Electrophoretic Pattern of Serum and Yolk Protein With Relation to In Vivo Oocyte Development by HCG Hormone Treatment in Catfish(Silurus asotus)

The egg development of various fishes is studied by various methods including electron microscopy(Matsuyama et al, 1991) and hormone treatment(Schoonbee et al. 1980). In addition to attempt to induce final maturation and spawning, the present experiments were conducted to investigate the influence of hCG upon reproductive cycles in catfish(Silurus asotus) with developing gonads and to stimulate the reproductive system during the rapid phase of gonadal development.
