Abstract
   The results of a profitable fish farming are based in the first place, on the genetic quality of fish (growth rate, prolificity, disease resistance, etc.) The genetic improvement of the fish is a continuous preoccupation at the global and national level, intending to create new, highly productive races and hybrids. The morphologic characterization used as an instrument of work in the evaluation of the morphometric changes of fish, is based on biometry. The study presented achieves a morphometric characterization of the tench through the classic biometric method and tests the possibilities of using 3D photographic method for fish measureing. The results show that the classic biometrics method with a high degree of aggression on fish, can be replaced with the 3D photometric method, used through an application on the mobile phone, that achieves better accuracy, saves time and completely avoids the stress and fish losses
