Osphronemus goramy of the family Osphronemidae is originally living in freshwater bodies of Southeast Asia. By now, it has been introduced into Europe, Australia, and India. Despite its slow growth and low fecundity, it is being assumed suitable for farming due to its air breathing, which makes it withstand low oxygen levels in ponds, and the possibility to thrive on a mostly plant-based diet. Farming has probably been done for hundreds of years and has increased in intensity, while the wild stocks have decreased. A main caveat in production is the large variation in reproduction partially assumed to be caused by unfavourable sex ratios, but non-invasive sexing might be one way of improvement.
For O. goramy to increase its FishEthoScore, more research is needed on the biology and on natural conditions of home range, depth, migration, reproduction, aggregation, aggression, substrate, as well as on water parameter requirements, stress, and stunning. High mortality in larvae and fry stage and decrease in reproduction in spawners might be reduced by moving hatcheries and broodstock facilities inside to protect them from sun and rain, predators, disease, and noise and to better control water parameters.
Note: Due to reaching maturity after the typical age and weight at slaughter, there is no age class "Adults" in the profile.
