Tinfoil barb, Barbonymus schwanenfeldii (Bleeker, 1853), is a freshwater cyprinid native to Indonesia, valued both as a food fish and ornamental species. In local markets, its price ranges from IDR 25,000 to 40,000 per kilogram. Morphologically, the tinfoil barb is a deep-bodied species with a silvery-golden body and red fins; the dorsal fin bears a black-tipped blotch, while the caudal fin is deeply forked and marked with a submarginal black stripe. Domestication studies on this species have primarily focused on broodstock selection, hormonal induction, hatchery methods, and nursery culture. These studies have demonstrated the feasibility of spawning and rearing this species outside its natural habitat, while also exploring strategies to improve growth, survival, and feed efficiency. Despite this encouraging progress, several challenges remain to be addressed. This chapter reviews current developments, highlights the main constraints, and outlines future opportunities for the domestication and aquaculture of tinfoil barb in Indonesia.
