Seahorses are one of the fish commodities that have a high selling value because they have a unique shape and are widely used as traditional medicine. The increasing market demand for seahorse exports means that the conservation status of seahorses is currently classified in Appendix II and is restricted in international trade. To prevent this, cultivation efforts are being made to preserve seahorses. Main Center for Marine Aquaculture (MCMA) is the technical implementing unit that carries out seahorse cultivation activities, therefore research was carried out with the aim of comparing the use of two types of seahorses in the production of superior seeds to achieve maximum production. The method for collecting and processing data is by making observations at MCMA. The procedures carried out include container preparation, maintenance, air quality measurements and testing. The results obtained from measuring the Hippocampus kuda of female have an average length of 17.9 cm with an average weight of 13.1 grams and males are 18 cm with an average weight of 17.65 grams. The Hippocampus comes of females has an average length of 16.05 grams with an average weight of 10 grams and males 16.35 with an average weight of 8.7 grams. The survivalrateof Hippocampus kuda parents is 50% and Hippocampus comes 96.30%, while the survival of Hippocampus kuda seeds is 48.74% and Hippocampus comes 90.23%, so the best species to cultivate is the Hippocampus comes type.
