Tilapia is ranked in the top three in aquaculture worldwide. production over 3,500,000 tons and increases annually. Because of their protein content, large size, fast growth and palatability, Tilapia are the has been the centre of any aquaculture efforts.
Tilapia are easy to farm. They are also the most profitable fish in aquaculture due to their mode of reproduction, ability to live in cramped conditions, and fast growth. In some places the fish are raised in rice fields during planting time and grow to large sizes (12-18 cm) by the time rice is ready to be harvested. Salmon rely on rich protein feeds which are based on either fish or meat. Commercially farmed tilapia eat vegetable or cereal-based diet.
Tilapia that are grown in inland tanks as well as channels are considered quite environmentally safe, because their waste and disease is contained and not spread to the wild.
Commercially grown tilapia (tillipines) are almost all male. Being fruitful breeders, female tilapia whether in the ponds or the tanks will result end in a large population of small fish.
Tilapia is also processed into skinless and boneless (PBO) fillets: yielding 30% to 37%, depending on the fillet size and the final trim.
The key to any Tilapia farming at your home is something called the “breeder colony”. Large-scale tilapia farming involves the following three species: O. aureus, Oreochromis niloticus, and O. mossambica. Of these tilapia species the one with recognized potential in aquaculture, the Nile tilapia, is the most common in tilapia farming. In some countries, hybrids of 2-4 species of tilapia are also quite popular.
Growth strategies can range from simple to very complex. Relatively simple ones are low in control over the water quality and the food supply. Also by the low farm yields.
In traditional pond tilapia farming, the proper environmental conditions can be maintained through maintaning the balance between the inpus of feed with the natural capacity of farm environment. A fish farm’s natural biological productivity then serves as both a food source and biological filter that helps convert fish waste by-products through natural processes. Increasing the fish stocking densities will place increasing demand on the fish production system. Further energy input in form of labor and water exchange, along with aeration and greater quality fish feeds will all be required to sustain fish culture conditions. As the farm’s production intensifies and the fish feeding rates increase, and also supplemental aeration, the water exchange will be required to maintain a good water quality. Fish stocking densities that are above a 1.5-kg per sq. mtr, aeration is required. Eventually, a final point where any incremental returns on investment cannot be worth the incrementally higher rated of production relative to the higher costs and higher risks. Therefore, increasing the amount of intensity of the fish culture system will not necessarily, (as we have seen) reflect on an increase in total profits.
There are many benefits to be gained from tilapia farming. Tilapia farming can earn a considerably large amount of income from a carefully managed fish farming system.
