Dietary inclusion effect of various levels of jack mackerel meal on the growth performance, feed efficiency and whole body composition of rockfish (Sebastes schlegeli)

Fisheries and Aquatic Sciences, 2021
Inclusion effect of various levels of jack mackerel meal (JMM) acting as feed attractants and/or stimulants in diets on the growth, feed consumption, feed utilization and whole body composition of rockfish was ...

Interannual Variations in Distribution and Density of Japanese Anchovy (Engraulis japonicus) Larvae in the Shelf‐Break Region of East China Sea During Spring (2001–2022)

Fisheries Oceanography, Volume 35, Issue 5, Page 777-794, September 2026.
ABSTRACT Japanese anchovy (Engraulis japonicus) is the most abundant fish in the East China Sea (ECS) and an important fishery resource throughout its life stages. Using samples collected along the ECS shelf‐break in April over a 22‐year period (2001–2022), we examined the horizontal distribution and interannual variability of larval density (mean ...

Otolith Shape Variation Reveals a Preliminary and Novel Stock Structure Signal of Yellowtail Kingfish (Seriola lalandi lalandi) in Aotearoa New Zealand

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Climate‐driven range expansion is reshaping marine species distributions and complicating stock assessment, including for Yellowtail Kingfish (Seriola lalandi lalandi) in Aotearoa New Zealand, which have recently expanded southward from a historically northern range.

Variability in Fish Environmental DNA Concentration in Coastal Ecosystems at Hierarchical Levels: Focusing on the Magnitude, Structure, and Environmental Dependence

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Differences in eDNA concentration heterogeneity under the TPL framework suggest a concentration‐dependent survey design to minimize noise in eDNA quantification. In addition, whilst spatial and temporal variations in eDNA concentration could be primarily determined by ecological factors such as the distribution and dynamics of individuals, variations ...

Advancing Ecological Understanding and Sustainable Management of Small Pelagic Fish

Fish and Fisheries, Volume 27, Issue 4, Page 850-864, July 2026.
ABSTRACT Small pelagic fish (SPF) are critical to the trophodynamic structure and function of marine systems and support some of the most valuable and socially important fisheries worldwide. Their “boom and bust” population dynamics, shifts in distribution, and importance as forage resources for other fish stocks place unique challenges to assessing ...

Using Stock Vulnerability to Evaluate Fishery‐Independent Survey Coverage and Inform Sampling Priorities

Fish and Fisheries, Volume 27, Issue 4, Page 912-926, July 2026.
ABSTRACT The consequences of mis‐managing vulnerable stocks (i.e., those with low productivity and high susceptibility to depletion) are high and potentially permanent. To support sustainable fisheries management, stock assessments can be improved by increasing the quantity and quality of fishery‐independent survey (i.e., survey) data.

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.

Thinking of Fish Population Discrimination: Population Average Phenotype vs. Population Phenotypes

Frontiers in Marine Science, 2021
The genetic polymorphism and phenotypic variation are key in ecology and evolution. The morphological variability of the contour of fish otoliths has been extensively used for the delimitation of stocks.

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.

Impacts of Strong ENSO Events on Fish Communities in an Overexploited Ecosystem in the South China Sea

Biology, 2023
To better understand how fish communities respond to environmental changes under extreme climate events, we examine changes in fish communities in Beibu Gulf during strong El Niño and La Niña events.
