The Phetchaburi Aquacultic Demonstration Farm is yet another Royal Project. Apart from wonderfully laid out gardens, a pond with bridges and pavilion there are a number of storage tanks with quite sophisticated water circulation systems producing high salinity. Inside the tanks there are some examples of the colourful and exotic marine fish that are found around the coast of Thailand. This is clearly an experimental station with a number of studies taking place. One tank appears to be an attempt at rejuvenating coral.
