Job describtion:	The main task of this assignment was to compile a final report of the project. In addition, a feasibility study was made for the introduction of the white shrimp (Lithopenaeus vannamei) for experimental purposes to the wetlabs of the group. This included the identification of suitable seed producing institutions, planning of the logistics, and preparation of a management set up for the culture of this species in closed recirculation systems.

Year / country:	1999 - 2000, The Netherlands.

Job describtion:	Applied research. A dose-response experiment with European eel (Anguilla anguilla) was designed and executed. In collaboration with TNO-ILOB five extruded diets were produced for the trial, and the physical quality of the pellets determined. Samples of both fish and diets were subjected to proximate and fatty acid analysis. In addition, a similar study was carried out to determine the suitability of the expander pelleting technique for the production of fish feeds.

Year / country:	1996 - 1998, Tanzania.
Company:	UN FAO - Aquatic Resource Management Programme for Local Communities. - Improvement of aquaculture and fisheries management practices for rural communities.
Job describtion:	Aquaculture research and extension. To increase the production of semi-intensive aquaculture an on farm trial with alternative sources feed and fertilisation was carried out. The result of this investigation have been used to develop and improve an aquaculture extension package, which was tested under local conditions. Fisheries management. For a variety of small water bodies fisheries management strategies were developed, improved and introduced. To do so, an extension programme and package for improved fisheries management was formulated. Local staff of the Fisheries Division was trained in improved fisheries management and fisheries catch statistics. Introduced techniques and new methods were monitored, analysed and evaluated. Database management. An inventory of small water bodies in Tanzania was made. Physico-chemical, fisheries and socio-economic data of small and medium sized water bodies were collected from maps, literature and a number of institutes and integrated in a regional database.

Fishaid Project

Year / country:

1994 - 1996, Papua New Guinea.

Organisation:

UN FAO Fishaid Project - Enhancement of fisheries production through introduction of new fish species.

Job describtion:

Aquaculture engineering. A multi-purpose closed recirculation system was designed and constructed with local available tools and equipment. After completion the facility was used to quarantine imported fish eggs and fish fry which were raised up to fingerling stage.
Fish health and logistics. Suitable fish seed producing institutes were identified and a co-operation programme with the partner institutes established. Aquaculture staff were educated in fish health and quarantine procedures. For a large number of international fish transports the logistics were organised and co-ordinated.
Aquaculture. Responsibilities included the supervision of 3 staff members and the daily management of the fish culture station and the water treatment facilities. A variety of fish species (Red breasted tilapia (Tilapia rendalli), Silver barb (Puntius gonionotus), Pacu Collosoma bidens, Prochilodes sp. Golden masheer (Tor putitora), Snow trout (Schizothorax richarsoni)) were cultured from egg stage to adulthood. Periodically the quarantined fish were tested for diseases and treated when necessary. Fish feeds were formulated and produced using locally available inputs.
Field work. Suitable stocking sites for the fish were selected throughout the project area on the basis of ecological and socio-economic information, and logistics for the introduction of the new fish species arranged. The effect of the fish introductions on the fisheries production and the economy of the rural population were monitored.
Extension activities. Awareness activities to promote fish as a commodity and training for the local communities on the management and exploitation of the fisheries resources, were organised.
Training of staff. Counterparts and technicians were trained in the management of the quarantine facility, diagnosis and treatment of common fish diseases, techniques for limnological research and fisheries statistics, and awareness training for local communities on management and exploitation of the fisheries resources.
