Pisciculture, to increase the fish production, has a crucial limitation. Fish cultured in land-locked water bodies usually do not breed without the hormonal induction. Technology of fish breeding suffered for a long time due to the lack of suitable commercial product to induce the spawning of economically important fish. Hypophysation technique, where pituitary extract was used to induce the br...

The biological aspects for the semen of males (Cyprinus carpio) were assessed during spawning season, after they artificially induced spawning. insemination by injecting with Ovaprim and pituitary gland extract. Two dosages had been used 0.5, 0.3 ml 2,4 mg per Kg body weight respectively. After that volume semen, pH, number sperms in one motility estimated. total obtained from ranged between (7...
