Embryo and larvae development of Nilem Fish, Osteochilus vittatus reared in batik liquid waste

Abstract. Nugrahesthi GH, Wijayanti GE, Habibah AN. 2023. Embryo and larvae development of Nilem Fish, Osteochilus vittatus reared in batik liquid waste. Nusantara Bioscience 15: 105-112. The embryonic larval stages are critical phases an organism's development. For aquatic organisms, is affected by environmental factors such as A waste a product the textile industry usually streamed directly into environment. This study aimed to observe effects exposure on developing (Osteochilus Valenciennes, 1842) fish embryos larvae. research was conducted using completely randomized design. One hundred two-celled were kept with dilution concentrations 0% (the control), 5%, 10%, 15%, 20% water until age 4 days after hatching five replications. time embryo evaluation 60th minutes, 120th 180th minutes fertilization; stage 24th, 48th, 72nd, 96th hour evaluated for each replication. results showed that height blastoderm embryo, accumulation chorion deceleration development, increased abnormalities, decreased survival rate larvae, acceleration yolk absorption Embryos successfully hatched produced only control 5% medium. Batik interfered O. generated mortality above 5%.
