The purpose of such practice is to reduce\nthe aggressive behavior of tilapia males and hence reduce the possible injuries\nand\/or mortality of females during the spawning season especially when the\nmating takes place in confined places such as hapas or tanks whereas females\ncan be exhausted or experience scale loss that may lead to their death. This harm\nis more frequent when males are much larger than females. The clipping\nof the premaxilla is done using sharp scissors or razors.<\/p>\n\n\n\n<p>As expected, in open pond breeding, the aggressive behavior of males is\nnot common as females usually have more chance to escape such harassment and\nhence the removal of the male premaxilla is not usually required. The same is\ntrue when females are mated with similar-sized males.<\/p>\n\n\n\n<p>The resulting wound should be disinfected using proper disinfectants\nsuch as potassium permanganate or a 10% solution of Betadine. \n\nIt may\nworth noting that the removal of the male premaxilla does not interfere with\nthe reproduction or feeding activities of treated males.\n\n\n\n<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"750\" height=\"419\" data-attachment-id=\"15143\" data-permalink=\"https:\/\/fishconsult.org\/?attachment_id=15143\" data-orig-file=\"https:\/\/i0.wp.com\/fishconsult.org\/wp-content\/uploads\/2019\/09\/Premaxilla-removal-of-tilapia-male.png?fit=1250%2C698&amp;ssl=1\" data-orig-size=\"1250,698\" data-comments-opened=\"0\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"Premaxilla removal of tilapia male\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/fishconsult.org\/wp-content\/uploads\/2019\/09\/Premaxilla-removal-of-tilapia-male.png?fit=750%2C419&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/fishconsult.org\/wp-content\/uploads\/2019\/09\/Premaxilla-removal-of-tilapia-male-1024x572.png?resize=750%2C419\" alt=\"\" class=\"wp-image-15143\" srcset=\"https:\/\/i0.wp.com\/fishconsult.org\/wp-content\/uploads\/2019\/09\/Premaxilla-removal-of-tilapia-male.png?resize=1024%2C572&amp;ssl=1 1024w, https:\/\/i0.wp.com\/fishconsult.org\/wp-content\/uploads\/2019\/09\/Premaxilla-removal-of-tilapia-male.png?resize=300%2C168&amp;ssl=1 300w, https:\/\/i0.wp.com\/fishconsult.org\/wp-content\/uploads\/2019\/09\/Premaxilla-removal-of-tilapia-male.png?resize=768%2C429&amp;ssl=1 768w, https:\/\/i0.wp.com\/fishconsult.org\/wp-content\/uploads\/2019\/09\/Premaxilla-removal-of-tilapia-male.png?w=1250&amp;ssl=1 1250w\" sizes=\"auto, (max-width: 750px) 100vw, 750px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Review: Abdel Rahman El Gamal (Founder of the website) The removal of the premaxilla of bone of the upper lip of tilapia males goes back to the late 1970s.
