Japan Tokyo Bay sea perch - purse seine

Primary tabs

Overview

Tokyo Bay is one of the leading commercial and recreational fishing regions in Japan for Japanese sea perch (Lateolabrax japonicus), a historically and culturally important fish used for edomae sushi, the style of sushi created during the late Edo-period (late 19th century) that influenced the nigiri sushi that is common today.

While archaeological sites show that species such as sea perch were consumed in the Tokyo Bay region as far back as 300 BC, commercial sea perch fishing in Tokyo Bay expanded during the Edo Period (1600-1850s) with new technology, gear, and techniques to match growing demand. The present-day mid-scale purse seine commercial sea perch fishery is permitted by the Chiba Prefecture government, and the majority of the sea perch purse seine vessels fishing in Tokyo Bay are managed by the Funabashi Fisheries Cooperative. While fishing is permitted year-round, peak season is during the summer.

Purse seine vessels which are participants of the Tokyo Bay Sea Perch FIP are significant players in the region’s industry and account for 10-15% of the total Chiba Prefecture sea perch catch. These fishermen, led by FIP client company Kaiko Bussan, abide by voluntary conservation practices including setting non-fishing days during spawning season and limiting soak times. While the local fishery research agency in Chiba prefecture conducts stock evaluations, prefecture-wide science-based fishery management plans and objectives are lacking, which increases the risk of overfishing and stock depletion. Specific deficiencies include the lack of harvest control rules used to reduce harvest when stock abundance is declining and the lack of fishery reference points based on maximum sustainable yield (MSY) or another appropriate proxy. In addition, the formal decision-making process is not very transparent and inclusive of stakeholders.

The Tokyo Bay Sea Perch FIP will increase the scientific understanding of the fishery, its effects and sea perch stocks, improve fish management practices, work to maintain overall sea perch stock abundance in Tokyo Bay, and distinguish the sea perch fishery in the growing sustainable seafood marketplace..

Update 
Update December 2021: Stakeholders of Japan Tokyo Bay Sea Perch Purse Seine FIP have decided to extend the target end date of their FIP to December 2023. The main reason for this extension is due to developments in the newly devised national fisheries resource management system (referred to as "New Resource Management Roadmap") as part of the revised national Fisheries Act that began implementation in 2020 and the implication that will have on resource management of Tokyo Bay sea perch. Resource management and stock assessment had been conducted at the prefectural level for sea perch before the amendment of Fisheries Act. Sea perch has been included as a target species that will require update in how resource management/stock assessment will be conducted. By extending the projected end date, the FIP stakeholders are planning to work with the Fisheries Cooperative Association, prefectural government and relevant research institutes to provide insight on the how sea perch should be managed based on word done through the FIP.

(C) Some Recent Progress
  • A FIP that has achieved a Stage 4 or 5 result in more than 12 (but less than 24) months AND has reported a Stage 3 activity within the past six months.
  • A FIP younger than 12 months that has never achieved a Stage 4 or 5 result but has reported a Stage 3 activity within the first 12 months.
(D) Some Past Progress
  • A FIP that has achieved a Stage 4 or 5 result in more than 12 (but less than 24) months BUT has not reported a Stage 3 activity within the past six months.
  • A FIP for which the most recent Stage 4 or 5 result is more than 24 (but less than 36) months old AND a Stage 3 activity has been reported within six months.
  • A FIP 12-36 months old that has never reported a Stage 4 or 5 result AND has reported a Stage 3 activity within the past six months.
