Summary Cuming's barb ( Puntius cumingii Gunther) is an endangered endemic species of fish in Sri Lanka. A study was carried out on the reproductive biology and breeding of this species in captivity. At maturity, males and females measured 32.6 and 33.1 mm, respectively. In the ovaries, the egg‐diameter distribution pattern indicated the presence of large and small yolked eggs in two groups. Large mature eggs ranging from 0.45 to 0.80 mm in diameter were shed during spawning. Small eggs measurin 0.20–0.45 mm took 7–10 weeks to reach mature size, then were shed at the next spawning. The number of eggs shed per sawning cycle and total fecundity raned from 256 to 976 and from 383 to 1829, respectively. Hatckng rate varied from 5.3 to 97.1 %, with a mean value of 68.3 %. A majority (55 %) of the females completed spawning within 1 day. This investiation indicated that P. cumingii could be successfully reared and bred in captivity; the results would be useful in the development of breeding programmes for this species.
