The fish in fish-based natural fertilizers is generally obtained in one of two forms: condensed fish solubles (CFS) or enzymatically digested fish (EDF). CFS-based ingredients, or emulsions, use a strictly controlled, pressurized heating process to extract the raw materials necessary to make fertilizer. EDF-based ingredients, or fish protein hydrolysates, are derived from a process that minces the whole fish, then enzymatically digests, then grinds and liquefies the resulting product.

While both forms provide acceptable performance, emulsion-based fertilizers are more concentrated and uniform than hydrolysate-based fertilizers for optimum performance.
