A method of using phosphate chemicals of the formula LDPO4 to provide controlled release nutrients to the food chain in aquatic environments to supply improved feeding and growth of fish, wherein L represents a monovalent Lewis Acid moiety, D represents a divalent metal moiety, and PO4 represents an orthophosphate moiety. The method includes the use of slow release phosphate chemicals which provide water soluble nutrients disseminating in flowing water streams for a period of about one year. The chemicals include: magnesium ammonium phosphate, manganous ammonium phosphate, zinc ammonium phosphate, ferrous ammonium phosphate, magnesium potassium phosphate, manganous potassium phosphate, and manganous potassium phosphate. |
