As a new aquaculture species, silver rasbora ( Rasbora argyrotaenia ) has a high demand for consumption and ornamental fish in Indonesia and its surroundings. The aim of this study was to measured egg diameter in female silver rasbora at different maturity stages. This study was conducted in February 2020 at instrument laboratory Universitas Airlangga, Banyuwangi Campus, Indonesia. A total of 16 females of silver rasbora with a weight of 1.73±0.08 g and length of 5.39±0.13 cm was obtained aquaculture installation of Universitas Airlangga, Banyuwangi Campus, Indonesia. Based on the result, the egg diameters were observed in II, III, and IV maturity stage in the amount of 17.96 ± 1.88 µm, 47.15 ± 10.07 µm, and 83.02 ± 4.40 µm. This information will reach our knowing of the maturation cycle of silver rasbora and also improve artificial techniques of culturing fish for commercial purposes and conservation stocking.
