The study deals only with the aquaculture engineering aspects regarding system production and maintenance, without focusing on the investment cost. The diameter of the floating aquaculture cages is 20 m and the height is 10 m. From the calculations, it resulted that the rearing density is 15 kg / m3. The annual production provided by the aquaculture floating cages plant is 568 tons / 12 months if the starting culture of sea bass will be about 10g. The production from a single floating cage is 47,339 tons. Starting from the fourteenth month of culture the investor will harvest this quantity of fish for each month. Considering the normal losses that may occur during the fattening phase, the investor should purchase 184621 juvenile individuals weighing 10 g previously vaccinated against major bacterial diseases (Vibrio and Pasteurella polyvalent vaccine) every month. The mesh size of the culture net should start with 15 mm for individuals from 10 -40 g and 25 mm for individuals over 40 g. Keywords: floating cages, seabass, biomass, fattening. |
