In this study, we estimated the economic profitability of small-scale production of O. niloticus in semi flow-through system at three stocking density using the profitability index and the viability index. Unlock this data. 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. The few studies that looked at crossbreds (i.e., crosses between stocks, within species) have not demonstrated significant heterosis, although crossbreds have been produced to provide a more genetically variable base population for selective-breeding programs. Tilapia contains plenty of vitamin E and B. Vitamin E is well-known to treat skin diseases like eczema. The survey was conducted through face-to-face interview of 467 households consuming fish caught from the lake. 12. The number of eggs depends on the size of the fish. It is also acceptable as an aquarium fish. Tilapias, along with various carp species, catfish and salmonids (which include salmon and trout), dominate fish production from the aquaculture sector. Low calorie 3. This can have a positive impact on energy levels and your overall health. 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. In the Philippines, in terms of annual production these fish are second to milkfish in importance. These techniques have provided useful research tools in the elucidation of sex determination, for example but have not produced outputs of great commercial interest.

Millions of human beings suffer due to hunger and malnutrition, and fishes form a rich source of food and provide a means to tide over the nutritional difficulties of man. Tilapia is one of the most important farmed fish species worldwide (FAO 2018) and an important source of protein (Fitzsimmons 2000;Hai 2015). These are also capable of causing wounds by their spines or spiny opercula. They also have several negative effects, including causing diseases in humans and animals and blighting crops The underside of the head is whitish gray and the upper lip is bluish. 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. O. aureus, or more often its hybrid with O. niloticus, is grown in some regions, due in part to its cold tolerance. Tilapia is also a rich source of potassium and magnesium. Tilapia is an inexpensive, commonly consumed fish that is farmed all over the world. Sabbah explains that in just six months, tilapia tend to yield between 2-300 cubic grams (115-173 cubic ounces) of flesh. The body is covered by cycloid scales and there are 30-32 scales along the lateral line. The most important fishery by-product is that of the fish oil, which is of two kinds- body oil and liver oil. The O. niloticus O. aureus hybrid often produces inconsistent sex ratios, and broodstock contamination can lead to further deviations from predicted sex ratios. Useful Fishes: 1.
