Small Differences in Diet Facilitate the Coexistence of Three Forage Fish Species in an Inshore Northern Patagonian Habitat

Frontiers in Marine Science, 2022
Forage fish play the crucial role of transferring energy from lower to upper trophic levels. These small pelagic fish feed on plankton and can compete with each other for food, leading to potentially complex interactions.

Ecosystem-based fisheries management increases catch and carbon sequestration through recovery of exploited stocks: The western Baltic Sea case study

Frontiers in Marine Science, 2022
Legal requirement in Europe asks for Ecosystem-Based Fisheries Management (EBFM) in European seas, including consideration of trophic interactions and minimization of negative impacts of fishing on food webs and ecosystem functioning. This study presents

Low-Income Fish Consumers’ Subsidies to the Fish Reduction Industry: The Case of Forage Fish

World
Forage fish, a crucial source of nutrition in developing countries, are, unfortunately, primarily used for fishmeal and aquafeed production for aquaculture, which mainly serves consumers in developed countries. Industrial fish use leaves a meager portion

The biodiversity crisis in Canada: failures and challenges of federal and sub-national strategic and legal frameworks

FACETS, 2021
Pacific sand lance (Ammodytes personatus) and surf smelt (Hypomesus pretiosus) are ecologically important forage fish in the marine food webs within the Salish Sea, including British Columbia (BC). Although important, little information exists around the

Identifying trade-offs and reference points in support of ecosystem approaches to managing Gulf of Mexico menhaden

Frontiers in Marine Science, 2023
Gulf menhaden (Brevoortia patronus) support the largest fishery by yield in the Gulf of Mexico (GoM) and are a key forage species for many marine predators.

Exploring social-ecological trade-offs in fisheries using a coupled food web and human behavior model

Ecology and Society, 2021
Marine fisheries represent a social-ecological system driven by both complex ecological processes and human interactions. Ecosystem-based fisheries management requires an understanding of both the biological and social components, and management failure ...

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution

Advanced Science, EarlyView.
Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...
