Effect of Thiourea and Starvation on the Physiological and Biochemical State and the Reproductive System of Climbing Perch Anabas testudineus

详细

The effects of thiourea (keeping of fish for 32 days in 0.05% solution of thiourea) and of starvation (during 12 days) on the physiological and biochemical state and on the reproductive system of mature males of climbing perch Anabas testudineus are investigated. Combination of these two factors results in a decrease in the level of sex steroid hormones (testosterone and estradiol-17β) in blood, in changes in synthesis of thyroxine, in its conversion to triiodothyronine, and in acceleration of spermatogenesis.
