Özet:

 

In this study; induced breeding of the hormone treated Alburnus orontis and Phoxinellus  handlirschi were carried out; embryonic development stages of the fertilised eggs and anatomical and  histological development of the visceral organs of the larvae and 2 month old juveniles were also  determinated under microscope. The breed fish of the A. orontiswere captured from lake Aksehir by  net fishing. P. handlirschispawners were captured from Kizildere river spring by electroshock fishing.  Male and female spawners were kept in the spawning tanks and raffia egg collector were used to  obtain fertilised eggs. At 20°C water temperature; the morula stage was completed 11 hour after  fertilisation. Formation of the head, axial skeleton and tail were observed 50 hours later. The larvae  hatched 72 hours later. The total length of the newly hatched larvae was 5 mm and 1.1 mg in weight.  Opening of the mouth, and anus and the yolk sac resorbtion of the larvae were completed 3 days after  hatching. Although at the same water temperature morula stages were observed in the P. handlirschi  eggs 14 hours after fertilisation. The germ ring was development in 30 hours, the development of  head, axial skeleton and tail were completed 45 hours after fertilisation. The larvae hatched after 72  hours. Total length of the newly hatched larvae was in 4.4 mm, and 1.57 mg in weight. Opening of  the mouth and anus of the larvae were also two days delayed according to the larvae of A. orontis.  Oocytes were developed in the ovarium of the two months old aged P. handlirschi juveniles; but the  early development of the gonads were observed in the A. orontis juveniles.
