In adult salmon of the sea centres in southern Chile, a jaw deformation (JD) has been identified. It affects the dental and hyomandibular bones, which bend ventrally up to 90° of their normal position. The deformation affects also the dental articular bone. This pathology is related to weight loss and increased mortality of the salmons. It was empirically postulated that a probable cause for this anomaly was food from vegetal origin in the diet of the fishes (which are carnivores) Therefore, the present work aims at comparing the biostructure of jaw bone of salmons fed either with vegetal (soja and gluten) formulation or animal formulation, mostly fish powder. Fifty specimens were analyzed from Puerto Montt, 35 having JD and 15 normal control.... |
