The photo shows the concrete tanks used in the spawning of Nile tilapia, Oreochromis niloticus<\/em> as well as the controlled collection of fry and broodstock handling. Tanks are rectangular with 3 x 8 meters while water depth could be adjusted depending on activities. During the spawning, each tank is stocked with 30 females and 10 males with average weights of 150-250 g. However, when ponds are used for holding the broodstock during the resting period outside the spawning season, the number of fish stocked in each tank could increase to 100-150 fish regardless their sex.<\/span><\/h1>\n
