%X ABSTRACT   SITI HAMISAH MAHARANI. 2024. Addition of Chlorella vulgaris Meal to   Feed to Reproductive Performance of Oryzias woworae Fish. Supervised by   Muh. Herjayanto and Dodi Hermawan  Oryzias woworae is a potential ornamental fish commodity, but only a few in mass   production quantities. Increasing mass production can be done by feeding to   enhance reproduction. Adding Chlorella vulgaris powder could improve the   reproduction of O. woworae. C. vulgaris is a unicellular algae widely used as a   natural feed. C. vulgaris contains carotenoids and vitamin E, a natural antioxidant   that suppresses oxidative stress. This study aimed to evaluate the addition of C.   vulgaris flour in feed for the reproductive performance of O. woworae. This study   was conducted from August to September 2022. Supplementation dose of C.   vulgaris flour was 0%, 5%, 10% and 20%. After the container was prepared and the   feed was made, broodstock was reared in a spawning container, with one male: 1   female ratio. The spawning process takes ten days. Research results show that   adding C. vulgaris flour did not significantly impact the reproductive performance   parameters of O. woworae. However, treatment C (10% of C. vulgaris) produced   more eggs (203 eggs) with a lower additional cost (Rp10,000) compared to   treatment D (20% of C. vulgaris). While treatment D did result in a slightly higher   number of larvae (54 larvae), the cost was higher (Rp20,000) due to the increased   requirement for C. vulgaris. Therefore, treatment C, with higher egg production and   lower costs, is more economically advantageous.  Keywords: Chlorella, feed supplementation, ornamental fish, ricefish
