Nearly all fish freshwater and marine are edible and have been an important source of protein, fat and vitamins A and D since time immemorial. Virtually all reports of hybridization show that hybrids within and between the tilapia genera are viable, indicating the speciation within the tilapine fishes may be relatively recent. Our mission is to provide an online platform to help students to discuss anything and everything about Zoology. Tilapia Fish Farming. The ease of handling and domestication of tilapia, together with their reproductive characteristics and relatively short generation time, make them an ideal species for further research.

Some important edible fish of India are given in the Table 9.7 & 9.8. Tilapia fish is a great protein for the body, which in addition to being low in fat and high in Omega 3 fatty acids, also contains Vitamin B12 and niacin. Hybrids involving O. hornorum are not widely cultured, despite the consistency of monosex sex ratios, due to the relatively poor growth performance of the species. E.g. Some tribal people used skins of puffer and porcupine fishes {e.g., Diodon) for war helmets. Both native as well as foreign fishes are displayed in home aquaria for their beauty and graceful movements. Mature males have long jaws with 3 rows of scales. It can generate electricity up to 600 volts in potential with a maximum output of 1000 watts. A program in Cuba has produced a true-breeding line, transgenic for a tilapia growth hormone gene, in an O. u. hornorum-based hybrid tilapia. It is commonly considered that O. niloticusis the best tilapia species for tropical freshwater culture, while O. mossambicus and its hybrids have benefits in brackish water. Just ask the Egyptians, whove been farming these fish for thousands of years. It accounted for 85 percent of the total tilapia production of 1.85 million metric tons (MT) reported for 2000, which was valued at U.S. $1.5 billion. Illustrations from Egyptian tombs suggest that Nile tilapia were cultured more than 3,000 years ago. Liver oil contains vitamin A and D, while the body oil contains them in traces. Tilapia expressing extra copies of trout growth hormone gene grow much faster than their non transgenic counterparts which do not possess extra copies of the growth hormone gene.

For preparing body oil, fish are boiled in large quantity of water. Due to their ease of breeding, tilapia are often maintained as reproductively isolated populations, with the result that inbreeding, genetic drift (random genetic changes), and unconscious selection can impact their genotypic and phenotypic properties. Due to its popularity, there have been more frequent introductions of Nile tilapia into aquaculture from wild African populations. Today, with the application of genetics in aquaculture still in its embryonic stages, more careful choices of strains and improvements to basic broodstock management practices can bring significant increases in returns to commercial tilapia producers. This is the most successful sex reversal programme which has had a significant economic impact on tilapia culture (El-Sayed 2019). Tilapia fish survive at 12-40 0 C and grow at 18-35 0C.
