Thailand 01 (Post two of two) Thailand 02 (Post two of two)




The inserted pictures are a part of the Royal-Inthanon Project located in the mountain area in Chiangmai Province, Thailand whereas project aquaculture includes the farming of rainbow trout (Oncorhynchus mykiss) and Siberian sturgeon (Acipenser baerii) are cultured. Rainbow trout were chosen in the beginning as an experimental fish because its upper lethal temperature is higher than for other Salmon species.

The concrete raceways (2.5x30x1 m deep) shown in the inserted pictures belong to the farming of rainbow trout (Oncorhynchus mykiss) and are located at a height of about 1300 m above sea level on a small tributary stream of the River Klang near the base of Siriphum Waterfall on Doi Inthanon National Park. These raceways are supplied with water from the waterfall at the rate of 250 l/min in the summer season and 500 l/min in the rainy season.

As expected, and based on research findings, water temperature at such elevation in the Inthanon (18-20 ˚C) all year round site is much lower compared to that in the low land and hence was found suitable for all year round and close to ideal from October to March for growing rainbow trout from fingerling until marketable size (250-300 g). Feed used in the project is pelleted commercial seabass feed.

It may worth mentioning that rainbow trout and Siberian sturgeon which have been chosen for the project are not native to Thailand and hence fertilized eggs of rainbow trout were initially imported from Germany and Finland.

This project has been established as the King’s project which aimed to help the poor people who lived in Inthanon Mountain -or other high mountain in the North of Thailand- to develop aquaculture skills for increasing income and protein sources for family household. The shown farm can produce fresh trout, smoked trout and gold caviar (from trout) and black caviar from Siberian sturgeon.
