  5. 5. Form and Function of Tilapia
  6. 6. Head: • 2 eyes – eyes are rounder because of the refractive index of water. – For view and to detect color. • Mouth located terminally. – Mouth is located at the end of the snout, directly in front of the body. – Takes in food and allows a stream of water over the gills. • paired nasal openings or nares – a blindly ending sac with organs of smell for chemo-reception – to detect odors in water. • gill covers or opercles – assist in moving water over gills and protect gill filaments • Teeth: small, incisor-like; pharyngeal teeth located in back of mouth on roof and floor. – Plant and algae eaters typically have long, fine incisor-like teeth.
  7. 7. Body: • Laterally compressed and deep bodied. – Fish with a compressed shape are flattened from side to side. – able to accelerate very quickly and can move very fast and with great agility for short distances to either escape a predator or catch their prey • An interrupted lateral line – often breaks towards the end of the dorsal fin, and starts again two or three rows of scales below. – for mechanoreception – primarily senses water currents and pressure, and movement in the water • Ctenoid scales, cover entire body – They are rounded, but have small pointed projections (denticles) on part or all of the scale – For protection
  8. 8. • • males: anus (anterior); genital papilla with single urogenital opening at end. females: anus (anterior); genital papilla with two openings, an oviduct and a ureter. Fins: to maintain its position, move, steer and stop : the fins are supported by spines that are rigid and may be quite sharp thus playing a defensive role • • paired fins – pectoral (chest) fin with spines; – pelvic (hip) fins located anteriorly – help to stabilise fish and assist with steering, stopping and hovering. unpaired fins – long spiny dorsal fin – anal fin with spines • reduce rolling motion during swimming and help in turning movements • primarily help fish to not roll over onto their sides – caudal fin: main fin for propulsion to move the fish forward. • homocercal, not deeply forked. – Thin, forked tail fins are for continuous, fast swimming. – Less differentiated tail fins are for less active fishes that may use a short burst of speed to escape a predator or catch a prey.
  9. 9. Within species, coloration is influenced by environment, sexual maturity and food source. T. mossambicus - body yellowish to reddish; weak or no bands apparent on tail fin. T. niloticus - body silver with emerald green tinge; distinct dark vertical lines on tail fin. T. aureus - body white or silver with bluish tinge; interrupted vertical bands on tail. T. hornorum – body black and white; no bands on tail.
  10. 10. Ecological Importance of • They are importance in biological control aquatic plant problems. -most of floating aquatic plants consumed by Tilapia -example:In Arizona tilapia was placed in canal that used for storing drinking water. WHY?
  11. 11. • Reduce spread of malaria by eating the mosquito larvae -Tilapia mariae is primarily a planktivore and an opportunistic consumer of filamentous algae, cyanobacteria, detritus, aquatic plants, diatoms, invertebrates, and fish eggs - it has fine teeth with moveable slender shafts adapted for grinding
  12. 12. The number of native fish may reduced  Tilapia as omnivores Environment changes and competition between Tilapia and native fish. Tilapia able to adapt at new condition. The cage culturing tilapia results in reducing of water quality. contribute to eutrophication. Algae use all the oxygen in the water. This result in the death of aquatic organisms. Some algae can produce toxin that are harmful , affect fish that feeds on them.
  13. 13.  Use nutrient dense diets to minimize wastes by delivering a feed that provides the highest possible incorporation of ingredients to absorption by the fish.
  14. 14. Economic Importance  FOOD SOURCE • Fish has been identified as one of the two most important livestock sub-sectors for future national food security.  AQUACULTURE • Tilapia is a fast growing fish that eats a diet of vegetables and cereal grains, it can be raised for much lower production costs and turn over quicker for a profit.  INTERESTING BYPRODUCT FORM • Interesting byproducts have emerged such as leather goods for clothing and accessories, gelatine from skins for time-released medicines and flower ornaments made from dried and coloured fish scales.
  15. 15.  NUTRITIONAL VALUE • Becoming a popular seafood due to rich source of protein , phosphorus, potassium, selenium, niacin, vitamin B-12 and is low in fat and saturated fat, omega-3 fatty, calories, carbohydrates and sodium.  IMPROVED TILAPIA BREEDS • An improved breed of Nile Tilapia that grows 30% faster than nonimproved strains is helping to increase aquaculture productivity and food security.  DOMESTIC MARKETS • Tilapia production in Malaysia goes almost entirely to the domestic market to support strong local demand. • The certified fish are sold as frozen fillets and loins to North America, Europe and Asia, and as live and fresh in the local market.
