The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Preliminary investigation of mitochondrial dna variation in jack mackerel (Trachurus declivis, carangidae) from south-eastern australian waters

open access: yes, 1994
A preliminary investigation of the genetic structure of jack mackerel (Trachurus declivis, Carangidae) in south-eastern Australian waters was conducted by using restriction enzyme analysis of mitochondrial DNA (mtDNA).

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

open access: yesFisheries 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)

open access: yesFisheries Oceanography, EarlyView.
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 ...

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

open access: yesJournal 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 ...

Status of the Jack Mackerel resource and its management [PDF]

open access: yes, 1973
The jack mackerel, Trachurus symmetricus, resource off the west coast of North America is known to be large and widely distributed. The spawning biomass is estimated to be 2.1 to 4.8 million tons based upon abundance of jack mackerel eggs collected at ...

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

open access: yesRestoration 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 ...

Advancing Ecological Understanding and Sustainable Management of Small Pelagic Fish

open access: yesFish 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 ...

Age, Growth and Reproductive Cycle of the Jack Mackerel Trachurus japonicus in the Southwestern Sea of Japan [PDF]

open access: yes, 2023
The growth and reproductive cycle of the jack mackerel (Trachurus japonicus) that were caught in the southwestern Sea of Japan during 2016-2017 were examined based on otolith annuli and gonad histology. Translucent and opaque zones on transverse sections
