Primary Examiner:Lander, Ferris Attorney, Agent or Firm:Young & Thompson
Claims:What is claimed is:
1. A method of producing an organic fertilizer by using fish, said method comprising the steps of preparing a raw material containing more than 80% of fish heads, boiling the raw material to obtain a stock, removing solids and oil contents from the stock to obtain stock liquid, thereafter treating the stock liquid in a decomposition tank with decomposing enzyme for enzyme decomposition, filtering the enzyme-decomposed stock liquid to produce a clarified liquid organic fertilizer, and condensing the clarified liquid organic fertilizer to produce a condensed organic fertilizer.
2. The method as claimed in claim 1, further comprising the steps of drying the condensed organic fertilizer to produce a dried organic fertilizer.
3. An organic fertilizer produced by the method comprising the steps of preparing raw material containing more than 80% of fish heads, boiling the raw material to obtain a stock, removing solids and oil contents from the stock to obtain a stock liquid, thereafter treating the stock liquid in a decomposition tank with decomposing enzyme for enzyme decomposition, filtering the enzyme-decomposed stock liquid to form a clarified liquid organic fertilizer, and condensing the clarified liquid organic fertilizer to produce a condensed organic fertilizer.
Description:BACKGROUND OF THE INVENTION
The present invention relates to a method of producing an organic fertilizer by utilizing fish, particularly heads of fish such as bonitoes and others as raw material.
A fish, particularly the head of fish, contains organic nitrogen (amino acids such as lysine, asparagine, glutamine, sertine, tyrosine, proline and the like), nucleic acid,
