ProjectBroodstock and hatchery management. Support for technical services, LAO PDR 1999
Also available in:
No results found.This consultancy was carried out within the scope of the “Provincial Aquaculture Development Project” LAO/97/007 to assess the current problems and constraints regarding the situation of broodstock in both private and state hatcheries and propose recommendations for future action (Terms of Reference are in Annex 1 and itinerary & timetable in Annex 2). The consultancy included three 2-day training courses conducted in 3 regions for private and state hatchery managers. The training cour ses covered aspects of broodstock and hatchery management appropriate to Lao PDR fish seed stations and small–scale hatcheries. The consultancy also included the writing of a simple manual on broodstock management to be used later by fish seed farm staff and extension officers. This report is the result of the mission made by the consultant from 5/01/99 to 6/02/99, the manual being prepared separately. -
ProjectGuidelines for Broodstock and Hatchery Management 1999

No results found.The demand for fish fry in Lao PDR is currently estimated at 60 million per year and is constantly increasing. Most fish fry produced in the country originate from the Provincial government hatcheries, which have an estimated annual production of less than 11 million. This shortfall in supply is met in some part by the production activities of private farmers and more importantly through imported fish fry from Vietnam, Thailand and China. Imported fish fry is usually of poor quality an d has suffered extreme transport stress by the time it is stocked into the farmer’s ponds. The lack of choice of species and occasional cheating by middlemen also makes the purchase of this foreign fish fry less desirable. There is a high premium for fish fry produced in LAO PDR due mainly to farmer’s awareness that foreign imported fry is of poor quality. There are few private hatcheries providing fish fry to the provinces and thus the dependence upon production from the Provincial fi sh hatcheries remains. The low production from these hatcheries is due to a wide range of factors, but significant increase in production could be achieved merely by improvement of basic management techniques. As part of an initiative to improve the production from Provincial fish hatcheries, LAO/97/007 is providing assistance in the form of structural improvements and management training. Little attention has been paid to the issues of broodstock management in the past, since this has not been considered as being a critical issue. The result has been that the fish used for breeding in the hatcheries are usually not in an appropriate condition for production of good quality fry. The principle reasons for this are: poor nutrition, under sized animals, inadequate spawning techniques and possibly inbreeding problems. This manual is intended as a guide to hatchery managers and those involved in fish culture activities in Lao PDR. The emphasis of this manual is placed on appropriate techniques that are sensitive to the economic and management realities of Lao PDR. The final chapters of the manual are intended as a guide the effective planning of fish breeding and fry production in hatcheries, together with some examples of how to assess basic economic parameters essential for the sustainable operation of a small fish hatchery. -

Lao PDR is a land locked country located within Southeast Asia and has a wide range of climatic environments. The country is composed of mountainous upland regions and lowland plains with a total area of approximately 236,800 km2. Upland areas constitute approximately 75% of the total area of the country, with the lowlands occupying approximately 60,000 km2. The country has 57 major rivers mainly running from the north to the south of the country. The lowland areas of Lao PDR are suitable for aq uaculture, although aquaculture is practised in some of the upland areas.
