Abstract
Biotechnological studies have been conducted in 46 Prefectural Experimental Stations in Japan in 1991. In 41 of these, research focused on chromosome set manipulation including triploidy for sterilization and gynogenesis for sex control. Practical application of biotechnology for culture of each species is the main interest because each prefecture has its own project for promoting the local fisheries industry. Therefore, the commodities being studied are of commercial importance comprising of about 40 species.The culture production of Japan in 1988 totaled 1,426,000 tons, 95% of which consisted of 10 species. Biotechnology is not widely used since most seeds are not from hatcheries, but from the wild. Recently, however, promising results on the study of sex determination mechanism in the Japanese flounder have been adopted for actual seed production. This has attracted attention as an approach to mass production of all-female seedlings.

Mangrove-Friendly Aquaculture : Proceedings of the Workshop on Mangrove-Friendly Aquaculture organized by the SEAFDEC Aquaculture Department, January 11-15, 1999, Iloilo City, Philippines
Primavera, Jurgenne H.; Garcia, Luis Ma. B.; Castaños, Milagros T.; Surtida, Marilyn B. (Aquaculture Department, Southeast Asian Fisheries Development Center, 2000)The proceedings have three review papers on the mangroves of Southeast Asia, silvofisheries, and Indonesia's integrated mangrove forest and aquaculture systems. The rest of the papers, all on mangrove-friendly aquaculture efforts are from the Philippines, Japan, Thailand, Vietnam, Malaysia, Brunei Darussalam, Indonesia, and Cambodia. All the countries represented had varied methodologies, with Cambodia in its initial stages while some countries like Indonesia and Thailand have tested methodologies. The proceedings include a tabulation of the reported mangrove-friendly technology by country -- e.g. silvofisheries in ponds (mangrove and fish/shrimp/mudcrab) and pens (mangrove and mudcrab). The workshop recommendations are classified into three major topics: problems associated with mangroves, problems associated with aquaculture practices, and socioeconomic and cultural issues. -
Mass larval rearing technology of marine finfish in Japan
Fukusho, Kunihiko (Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)With economic development and increased demand for high price fish, industrial scale marine finfish culture in Japan was started in 1960-1965 for yellowtail Seriola quinqueradiata. Sustainable supply of wild juvenile and development of floating cage with synthetic fiber net have spurred the culture of nearly 30 species and total production in 1991 is 265 x 103 metric tons (nearly 25% of total aquaculture production). Although salmon ranching had been started in 1888, a national project of ocean ranching was only initiated in 1963 with the present target of 26 species of marine finfish. Ocean ranching aims to increase fisheries resources in coastal sea by stocking hatchery-reared juveniles and preservation of environmental capacity and habitat. Therefore, mass production of marine finfish juveniles is being done for the intensive culture in net cage and for stocking coastal sea in Japan. Nearly 200 million juveniles are produced by ocean ranching centers (14 national, 49 prefectural, 21 city and town, 53 fishermen's association). The number of target fish is about 60 species (excluding salmon and trout). The main species produced are red sea bream, Pagrus major, flounder, Paralichthys olivaceus, puffer, Takifugu rubrapes, rockfish, Sebastes shlegeli, and mud dab, Limanda yokohamae. More than one million juveniles of these species are produced at one hatchery or ocean ranching center per one fry production season. About 70% of total production of juveniles consist of red sea bream and flounder. Red sea bream could be used to introduce mass larval rearing technology in Japan since its mass production is well developed. The focus of the present paper is the present status and short history of the development in larval rearing technology for red sea bream. -
Towards sustainable aquaculture in Southeast Asia and Japan : proceedings of the Seminar-Workshop on Aquaculture Development in Southeast Asia, Iloilo City, Philippines, 26-28 July 1994
Bagarinao, Teodora, U.; Flores, Efren Ed C. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1995)Documents the presentations at ADSEA '94, the 3rd Seminar-Workshop on Aquaculture Development in Southeast Asia. ADSEA '94 includes reviews of the status of aquaculture development in Southeast Asia and Japan and of the researches conducted by Southeast Asian Fisheries Development Center, Aquaculture Department (SEAFDEC/AQD) to contribute to this development. Topics on responsible aquaculture, mollusc and seaweed culture, integrated farming, shrimp culture, diseases, and health management, and transgenic fish were also discussed. It also lists the research areas of 20 or so commodities prioritized for research at AQD for 1995-1997.
