When the worms have grown enough, they are put in baskets. From there, they will spin their cocoons in five days and will produce about three hundreds meters of silk each. The cocoons are then put in sunlight to avoid them undergoing their metamorphosis into mature moths. However, 20% of them reach the breeding process and the female moths will lay and hatch its eggs within nine to twelve days.
The cocoons are soaked in hot water in order to soften the sericin (also known as silk gum) which coat the fibres and stick the cocoons together. Silk threads are then unwound and reeled together to produce a single thread. Weavers at Angkor Silk Farm make both raw silk and fine silk that do not have the same texture at all. Sericin has not been completely removed from raw silk threads, which will give a rougher texture to the fabric at the end.
Coho salmon
The eggs hatch in the late winter or early spring after six to seven weeks in the redd. Once hatched, they remain mostly immobile in the redd during the alevin life stage, which lasts for 6–7 weeks. Alevin no longer have the protective egg shell, or chorion, and rely on their yolk sacs for nourishment during growth. The alevin life stage is very sensitive to aquatic and sedimental contaminants. When the yolk sac is completely resorbed, the alevin leaves the redd. Young coho spend one to two years in their freshwater natal streams, often spending the first winter in off-channel sloughs, before transforming to the smolt stage. Smolts are generally and as their parr marks fade and the adult's characteristic silver scales start to dominate. Smolts migrate to the ocean from late March through July. Some fish leave fresh water in the spring, spend summer in brackish estuarine ponds, and then return to fresh water in the fall. Coho salmon live in salt water for one to three years before returning to spawn. Some precocious males, known as "jacks", return as two-year-old spawners. Spawning males develop kypes, which are strongly hooked snouts and large teeth.
