Stocking(releasing)AquacultureAims of establishment of the Farming Fisheries Center
We have enjoyed the bounty of nature from the sea since ancient times. In recent times, the growth ofjuvenile fish has been hampered by the decreased seaweed beds and tidelands, which makes it difficult tomaintain and increase the catches of aquatic animals without resorting to fish stocking (releasing).
In Hiroshima Prefecture, in order to recover rich and bountiful sea, the Farming Fisheries Center wasestablished in 1982 as the facility to ensure large supply of juvenile fish for stocking and make it a base forpromoting the farming fisheries that will lead the new period.
Japanese rockfish (Sebastes inermis)

Overview of the businessIn accordance with the Hiroshima Prefecture farming fishery basic plan and based on the seedling production
and releasing plans that are mainly coordinated and examined by fishery operators, the seedlings of the eightspecies of fish are produced: red sea bream, Japanese rockfish, marbled rockfish, devil stinger, Japanese blue
crab, greasy-back prawn, Pacific oysters, and sweetfish. (As for bastard halibut, consignment production iscarried out).
Regarding the intermediary of seeds and seedlings and coordination as to the cost burden, the Hiroshima
Prefecture Fisheries Promotion Foundation is responsible for the six species of fish including red sea bream,Japanese rockfish, marbled rockfish, devil stinger, Japanese blue crab, and greasy-back prawn; the Hiroshima
Prefecture Federations of Fisheries Cooperatives are in charge of Pacific oysters; and the Hiroshima Prefecture
Federation of Inland Water Fisheries Cooperatives is in charge of sweetfish.
The production of seeds and seedlings of Japanese rockfish is carried out on consignment from theToyotakehigashi Fisheries Promotion Council.
The seeds and seedling production of redspotted grouper is carried out as part of the “Pilot production for massproduction” entrusted by the relevant organizations and funded by the Hiroshima Prefecture Fisheries Promotion
Foundation.
In addition, mass production of seeds and seedlings of Japanese blue crab (1 .5million pieces), marbled rockfish(300,000 pieces), devil stinger (150,000 pieces), and redspotted grouper (36,000 pieces) are implemented on
consignment from Hiroshima Prefecture. Moreover, the Center strives for the establishment and development of
the farming fisheries through recognition of the role of seedling production under Prefecture to cities collaboration,
examination of equivalent exchange of seedlings with the adjacent prefectures, technology exchange regarding
farming fisheries, information exchange, and guidance and education.

 Improvement of the survival rate after settlement of devil stinger
 Examination of production efficiency toward mass production of
triploid Japanese oyster Technology development/establishment toward seeds andseedling production of redspotted grouper
 Examination of feeding and rearing methods for the early egg
collection from the farmed broodstock (adult) devil stinger andestablishment of rearing techniques during the floating stage
