Annual output, harvest size and growth rate set how many fish are in the tanks at any time. This is the standing stock, and the tanks must hold it at a density the species tolerates.<\/p>\n
Standing stock divided by the planned stocking density gives the culture volume. Splitting it into tanks depends on the species, the building and how you plan to grade and harvest.<\/p>\n
Feed rate depends on species, size and temperature. The peak daily feed is the most important number in the design: it sets the load on every treatment stage. Extension guides describe the same order: the harvest sets the standing biomass, the biomass and feeding rate set the peak daily feed, and the feed sizes every treatment stage (SRAC<\/a>).<\/p>\n A common rule of thumb is about 350 g of oxygen per kg of feed for the fish (Novair<\/a>). The biofilter and organic matter use more on top.<\/p>\n The flow through the tanks must bring enough oxygen and carry waste out fast. Flow also sets the size of the drum filter, pumps, pipework and UV.<\/p>\n Each stage is then sized on the flow and load it carries, at the peak, with standby units where a failure would harm the fish. See cara memilih peralatan RAS<\/a>.<\/p>\n The last step is to check that every stage agrees: the same flow, the same feed load and enough margin at the peak. This flow balance is what we send with every first layout.<\/p>\n4. Feed to treatment load<\/h2>\n
