The nutrient content of manures varies. Mesh size has a significant impact on production and should be 1.9 cm or greater to maintain free circulation of water. 250 mm fish ÷ 25 mm = 10. Fertilisation strategies produce fish to a size of 200-250 g in five months. Stocking levels will vary depending on filtration and husbandry however a general rule for stocking is 25 cm of fish per square metre of surface area or 55cms per 1000 litres volume. Dosage for chlorine is 15-20 mg of chlorine per litre of water. Male tilapia are stocked at 1-3 fish/m2 and grown to 400-500 g in five to eight months, depending on water temperature. One advantage is that the fish are able to utilize natural foods. If the pump is carrying the water to a height above the ponds surface to a waterfall for example, then it will encounter "static head". In temperate regions, recirculation systems have been developed to culture tilapia year-round under controlled conditions. A new system that uses AI and IoT technology to automatically measure the size of the fish in aquaculture installations, by using a portable camera paired with a mobile app, has been developed by Umitron. An 8 foot pool with three feet of depth holds a bit over 1,000 gallons. To convert m3 into litres you need to multiply m3 by 1000.The formula for calculating volume is; L x W x Av.
