What is the difference between coelomic fluid and vermiwash?

In my opinion and the way I practice, earthworms are directly (known weight of earthworms) are added to a tray containing known volume of luke warm water(37 to40C) and agitated for about 30 to 60Sec. The heat shock makes them to throw out the coelomic fluid through dorsal pores and the mouth in to tray. T he earthworms are collected back and added in to other tray containing water at room temperature. This helps them to overcome shock and the fluid sticking to their body mixes with the water. Earthworms will be safe and can be left back in to their bins. Mix the water in two trays and this will be the vermiwash or it is coelomic fluid in diluted form. As one is washing the earthworms in water, it is called vermiwash.

Coelomic fluid can be collected dirctly from the coelomic cavity by subjecting earthworms to cold shock or mild electric shocks. This is carried out to understand various components in coelomic fluid for scientific investigations.

Vermiwash can be used as spray in nurseries.
