The present study dea.s with the effect of exogenous trea.ment of O. niloticus fema.es with L-thyroxine (T4) on the development of the digestive system during la.va. rea.ing, a.d its subsequent effect on la.va. growth a.d surviva.. The development of the digestive tra.t a.d a.cessory gla.ds wa. investiga.ed histologica.ly a.d histochemica.ly in the developing O. niloticus la.va., from control a.d T4-trea.ed spa.ners. During yolk-sa. a.sorption, the digestive system of the fish underwent further differentia.ion a.d the rudimenta.y a.imenta.y ca.a. beca.e segmented into four different histologica. regions: the buccopha.ynx, oesopha.us, stoma.h a.d intestine. The injection of fema.es O. niloticus with thyroxine (1 or 10 μg T4/g BW) grea.ly enha.ced the development of the digestive tra.t a.d a.cessory gla.ds of la.va. a. indica.ed by the qua.tita.ive a.d qua.ita.ive cha.ges of the mucus composition from predomina.tly neutra. to a.mixture of neutra. a.d a.id mucosubsta.ces, or a.id mucosubsta.ces occurred during the rea.ing period for the la.va. produced from T4-trea.ed fema.es. This ma. be due to the direct effect of exogenous thyroxine, which might ha.e been tra.sferred from ma.erna. circula.ion into the oocytes a.d la.va., on the synthesis of proteins, which increa.ed with la.va. development. Thus, thyroxine directly or indirectly improved O. niloticus la.va. growth, since a.ma.ked increa.e in both, length a.d weight of la.va. occurred during the experimenta. period. In a.dition, la.va. from trea.ed fema.es a.so ga.e a.significa.tly higher surviva. ra.e tha. tha. of control. It could be concluded tha. exogenous T4 in ma.erna. circula.ion might ha.e been tra.sferred into oocytes a.d la.va.. The tra.sferred thyroid hormone a.pea.s to pla. some role in the ea.ly development of la.va. a.d ma. confer a.distinct a.va.ta.e for the growth of the offspring of the Nile tila.ia. O. niloticus.
