PROBLEM TO BE SOLVED: To provide a method for treating jellyfishes which makes a process in which jellyfish crushing water immediately after crushing jellyfishes is added with a flocculant to flocculate/precipitate a jellyfish flock practicable. SOLUTION: In the method for treating jellyfishes, the jellyfish crushing water 6 which crushed jellyfishes separated from seawater by a crusher 4 is put in a treatment tank 5. The jellyfish crushing water 6 is incorporated with a polychloroaluminum inorganic flocculant PAC (trade name), a neutralizing agent (pH adjusting agent), and an auxiliary polymer flocculant Kuriflock PA-331 (trade name), and the flock of jellyfish organic components contained in the jellyfish crushing water 6 is flocculated and precipitated. By adjusting the amount of the inorganic flocculant to be added to one liter of the water 6 at about 2000 mg/l and the amount of the auxiliary flocculant at about 3 mg/l, the flock is flocculated surely and promptly to be precipitate in the clear jellyfish crushing water 6.
