W. Va. Code R. § 61-27-3
Research has shown that manure from fish, commonly known as aquatic waste, is similar in its chemical composition to other livestock manure and should be treated in the same manner when land applied as a source of agriculture fertilizer. Therefore, the Commissioner recommends that commercial fish operations, federal agencies, state agencies or non-profit organizations dealing in aquaculture research or the production of aquaculture for the benefit of the citizens of the state use the generally accepted best management practices for nutrient management. Best management practices include, but are not limited to, soil testing every three years for areas of application, applying manure at recommended rate, testing manure at least every two years, or not applying manure on frozen ground.
