Seabass recapture data in Tokyo Bay by Japan Game Fish Association (edited and filtered version)

This dataset provides individual-level tag and recapture records of
Japanese seabass (Lateolabrax japonicus) collected through an angler-based
tagging program conducted by the Japan Game Fish Association from 1987 to
2023 in Tokyo Bay, Japan. A total of 664 recapture cases are included
after data filtering, as described in the associated publication. Each
record contains information on tag ID, dates, and fork lengths at release
and recapture, and geographic locations coded by a custom mesh grid system
designed for spatial analysis within Tokyo Bay. Approximately 98% seabass
released in Tokyo Bay remained within the bay or its inflowing rivers.
These data were used to estimate growth rates across decades using the
GROTAG model and generalized additive models, which revealed size-specific
temporal shifts in growth patterns. The dataset is suitable for reuse in
studies related to seabass growth and migration ecology.
