Effect of lead, zinc, mercury, and copper with and without estrogen on serum vitellogenin level in Magur fish (Clarias batrachus L.).
Injection(s) of lead, zinc, and mercuric acetate decreased the serum vitellogenin content in Magur fish, while cupric acetate failed to cause any change in the vitellogenin level. Estrogen injections on 7th, 8th and 9th d increased the serum vitellogenin level in normal and copper salt treated fish, but were totally ineffective in altering the reduced vitellogenin content in lead, zinc, and mercury salts treated fish. Vitellogenin level almost restored to normal level at 6 week in lead, zinc, and mercury treated fish, and estrogen injections on 37th, 38th, and 39th d enhanced the serum vitellogenin content in all groups.
