I can explain some more about their feeding... (the photo camera is too old

).
So, ingredients: shrimps bodies (~10-15 shrimps) + 1 middle carrot + 3-4 kalmar slices + a small part of white-meat fish (i.e.pike-perch).
1 white egg, 1/2 cap of milk, flour from algae. And you need in gelatin 7-10 g in this recipe.
To prepare: You need to prepare a 7-10g (may be more - read an instruction. 70-80g gelatin on 1 litre of mix) of gelatin. Carrot - boiled, covered, over low heat for 5 minutes and removed. Next bring to the boil and add the part of fish (do not add the salt.) for 20 minutes. Put through the blender together: shrimps, carrot, kalmar and fish (+chiken). Mix all and sautee stirring constantly to ~30-40°C. Add the 1 egg, 1/2 cap of milk and algae flour (polivitamins). When this mix and gelatin will be the same temperature just add gelatin into the mix - stirring again and pour into molds. Put in the freezer. It can be fresh about 3-5 days (always check it).
