It is estimated that less than 10% of marine ornamental animals sold in the world are originated from captive production. During last decades aquarium trade also have a negative impact on the coral reef ecosystem with the unsustainable capture of wild organisms. In this way, it is recommended the use of specimens produced in captivity. This approach reduces the utilization of natural resources, and in addition fish reared in captivity are most adapted to live in aquaria and less susceptible than wild fish.
The aim of this study was to evaluate the reproductive behaviour and embryonic development of the Orchid Dottyback (Pseudochromis fridmani) one of most popular species of ornamental market. After the establishment of three breeding pairs, each one was isolated to record the courtship behaviour, spawning period and the number of eggs produced.
Results showed that this species is a demersal spawner, presenting parental care. The female laid a thread and the male encircles the eggs while fertilize them, creating one egg ball with approximated 1500-2000 eggs. At 28 ± 1 ºC the Orchid Dottyback spawned every 6 to 7 days. Each egg was an averaged diameter of 1,014 ± 0,227 mm. The embryonic developmental period lasted 4,5 days and newly hatched larvae had an average length of 2,43 ± 0,31 mm.
Although further studies are required to the optimization of the culture conditions for Orchid Dottyback, this study provides for the first time technical information about breeding of this species.
