Skeletal system deformities in cultured common carp (Cyprinus carpio L.)

Skeletal system deformities were described in common carp as early as the 16th century by French scientist Guillaume Rondelet. Since that time, much research on skeletal system deformities in common carp has been carried out throughout the world. In this investigation, because of the increased prevalence of skeletal system deformities in common carp (Cyprinus carpio L.) on one fish farm in Croatia, and in order to exclude genetic factors as a possible cause of these changes, we placed special emphasis on broodstock selection for artificial propagation. All carp broodstock with determined skeletal system deformities and marked broodstock of the highly selected common carp strain were excluded from further breeding. After the artificial spawning of the broodstock remaining in the broodstock population, deformities of the skeletal system were not noticed in the offspring. In carp fingerlings with clinically visible deformities sampled in the previous years, spinal deformities were examined using radiology, pathomorphology, histopathology, proteomic and X-ray diffraction analysis. Observed changes in carp fingerlings indicate a growth and development disorder in which the genetic predisposition has a primary role.
