Optimisation of shrimp feed, formulation and production in Seychelles. With this feed the production in an intensive farm increased from a maximum of 3 tons shrimp per pond (0.5 ha) to an average of 5 tons shrimp biomass per pond (average size: 35 g).

Formulation of a special high salinity diet for P. indicus which resulted in an improvement of farming results (Shrimp reaching 18-22 g in about 4 months, FCR: 1.1-1.4) Development of the production of shrimp feeds in Portugal in an existing extrusion plant for fish feeds: formulation of shrimp postlarval and growout feeds. This feed was exported to various countries in Europe and West Africa. Development of the production of shrimp feeds in Madagascar: adaptation of existing livestock feedmill to produce shrimp feeds: design of new machinery to add, start-up of production of shrimp feeds, research in the utilisation of more local ingredients, training of production managers, sales of those shrimp feeds, visiting customers (shrimp farmers). Production of feeds for biofloc culture of Litopenaeus vannamei in Belgium, used by 4 farms and 2 research institutes. Production of shrimp feeds for different customers in Iran (pelleting and extrusion) Assistance to improve production methods for shrimp feeds in New Caledonia Feed development and formulation Optimisation of a catfish feed Least cost formulation of livestock and aquaculture diets Formulation of concentrates for various shrimp feed production units.

Development of a low salinity diet. Development of a postlarval feed for shrimp in China. Evaluation of different binders (wheat gluten, Ureumformaldehyde and gelatin) in shrimp feeds. Influence of replacement of wheat flour by Cassava (Tapioca) on pellet quality (water stability, leaching, hardness) of shrimp feeds. Production management Day to day running of a feedmill (5 ton/h) which supplies all the animal feed requirements of Seychelles (feeds for layers, broilers, turkeys, ducks, pigs, cattle, horses, rabbits, dogs and cats). Assistance in design, engineering and upgrading of various feedmills Supervision of the construction and starting up of a silo storage and automatic dosing system for raw materials (capacity 1500 MT) in Seychelles.
