WorldFish has also developed the Abbassa Nile tilapia breeding programme, which it launched in 2002 in Egypt. In its ninth generation this outperformed other local strains by 12 percent in growth rate and 48 percent in profitability because of improved, lower food conversion ratios (Ibrahim, Nasr-Allah and Charo-Karisa, 2019). Department of Agriculture of tilapia allows year-round produc-tion and can be a good alternative to pond or cage culture. Intensive tank culture offers several advantages over the use of ponds. The high density of fish in tanks disrupts breeding behavior and allows male and female tilapia to be grown togeth-er. If cultured together, females will GUIDELINES FOR IMPORTATION AND HANDLING OF TILAPIA SUPER YY BROODSTOCK BY FISH HATCHERY OPERATORS IN KENYA Introduction Tilapia species is the most cultured fish species in Kenya. However, a major constraint in the culture of this fish is its early maturation, prolific breeding, over population, increased competition for food and space. although tilapia can survive acute low do concentrations for several hours, tilapia ponds should be man- aged to maintain do concentrations above 1 mg/l. metabol-ism, growth and, possibly, disease resistance are depressed when do falls below this level for prolonged periods. ph in general, tilapia can survive in ph ranging from 5 to 10 but do … A: There are a few methods in tilapia breeding, but the most common is to use hormones. This method can be used to stimulate reproduction and increase the number of eggs that are produced. Another way is to use temperature changes. The water temperature can be changed by using a heater or cooler, which will change the sex ratio of the fish. (2) Over-winter tilapia farms have gradually developed and expanded tilapia breeding areas. (3) Various culture modes were developed such as pond, cage, flowing water, reservoir, industrialized, etc.. (4) The feed formulation of brooders, seedlings, grow-out and other different breeding stages is more reasonable. 68 23 Tilapia breeding hapas in pond 73 24 Gathering tilapia breeders at regular intervals for egg collection purpose in the breeding hapa 73 25 Plastic vowels placed in a bamboo frame for Breeding is largely driven by social behavior and an understanding or ability to predict dominance, or select breeders with reduced stress responsiveness, can improve hatchery and breeding programs. The physiological and behavioral responses to stress may be used to select broodstock with reproductive advantage. Tilapia as production fish Bream (or Tilapia) is a common name for a group of cichlid fish species, which can be separated in two categories (genus's), namely the mouth breeding or Oreochromis-species, and the non-mouth breeders or Tilapia-species. Tilapia breeding in ponds 1. Prepare the pond Level the pond bottom and rid it of un­ wanted organisms by using chemicals or tobacco dust, rotenone, etc. The pond bottom must slope to facilitate water drainage through an outlet pipe or gate. 2. Fix the acidity of the pond (pH 6.5 - 9) by liming (if needed).
