Hydrobiologia, 2023
The common bottlenose dolphin (Tursiops truncatus) is a top marine predator widely dispersed in coastal and pelagic habitats and with a generalist feeding behavior.

Spatial approximation of jack mackerel eDNA concentration.

, 2016
Based on CytB gene copy number in a 2 μL template DNA solution at the 47 sampling station, spatial variation of jack mackerel eDNA in west Maizuru Bay was estimated by approximation.

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

Microplastic in the stomachs of open-ocean and deep-sea fishes of the North-East Atlantic.

Environmental Pollution, 2020
The presence of microplastic in marine fishes has been well documented but few studies have directly examined differences between fishes occupying contrasting environmental compartments.

From shell to shelter: investigating small reef fish abundance on degraded seafloor restored with mussels and shell material

Restoration Ecology, EarlyView.
Abstract Introduction Reef‐forming shellfish facilitate biodiversity through providing structural complexity in benthic habitats. Globally, reef‐forming shellfish have been overharvested to near extirpation, with a corresponding loss in biodiversity. Mussel shell material, an aquaculture by‐product, has the potential to rehabilitate ecosystem services ...

Causal Models as a Scientific Framework for Next‐Generation Ecosystem and Climate‐Linked Stock Assessments

Fish and Fisheries, Volume 27, Issue 4, Page 942-959, July 2026.
ABSTRACT Rapid changes in marine ecosystems highlight the need to account for time‐varying productivity in stock assessments used to support fisheries management. Common approaches incorporate annual variation or regressing processes such as recruitment, natural mortality, or growth on environmental variables.

Vertical Habitat Use by Japanese Jack Mackerel Trachurus japonicus Inferred From a Biologging Study in Tokyo Bay

Fisheries Oceanography, Volume 35, Issue 4, Page 518-531, July 2026.
ABSTRACT The movement ecology of Trachurus japonicus in the adult stage remains poorly understood because observing their underwater behavior over long periods is challenging. This study aimed to examine vertical habitat use by T. japonicus using electronic tags. Ninety fish were tagged and released in November 2022 in Tokyo Bay, Japan.

Environmental and Protection Effects of Shark‐Companion Associations Across Three Ocean Basins

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Companion species frequently associate with large marine hosts, yet the ecological drivers of these relationships remain poorly understood. Using a global dataset of midwater BRUVS deployments, we modelled the presence and abundance of shark‐companion associations across seven shark species and three ocean basins.
