The experiment was conducted to improve the artificial egg collection technique of Marble goby, Oxyeleotris marmoratus by understanding its reproductive behaviour. The experiment was done through observation of reproductive behaviour of the selected brood fish in a 700L aquarium following Human Chorionjc Gonadotropin (HCG) injection. A pair of 0. marmoratus brood fish was selected for each trial and from a total of six trials, three pairs of selected brood fish were successfully spawned. All successful spawning pairs showed similar reproductive behaviour at 26 - 32°C, and the breeding cycle completed within 142 - 165 hours. After hormone injection, male and female started to swim at the bottom and they always separated at least 20cm apart. After male occupied the nest, it started to swim out to court female and lead into the nest. Female that not ready to spawn rejected male without showing response to the male courtship. In the nest, the pairs showed pre-spawning behaviour prior to spawning. For the three successful spawning trials, spawning phase took place within 37 - 74hAI, and parental care also started at the same time. After female left the nest, the male guarded and fanned the eggs until the end of hatching. The results suggest that observation of the reproductive behaviour of O. marmoratus brood fish enables the culturists to predict whether the hormone treated fish will be able to spawn and also to estimate when the spawning will take place. Hence, the artificial eggs collection technique can be improved.
