The farm shown in the video is a part of the Royal-Inthanon Project located in the mountain area in Chiangmai Province, Thailand.
The Royal Project which was founded in 1969 aimed to help the hill-tribe poor people who lived in Inthanon Mountain – or other high mountains in the north of Thailand- to become self-supporting and to develop the skills about aquaculture as a means for enhancing household nutrition and increasing income for the target people.
The concrete raceways shown belong to the farm of rainbow trout (Oncorhynchus mykiss) which is located at a height of about 1300 m above sea level whereas water temperature at such elevation is about (18-20 ˚C) which was found suitable for all-year round cool water aquaculture as required for rainbow trout from fingerling until marketable size (250-300 g). The concrete raceways measure (2.5x30x1 m deep). Raceways receive water from the waterfall at the rate of 250 l/min in the summer season and 500 l/min in the rainy season. Feed used in the project is pelleted commercial seabass feed. The shown farm can produce fresh trout, smoked trout and gold caviar (from trout).
It may worth mentioning that rainbow trout is not native to Thailand and hence fertilized eggs of rainbow trout were initially imported from Germany and Finland. The species has been chosen based on their temperature compatibility as well as their production performance and market merit.
