AN EXPERIMENTAL SYSTEM FOR SMALL-SCALE EXPERIMENTS WITH MARINE FISH AND CRUSTACEANS

A small-scale experimental larval rearing unit was designed for contro lled experiments on marine fish and crustacean larvae. The system uses 3 litre hemispherical, black tanks in sets of three with their own bi ofilter. Alternatively the whole system can be integrated to allow the use of 18 tanks. The system has successfully been used for work on th e greenback flounder (Rhombosolea tapirina). The main problems have be en preventing the formation of surface oil films when using live feeds and solid removal at weaning. However the aims of compactness, low co st and versatility were successfully achieved
