 Tilapia
|
| Common name: | Tilapia |
| Scientific name: | Oreochromis nicloticus, O. aurea, O. mossambicus, O. hornorum |
| Production potential: | Easy except tilapia grow slowly at temperatures lower than 70 F and die when temperatures drop into the 50 F range |
| Marketing potential: | Potential: High Size: 1.25-2.0 lb Market: Food |
| Temperature requirements: | Growing: 80-87 F Spawning: Greater than 72 Lethal: 55 F |
| Feed requirements: | Protein: 25-30% Fat: 6-8% |
| Spawning requirements: | Maternal mouthbrooders, spawn twice a month, 2,500 eggs/lb body weight, eggs hatch in 5 to 7 days. All male hybrids can be produced by crossing female O. niloticus and male O. aurea.Or by crossing female O. niloticus and male O. hornorum.Stocking ratios for fingerling production is three females to each male. |
| Most common production systems: |
For food fish estimate at 1500-3,000 lbs. per acre. For food fish production in cages stock 8-15 lbs. per cubic food. Stocking densities in recycle systems depends on the quaility of the filtration used. However at harverst a goal of from 0.5-1.5 lbs pounds per gallon is desired. |
