Potential impacts of ocean warming on energy flow and fisheries production in an overexploited ecosystem: Implication for effective fisheries management

Ecological Indicators
The influences of ocean warming on marine lives have accelerated over the 21st century, greatly altering the structure and function of marine food webs and causing distributional shifts, species invasions, and changes in productivity. It is imperative to

Estimating the Impact of a Seasonal Fishing Moratorium on the East China Sea Ecosystem From 1997 to 2018

Frontiers in Marine Science, 2022
Fisheries management policies (FMPs) have been implemented in coastal countries to ensure a sustainable supply of seafood and the recovery of species diversity. Because of the depletion of fishery stocks, China has introduced a series of FMPs since 1995,

Using Ecopath with Ecosim to Explore Nekton Community Response to Freshwater Diversion into a Louisiana Estuary [PDF]

Marine and Coastal Fisheries, 2012
Abstract Current methods to restore Louisiana's estuaries include the reintroduction of Mississippi River water through freshwater diversions to wetlands that are hydrologically isolated from the main channel. The reduced salinities associated with freshwater input are likely affecting estuarine nekton, but these effects are poorly ...

Combined Effects of Environmental Drivers on Marine Trophic Groups – A Systematic Model Comparison

Frontiers in Marine Science, 2019
The responses of food webs to simultaneous changes in several environmental drivers are still poorly understood. As a contribution to filling this knowledge gap, we investigated the major pathways through which two interlinked environmental drivers ...

Identifying drivers of change during the recent two decades in the Visayan Sea using a trophic modeling approach

Frontiers in Marine Science, 2023
The Visayan Sea is one of the major traditional fishing grounds in the Philippines and is likewise considered as a top contributor to the country’s overall fisheries production.

Trophic modelling of marine ecosystems and ecosystem based fisheries management [PDF]

, 2017
Fish populations are an integral part of marine ecosystems. Historically, fish population dynamics have been studied as single species, for example as mackerel, shrimp or sardine, and almost always in isolation from the system in which they exist.

Bottom‐Up Interactions in State‐Space Age‐Structured Models Using Mass‐Balance Dynamics

Fish and Fisheries, Volume 26, Issue 6, Page 1048-1064, November 2025.
ABSTRACT Age‐structured models are used worldwide to regulate fisheries. These models typically ignore top‐down interactions (predation affecting natural mortality) and bottom‐up interactions (consumption affecting individual growth, reproduction, or survival), whereas multispecies catch‐at‐age models often incorporate top‐down but not bottom‐up ...

Increase in Harp Seal Ecosystem Role After the Cod Collapse in Newfoundland & Labrador

Fish and Fisheries, Volume 26, Issue 5, Page 878-894, September 2025.
ABSTRACT Pinniped populations have been increasing worldwide, posing challenges for fisheries management, including damage to fishing gear and competition for resources. In the Northwest Atlantic, harp seal numbers have increased from 1.8 million in 1970 to 6.5 million in 1990, stabilising at 4.4 million in 2024—one of the largest pinniped populations ...
