Attempts to commercialize monosex hybrids, usually with the O. niloticus O. aureuscross or using male O. urolepis hornorum with females from O. niloticus or O. mossambicus, have met with varied success. 12. In animal and plant breeding, the term strain is normally applied to intraspecific subpopulations that exhibit distinctive traits, which are normally homozygous or true breeding. Fisheries scientists and taxonomists have changed the name of the tilapia at different times based on different characteristics, especially spawnning and reproductive behavior, as the basis of their research. Triploids have comparable or slightly slower growth rates than normal diploids, but offer the significant advantage of sterility. For Hair.

(Editors Note: This article was originally published in the December 2001 print edition of the Global Aquaculture Advocate.). WebIn light of the potential fish demand driven by population and economic growth in Africa where tilapia is a native species favoured by most consumers, there is little doubt that there is great potential for the development of tilapia As a result, this species appears to be more robust and less prone to problems associated with founder effects. The Advocate aims to document the evolution of responsible seafood practices and share the expansive knowledge of our vast network of contributors. Average weight of the transgenic fish was three to four times that of their nontransgenic siblings (Fig 2), with equivalent or superior food-conversion efficiencies. Due to the demand in the local market and its high market price, farmers are currently cultivating this fish at a higher rate. E.g. Production of 8 10 tons/ha can be obtained in one crop of 6 months.
