Prepare the Protein: Clean the fish fillets and shrimp, removing any bones or shells. Place them in the blender or food processor and pulse until finely minced.

Add Vegetables and Carbohydrates: Add the chopped vegetables, cooked rice, or oatmeal to the blender. Blend until smooth.

Incorporate Nutrients: Add the spirulina powder and fish oil to the mixture. Blend once more until all ingredients are well-combined.

Mix with Gelatin: In a bowl, dissolve the gelatin powder in warm water. Slowly add the blended fish mixture, stirring to create a thick paste.

Form the Food: Spread the mixture evenly on a baking sheet lined with parchment paper. Use a spatula to smooth it out into a thin layer.

Freeze and Cut: Place the baking sheet in the freezer for a few hours until it hardens. Once frozen, cut into small squares, suitable for your fish’s size.
