Guppy fish Poecilia reticulata is one of the most popular freshwater ornamental fish species because it is easy to main-tain, and has beautiful variations of color, especially males. One method to produce male guppy is masculinization me-thod. This study aimed to determine the dose of hormone treatment from visceral organ of sea cucumber to the process masculinization of fish guppy. This study used a completely randomized design with the immersion treatment of parent guppy which has been bred into the extract solution of sea cucumber innards for 24 hours with different doses i.e. 0 mg L-1, 10 mg L-1, 20 mg L-1, 30 mg L-1 and 22 mg L-1 (metiltestosterone as positive control). The parameter measured was the percentage of male fish produced. The results showed that although the effect of the treatment was not significantly different, but it can be said to be significantly different to the treatment of 0 mg L-1 (control) to obtain the best result for masculinization of guppy at 30 mg L-1 immersion and the best survival rate on treatment of 0 mg L-1 (control). The re-sults of this study suggest that the masculinization technology on the parent stock can be done using extracts of sea cu-cumber innards which has been considered as waste.AbstrakIkan gapi Poecilia reticulata merupakan salah satu jenis ikan hias air tawar yang banyak digemari karena mudah dipe-lihara, dan memiliki variasi wama yang indah, terutama jantannya.
