Transgenic fish have been used to study developmental regulation of genes, improve cold tolerance, increase growth rate, and improve feed utilization. They are not classed as genetically modified organisms, and the technology can be applied in a range of hatchery systems simply by replacing broodfish with YY males, although good broodstock management is required to prevent contamination. The choice of land is crucial to the construction of a pond. Tilapia are some of the oldest cultured fishes, as depicted in line drawings found in Egyptian tombs that date back to 2000 BC. Which is an economic importance of farming with tilapia? Unique amongst the major farmed fishes, tilapia maintains a key role in rural aquaculture improving the welfare of the poorest farmers while at the same time, it is reared in the most high tech production systems and is sold into international markets for up-scale markets. Its popularity among farmers is also increasing day by day due to its ability to take natural food, interest in supplementary food, survival in adverse natural environment and high immunity. Consumer response to transgenic fish, which are classed as genetically modified organisms, is also generally negative. The production of farmed tilapia is among the fastest expanding food sectors in the world. During breeding, male fish make round holes at the edge or bottom of the pond and female fish lay their eggs here. All the cartilaginous fishes are predaceous and feed chiefly on large quantities of crabs, lobsters, squids and other valuable marine animals. The isinglass is a shining powder and is used for clearing wine, beer, making edible jelly and in the preparation of adhesive material. Due to its popularity, there have been more frequent introductions of Nile tilapia into aquaculture from wild African populations.
