| Summary: | © 2016, Universidad de la Frontera. All rights reserved. Mandibular deformity is a condition that affects the jaw bone of adult salmon and has been observed in Norway and Chile, causing weight loss, poor quality of farmed fish and increased mortality. The causes range from high temperatures of the state of eggs, to poor nutrition phosphorus or vitamin C. This work aims to analyze this deformity by histochemical and mineral analysis technique during an episode presented in centers of the Scotia Sea. Jaw and spinal segments of 21 Atlantic salmon in Scotland were used. These samples were classified into three groups: Group 1: Severely deformed. Group 2: Mildly affected. Group 3: Normal controls. Four jaws per group were fixed in 10 % formalin and embedded in Paraplast, sections of 5 microns were performed using a Microm® microtome histochemical technique Von Kossa was used for the detection of calcium deposits, which highlights the calcium osteoid black and red color.
