in the Southern Black Sea

Natural Resource Modeling, Volume 39, Issue 4, November 2026.
ABSTRACT The management of marine fisheries requires balancing ecological sustainability with economic profitability, particularly in ecosystems vulnerable to overexploitation. This study develops a multi‐species optimal control modeling framework for the southern Black Sea, focusing on three key species: horse mackerel (Trachurus mediterraneus) as ...

Food web structure, the hub index and identifying species of ecological significance

Ecological Indicators
Ecosystem based fisheries management (EBFM) attempts to take a broader perspective to the management of natural resources. To date it has often focused on the status of specific stocks, species or habitats.
