Title

The Effects of 11-ketotestosterone Implantation on Biochemical and Hematological Parameters of Previtellogenic Cultured Great Sturgeon (Huso huso)

Pages

  350-362

Abstract

 Understanding the reproductive regulation in sturgeon is a precondition for controlled Reproduction. Although 11-ketotestosterone (11-KT) has been found in blood of female in several fish species, the importance of this Androgen in great sturgeon female has not been investigated. To address this issue, the effect of 11-KT on previtellogenic Huso huso was examined for the first time. A total number of twelve fish (mean weight 5, 580± 165 g) were divided into two circular tanks and reared under natural conditions (natural river water with a natural temperature profile). The fish were surgically implanted with slow-release pellets containing only a carrier matrix (95% cholesterol, 5% cellulose) without or with 2. 5 mg 11-KT. Changes in the plasma levels of hematological and biochemical parameters were evaluated three weeks and two months following implantation. The results showed that red blood cells and its related parameters and white blood cells were affected significantly (P<0. 05), while other hematological parameters were not affected. Also, after three weeks, biochemical parameters including glucose, albumin, calcium, phosphorus, alkaline phosphatase activity, HDL and VLDL in fish which treated with 11-KT implant were decreased and the amount of cholesterol was increased, but after two months all biochemical parameters were increased that increment of cholesterol and HDL was significant (P<0. 05). The results showed that an 11-KT implant can affect fish physiological parameters. Also, 11-KT has positive effects in order to sexual maturity promotion and ovarian development in previtellogenic female great sturgeon.
