Dadzie, Stephen; Hyder, Mohamed (University of Nairobi, 1976)In Tilapia aurea unilateral ovariectomy resulted in a compensatory hypertrophy of the remaining ovary. The compensatory hypertrophy is manifested by: (a) an increase in the number of dividing oogonia; and (b) hypertrophy ... -
Methallibure studies on Tilapia: II. Effect of tilapia pituitary homogenate (TPH), human chorionic gonadotropin (HCG) and testosterone propionate (TP) on the testes of Methallibure-treated Tilapia nigra
Hyder, Mohamed; Shah, Aruna V.; Campbell, Carolyn M.; Dadzie, Stephen (University of Nairobi, 1974-07)In Methallibure-suppressed T. nigra testes high and low doses of TPH and HCG stimulate a qualitatively similar reactivation of spermatogenesis resulting in a significant elevation of testicular weight and G.S.I.; interstitial ... -
Species combination in tilapia culture
Dadzie, Stephen (University of Nairobi, 1982)Preliminary determinations for the best species combination for the fastest rate of growth of Tilapia nilotica (Saro therodon niloticus) and T. zillii indicated that T. nilotica grew better (1.3 g/day) when raised with T. ...
