referred To In The Bible, Pictured On The Wall-friezes Of Ancient Egyptian Tombs, And A Subject Of Fascination For Generations Of Scientists, The Tilapias (cichlidae: Tilapiini) Have Featured In The Diet And Culture Of Humankind For Thousands Of Years. The Present Century Has Seen Their Spread From Africa Throughout The Tropics And Sub-tropics, Largely For Food And Fisheries Purposes. This Book Attempts To Pull Together Our Knowledge Of This Important Group - Their Biology And Fisheries And Aquaculture - In A Single Volume, Something That Has Not Been Done Comprehensively For Nearly Two Decades. A Succession Of Chapters By Acknowledged Authorities Covers Evolution, Phylogenetic Relationships And Biogeography, Reproductive Biology, Mating Systems And Parental Care, Diet, Feeding And Digestive Physiology, Environmental Physiology And Energetics, The Role Of Tilapias In Ecosystems, Population Dynamics And Management, Genetics, Seed Production, Nutrition, Farming, Economics And Marketing. The Book Is Aimed At Biologists, Fisheries Scientists, Aquaculturists, And All Interested In Aquatic Ecology.
