Rainbow Trout

Requirements

Rainbow trout require well oxygenated cold freshwater such as those coming from mountain streams. Dissolved oxygen level must not fall below 5.0 ppm therefore, during summer time, air stones or paddle wheels may be needed as the temperature rises since DO is proportional to temperature. They grow best in well aerated, 15℃ freshwaters with pH level at 6.7 to 8.2.

Growing

Rainbow trout are carnivorous fish, generally they feed on aquatic and terrestrial insects, snails and small fishes. If given a formulated diet, it should contain 40-50% protein and be fed twice a day (one in the morning and another one in the afternoon). Moreover, water quality must be maintained all throughout the rearing period and it is best to have a pump ready.

Harvesting

They can be harvested through nets (seine) in case of mass culture.
