COMPARATIVE STUDY ON THE HORMONAL STIMULATION STERLET (ACIPENSER RUTHENUS, LINNAEUS, 1758) USING CARP HYPOPHYSIS AND ARTIFICIAL HORMONE TYPE NERESTIN 5-5A

Abstract

Starting from the particular sturgeon reproductive biology, propagation of technology through artificial comprises a number of phases required including: selection, parking broodstocks cell maturation and sexual stimulation in order fertilized their conditions provided. To stimulate the process of sexual maturation of the sexual elements for sterlet could be hypophysis and also analogue gonadothropic hormone type Nerestin 5. Literature attesting to the use of sterlet dry hypophysis treated with acetone (Maria Caloianu-Iordăchel, 1973) and employing successful hormone analogue found as LHRHa (N.Patrichi and collaborators, 1989- unpublished data).
