Drain canned salmon and scrape the meat into a blender, along with the fresh blueberries. Puree until smooth. Set aside.
Pour 1/4 cup water into a small pot and turn burner onto medium-high heat. Let this go until it starts to bubble. Since there isn't much water here, it will only take about a minute.
Reduce flame to low and pour salmon/blueberry mixture into the pot. Stir consistently for 1-2 minutes. The goal here is to heat up all of the ingredients.
Pour mixture into a mixing bowl. Add gelatin powder and stir well for 1-2 minutes. The gelatin powder needs to fully dissolve and be evenly spread in order for your treats to take on that desired jello-y texture.
Place silicone molds on top of a baking sheet for support. Then, spoon mixture into silicone molds.
Refrigerate for 1-2 hours, or until fully set.
