Training Course in Coldwater Fisheries

No results found.The Islamic Republic of Iran has an established coldwater fish culture industry in both the private and public sectors, centred in the northern mountains close to the Caspian Sea and in other high areas of the country. Rainbow trout (Salmo gairderi) are grown to a market size of 250 g and above in conventional farms, predominantly using concrete raceways. Official 1987 production was 1 750 t from 20 licensed farms, but it is thought that unlicensed farms contribute about a further 1 000 t to the true total. The “Caspian salmon”, actually an anadromous trout (Salmo trutta), is grown in hatcheries to a size of 1–20 g before being released into the rivers and streams draining into the Caspian Sea. Demand for trout in Iran greatly exceeds domestic production. Consequently the Government is currently supporting a major programme to increase salmonid output, both by building state-owned hatcheries and on-growing units and by providing licences, land and juvenile fish to private farmers. Ex tension advice is also available through the Shilat (State fishery company). However, this rapid expansion of coldwater fish culture has resulted in a national shortage of trained people capable of managing trout farms or of providing an efficient extension service. In addition, there is a need for technical staff already actively working in the industry to update their knowledge. As no universities or colleges in Iran are presently equipped to offer specialized training in this field, the Gov ernment of the Islamic Republic of Iran requested FAO assistance in organizing and staffing a theoretical and practical training course in coldwater fish culture. Funding was agreed under FAO's Technical Cooperation Programme (project TCP/IRA/6755). -

Establishment of a Network of Aquaculture Centres in Asia
1985Also available in:
No results found.Lates calcarifer (Bloch), commonly called the giant sea perch or seabass, is an economically important food fish in the tropical and subtropical regions of Asia and the Pacific. It is commercially cultivated in Thailand, Malaysia, Singapore, Indonesia, Hong Kong and Taiwan, in both brackishwater and freshwater ponds, as well as in cages in coastal waters. Because of its relatively high market value, it has become an attractive commodity of both large to small-scale aquaculture enterprises. Howev er, the major constraint to rapid expansion of seabass culture has been the inconsistent supply of fry collected from the wild. It fluctuates widely from year to year, making forward planning for production difficult. In the early 1970's, Thai scientists have achieved success in the breeding of seabass under captive conditions. Completion of its life cycle has also been accomplished. Growth performance of the hatchery-bred fry has been shown to be comparable with that of fry collected from the wild. Thailand is presently producing more than 100 million fry annually (Anon. 1985), with the Satul Fisheries Station producing more than 30 million (Kungvankij 1984). Thus, the seabass culture industry in Thailand is now assured of sufficient and consistent supply of fry. In order to extend the technology of seabass culture, this manual is prepared to serve as a practical guide for extension workers and farmers. Its contents are based on research findings in addition to many years of accum ulated practical experience and field observations.
