This is a recipe that a ranchu breeder I have gotten fish from uses. It has been around for a while and has appeared in the GFSA Goldfish Report. Mr. Kroshinsky seems to have success with this recipe, though he also feeds other things to his fish (notably prepared pelleted foods). This is essentially the "staple diet", which is then supplemented by other items for variety.
|Kroshinsky Gelatin Food Recipe|
|3||Large Red Bell Peppers|
|2 to 3||12 oz. pkg||Frozen Chopped Spinach|
|16||oz.||Plain Wheat Germ|
|32||envelopes||Plain Powdered Gelatin|
Liquefy first 4 ingredients in a blender, adding sufficient water for blender operation. Place in large pot, add wheat germ, and heat until warm stirring continuously. When warm, add the gelatin gradually, stirring continuously to avoid lumps. Stir in vitamin powder, then cool and refrigerate. Once solid and rubbery, cut into 3/16th inch thick sheets and freeze.
Defrost sheets as needed, cutting into 1/4th inch cubes prior to feeding.
Makes about 2 gallons.
Using the USDA Nutrient Database for Standard Reference (NDSR release 10), I did a nutritional analysis of this recipe for the major nutrients; these results are in the table below. The mass figures are all for a 100 gram sample; i.e. 100g of spinach has 2.9g of protein. "MUFA" and "PUFA" are mono- and polyunsaturated fatty acids, respectively. "Ratio" is the number of 100g measures of that food in the recipe: this is used as a multiplier for the 100g values, to get to the actual percentages in the food. Note that the info for water is just for that naturally occurring in the food. The added water in the recipe is not included.
|Food||Ratio||Water (%)||KCal||Protein (g)||Fat (g)||Carb (g)||T Fiber (g)||Ash (g)||Ca (mg)||P (mg)||Fe (mg)||Na (mg)||K (mg)||Vit A (IU)||Vit B1 (mg)||Vit B2 (mg)||Niacin (mg)||Vit C (mg)||Sat Fat (g)||MUFA (g)||PUFA (g)||Chol (mg)|
|total in 100g of mix||40.256||71.82||109.84||13.92||1.95||10.16||3.40||1.37||52.80||211.39||2.13||64.75||313.96||3113.06||0.27||0.18||1.47||42.66||0.34||0.33||1.04||16.03|
|total % in dry mix||49%||7%||36%||12%||5%||0%||1%||0%||0%||1%||0%||0%||0%||0%||1%||1%||4%||0%|
I would say this is a little high in protein for mature fish. For fish in a pond that get a lot of supplementary vegetable material it would be excellent, ensuring that they get sufficient protein.
