This invention relates to a process for the production of dried earthworm powder, as well as antihyperlipemic, antidiabetic and blood pressure regulator (antihypertensive and/or antihypotensive) preparations containing the dried earthworm powder as the active ingredient. More particularly, it relates to a novel and improved process for the production of pharmaceutically acceptable dried earthworm powder which has not only excellent antihyperlipemic, antidiabetic (or hypoglycemic), antihypertensive and/or antihypotensive effects but also a high degree of safety, as well as antihyperlipemic, antidiabetic and blood pressure regulator (antihypertensive and/or antihypotensive) preparations containing the dried earthworm powder as the active ingredient. Thus, the dried earthworm powder produced by the process of the present invention may be combined with pharmaceutically acceptable carriers to form pharmaceutical compositions which are useful for the treatment or prevention of hyperlipemia, diabetes, hypertension and hypotension in mammals and, in particular, human beings.Dried earthworm meal derived from the species was nutritionally evaluated as a replacement for herring meal in production diets from rainbow trout,Increasing levels of dried Sun Dried Earthworm, from 5 to 30% by weight, were included in the diet and the response of fish fed these diets was compared to fish fed a control diet without earthworm meal inclusion. There was no evidence of any adverse effect on the growth performance or feed utilization efficiency of fish fed diets containing these low levels of dried Sun Dried Earthworm. There was. however, a significant increase in the whole carcass lipid content of fish fed diets containing 5. 10 and 20% dried Sun Dried Earthworm.

Sun Dried Earthworm researchers want to find out whether the amount of time earthworms are allowed to acclimate to soils before encountering drought stress affects their survival. If an ideal length of time for acclimation can be found, efforts to establish earthworms may be more successful. Then even drought-prone, dryland soils could reap the benefits that worms provide to other soils throughout the world.
