The fish Helostoma temminckii, commonly known as the kissing gourami (Fig. 6.1), is recognized by various local names depending on the region in Indonesia. In West Java, it is called “terbakan,” while in Central Java, it is known as “tambakan.” Other names include “sapil” in South Sumatra, “tambakalang” in Jambi, and “poni” or “biawan” in Kalimantan. The kissing gourami is a significant local freshwater species with strong potential for aquaculture development. This species is particularly well-suited for aquaculture due to its ability to tolerate low-oxygen environments (Efriyeldi & Pulungan, 1995). As an herbivorous fish, it reduces reliance on commercial feed. It also has a high fecundity rate, making it valuable for both consumption and ornamental purposes. Despite this potential, the production of kissing gourami still relies heavily on wild populations (Kottelat et al., 1993). The population is facing a decline due to overfishing. According to Gustiano et al. (2015), the kissing gourami is one of 16 local freshwater species that holds significant promise for future aquaculture development.
