Fish Space Use and Behavior in an Aquarium: The Use of Microhabitats as Enrichment

open access: yesZoo Biology, EarlyView.
The inclusion of microhabitats in a stream tank serves as environmental enrichment for fish in human care. ABSTRACT Environmental enrichment is an important tool to maintain the health and well‐being of animals in human care, but studies of environmental enrichment for fish in human care have lagged behind those of land animals.

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
