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

open access: yesFisheries Oceanography, EarlyView.
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.

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

Surgical tagging of Atlantic mackerel (Scomber scombrus): electroanaesthesia and survival in captivity and the field

open access: yesJournal of Fish Biology, EarlyView.
Abstract Electroanaesthesia using electric fish handling gloves induced rapid and reversible sedation of Atlantic mackerel (Scomber scombrus) during surgical tagging without observable adverse effects on behaviour or tag retention. In the laboratory, survival analyses revealed that longer handling times and smaller body sizes significantly reduced ...
