The male and female ratio of was 1:1, Centropyge acanthops was stocked in 250 liters of PP tanks with artificial feed, and the eggs were collected and calculated to carry out the breeding test of the larvae. The Spawning period of C. acanthops was from June 26 to November 1 and lasted 129 days, including 125 spawning days. The total eggs was 319,433顆(49.91g), including 217,234 buoyant eggs(68.01 %) and 102,201 sinking eggs (31.99 %). The average daily spawning number was 2,555 ± 1,143, about 6,400 eggs per gram. During the period, the water temperature was 25.5 - 27.7 ℃. There were 6 pairs of spawning more than 10,000 eggs. The spawning amount of these 6 pairs was 303,812, accounting for 95.11 % of the total. Among them, pair F1 laid 70,834 eggs, followed by pair F7 with 62,686 eggs. The rate of buoyant eggs was the highest in pair F7 (87.48 %) and lowest in pair F14 (47.08 %). The highest average number of eggs laid per day was 571 ± 349 in pair F1 and the lowest was 272 ± 168 in pair F3.
The eggs of C. acanthops was obtained from spontaneous spawning of the broodstock fish in captivity and incubated at 26.0 -26.5 °C throughout the study. Fertilized eggs (n = 30) of C. acanthops is transparent, spherical and pelagic; the mean diameters of the eggs were measured at 0.65 ± 0.02 ㎜ for C. acanthops.
The first step in establishing artificial reproduction technology is that the seed fish of C. acanthops spawns continuous in an artificial environment. The buoyant rate of fertilized eggs exceeds 60% shows that the maturity of breeding fish is at a similar level with feed nutrition. According to the preliminary baittest, oyster fertilized eggs and ciliates can be fed. Combined with another bait purification technology, a stable breeding technology platform can be established in the future to achieve the purpose of promotion.
