Anchovies are mixed with coarse salt in large wooden vats and left for months, up to two years at one Kampot maker, while the fish break down into a clear brown sauce. The liquid is drawn off, and Wikipedia describes a final ripening in jars in the sun.
A short entry: the sources we found record only what is said here about Tuk trey itself.

Anchovies or other fish
FAO describes the traditional product as anchovy sauce; one Kampot maker uses a fish known locally as kak koeum[fao2004][ppp2021]

At a glance
Anchovies are mixed with coarse salt in large wooden vats and left for months, up to two years at one Kampot maker, while the fish break down into a clear brown sauce. The liquid is drawn off, and Wikipedia describes a final ripening in jars in the sun. Made in 4 steps over 2 years. The longest step, ferment in the vats, takes up to 2 years (Hom Phanet 2021).
Tuk trey is the Cambodian sea-fish sauce, made in only a few factories on the Kampot and Sihanoukville coast. Unlike prahok, Cambodia's freshwater fish paste, it is a clear liquid like Thai nam pla.
Roe fish sauce (Kampot)One Kampot producer adds fish roe (reported by Wikipedia, citing a book on Cambodian cuisine).
Sweet fish sauceDipping sauce made from fish sauce with sugar, lime juice, chilli and crushed peanuts (reported by Wikipedia).
Safety
Codex requires fish sauce to hold at least 200 g/L salt and no more than 40 mg histamine per 100 g, and to be made from fish fit to sell fresh. Cambodia's fish sauce standard (CS 005:2003) is mandatory, but a 2015 UNIDO review found that it did not set a histamine limit.
An FAO review of Cambodia's marine fisheries (2004) counted three marine fish sauce factories, one in Kampot and two in Sihanoukville, down from several a decade earlier as anchovy catches fell. Cambodia's fish sauce standard (CS 005:2003) is mandatory, and in 2021 Kampot fish sauce was reported as a possible geographical-indication product.
