    Effects Of 17ß-Estradiol On The Reproduction Of Green Catfish (Hemibagrus Nemurus, Bagridae)
    (2018-02-13) Aryani, Netti; Indra, Suharman
    The aim the research is to increase the reproductive potential of H.nemerus female that is time matured gonads, somatic ovi index, fecundity, egg diameter, hatching rate and time to hatching in the control group (injection 0.9 NaCl) and exposed to 200 μg/kg, 400 μg/kg, 600 μg/kg body weight of 17ß-estradiol. Treatment of 17ß-estradiol levels were significant (p<0.05) different with respect to time ripe gonads, ovi somatic index, fecundity and egg diameter. Females exposed to 400 μg/kg body weight of 17ß-estradiol can increased time matured gonads 28 days, somatic ovi index 10.32%, absolute fecundity 63,724 egss/spaw, relatif fecundity 90 eggs/ g gonado weight and egg diameter 1.22 mm. But hatching rate and time to hatching did not differ between the treatments (p>0,05)
