This research was conducted by an experimental method using a completely randomized design (CRD) factorial with 2 factors and 3 levels of treatment and repeated three times. The material used is silk worms obtained from collectors.
The media used in the research is a mixture of mud, dung quail, pulp, bran, sand and EM4. This study was conducted in 26 March to located at Jln. This study aims to determine the effect of stocking density and feeding tofu to a different frequency on the growth of silk worms. They usually inhabit the bottom sediments of lakes, rivers, and occasionally sewer lines and outlets.Silk worms are one type of live food favored because it has nutrients that are good for the growth of fish larvae.
Encystment may also function in the dispersal of the worm. tubifex can survive drought and food shortage. By forming a protective cyst and lowering its metabolic rate, T. They can also survive in areas heavily polluted with organic matter that almost no other species can endure. The worms can survive with little oxygen by waving hemoglobin-rich tail ends to exploit all available oxygen, and can exchange carbon dioxide and oxygen through their thin skins, in a manner similar to frogs. Micro-plastic ingestion by Tubifex worms acts as a significant risk for trophic transfer and biomagnification of microplastics up the aquatic food chain. These worms ingest sediments, selectively digest bacteria, and absorb molecules through their body walls. Tubifex probably includes several species, but distinguishing between them is difficult because the reproductive organs, commonly used in species identification, are resorbed after mating, and because the external characteristics of the worm vary with changes in salinity.
Tubifex tubifex, also called the sludge worm or sewage worm, is a species of tubificid segmented worm which inhabits the sediments of lakes and rivers on several continents. Tubifex, in Aa River (north of France) in a polluted zone, circa 1990
