Description
In summer of 1972, Pomacentrus nagasakiensis TANAKA bred in the small aquariam in the labolatory. Two 60 lit-acrilite tanks with the circulating devices were used. They were preliminary set for spawning by some rocks and coral blocks. Two pairs of the fishes were selected from the specimens collected at Sakurajima in Kagoshima bay. One of the pairs lived together for 66 days, and bred 18 times, and the other for 20 days and 4 times. In the aquarium the male showed some agressiveness, but the territory kept by him was narrow around his nest. Spawning occured with the intervals of 3 or 4 days. Eggs were deposited underside of ceiling of the nest cave and were fertilized immediately by the male. The shape of egg was ellipsoid, measured about 2.3×1.1mm. Incubations took about 3 and half days at 27~29°C. Throughout the period the eggs were guarded only by the male. The eggs hatched at evening soon after the sunset. The larvae were cultured in a 500 lit-tank, feeding with fertilized eggs of Heliocidaris, Brachionus plicatilis and Artemia naupli. After 15 to 20 days they became benthic. But all of them died within a month after hatching.
