(ii) Fish for controlling diseases: In the Philippines, in terms of annual production these fish are second to milkfish in importance. 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. Consumer response to transgenic fish, which are classed as genetically modified organisms, is also generally negative. This review paper organized with the specific objective of Socioeconomic importance of Fish production and consumption status in Ethiopia. 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. As such they occupy an intermediate position between primary producers and piscivores. At night the fry move in deep water and during the day they form large flocks. Despite many hybridizations, there are few, if any, published studies that clearly demonstrate heterosis for any commercially important trait, with values for such traits in hybrids commonly falling between those of the parental species. What Is Cobia? Their jaws are protruding, their lips are thick and their mouths are wide. Despite the fact that tilapia strains are not easily distinguished by their appearance or properties, several scientific studies have demonstrated that there can be significant differences between strains for commercially important traits, with differences in growth rates of up to 20 percent as an example. The main commercial interest in chromosome set manipulation is in the production of sterile triploids. Phosphorus 4. A mature male tilapia grows to 30-44 cm in length and a mature female grows to about 25-33 cm. Even in largescale commercial operations or stateof- the-art intensive-production systems, due consideration is rarely given to the origin or quality of the stock cultured other than ensuring the correct species is used. Differences in growth rates of a few percent or a 1 percent increase in fillet yield can have significant impacts on the profitability of tilapia culture, especially in markets where profit margins are slim. 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.

The body is covered by cycloid scales and there are 30-32 scales along the lateral line. This fish currently occupies an important place in fish farming in many countries. Although aquaculture genetics lag behind advances in crop and livestock breeding, the current pace of development may narrow the gap appreciably in coming years. Useful Fishes: 1. The female fishes play the role of breeding mates. The body is long, well pressed and rounded. Content Guidelines 2. All the cartilaginous fishes are predaceous and feed chiefly on large quantities of crabs, lobsters, squids and other valuable marine animals. Its popularity among farmers is increasing day by day due to its ability to take natural food, interest in supplementary food, survival in adverse natural environment and high immunity. Crude skins of sharks and rays are used by carpenters and metal workers. Important marine fishes include salmon, cod, halibut, herring, eels, tuna, mackerel, and sardines. They usually breed every 2-3 months throughout the year. They also have several negative effects, including causing diseases in humans and animals and blighting crops As such they occupy an intermediate position between primary producers and piscivores. The canned meat of sharks is sold commercially under the name of gray fish. Bangladesh is one of the world's leading fish producing countries where inland aquaculture contributes 56.44%, and inland capture contributes 28.14%, to total production in 201617 ( Table 1 ). During the breeding season, they build round nests on the edge or bottom of ponds in areas rich in aquatic plants, and the female fish lay their eggs here. ECONOMICS OF FARM UNITS 3.1 Species and culture techniques to be investigated 3.1.1 Species It has 7 grams of protein and 6 grams of fat per 100-gram serving. Tilapia fish survive at 12-40 0 C and grow at 18-35 0 C. It can grow up to 45 cm in length and 1.1 kg in weight with a lifespan of 11 years. The major food fishes of India include Labeo, Catla, Cirrhina, Mystus Wallago, Notopterus, Ophiocepholus, etc. In South Africa the YY-tilapia males are being cultured in some designated areas. Certain fishes and their bye-products contribute to useful Ayurvedic and Unani medicines for treatment of duodenal ulcers, skin diseases, night blindness, general weakness, loss of appetite, colds, coughs, bronchitis, ashthma, tuberculosis, etc. A similar, although slightly simpler, breeding program has been developed to produce monosex male O. aureus, through the production of sex-reversed ZZ females, although this monosex fish is not thought to be in significant commercial production. Illustrations from Egyptian tombs suggest that Nile tilapia were cultured more than 3,000 years ago.
