API Tropical Greens Ingredients Analysis

The primary ingredient is Condensed Fish Protein Digest, which appears to be a lower quality product than fish meal. It can better be defined as fish protein hydrolysate, which is the processing of what's left after the processing of fish meal. API is the only fish food manufacturer using it to this extent. More research is warranted.

Pea protein is a highly digestible plant protein known for its amino acid content (Lysine, Arginine, Glutamine, and Leucine). Its use in fish food is novel but welcome. There is ample confidence that primary proteins in this food originate from preferred protein sources.

While Shrimp Meal is a preferred aquatic meat protein, it is generally of lesser quality than are fish meals while Dried Seaweed meal is certainly a preferred ingredient, naturally introducing vitamins (including natural vitamin K) and minerals.

Beet Pulp is added primarily as source of fiber and to serve the role as filler. Of concern is the potential for it to swell in the stomach, causing blockage. There are arguments both for and against its use.

Dried Seaweed Meal is good source of iodine for thyroid function, chlorophyll,  Dietary Fiber, Vitamin C, Pantothenic Acid, Zinc, Copper, Riboflavin, Folate, Calcium, Iron, Magnesium, Manganese, and Vitamin K1.

Fish oil can be either a beneficial ingredient or a hazardous one. Human grade fish oil collected from specific specifies of fish and screened for mercury will provide necessary omega 3 and omega 6 fatty acids as well as protein. Non-human grade fish oil may not be screened for mercury and originate from fish with reduced omega 3/6 content.

Beet powder is a rich source of natural sugar that provides sodium, potassium, phosphorus, chlorine, iodine, iron and various important vitamins. In humans, it is considered a health food. It is likely added here more to impart red color in the flake. It is an undesired ingredient in dog foods.

Brewers dried yeast is a by-product of the beer making process, this ingredient contains about 45% protein and is rich in Vitamin B. Is use in fish foods is as either as a protein source or a vitamin supplement. Studies do exist indentifying its capacity to improve fish growth rates. When used as a supplement comprising between 2% and 4% of the food, this is an acceptable product. When used as a primary provider of protein comprising 25% or more of the food it is less acceptable as protein digestibility concerns have been documented. Its use in this food does not appear excessive.

Spirulina and Honey are listed too far down in the ingredient list to provide significant nutritional benefit. The additional inclusions of garlic powder, Carrot Powder, Dried Tomato Pomace, and spinach powder are appreciated.

This pellet contains BHT as a preservative, a known carcinogen banned in Japan, Romania, Sweden and Australia with adverse effects on liver and kidney functions. It not does appear to contain Menadione Sodium Bisulfite (synthetic vitamin K) or artificial colors.

Oscarfish.Com Rating: 3 Star

This flake food is a novel approach. At issue is the mix of quality ingredients with less desired ingredients. Use of pea protein and such a wide spread of aquatic animal proteins and preferred plant proteins, combined with an eclectic list of supplements such as Carrot Meal, honey, and spinach powder justify a 3 star rating, at least. Its use of BHT as a preservative, limited information pertaining to the primary ingredient (condensed fish protein digest), and over use of fillers and binders, that prevents rating any higher.

Understanding Oscarfish.Com Ratings:

This review is an attempt to analyze the ingredients, rating them from 1 star (worse) to 6 star (best), in an effort to judge quality based upon three simple criteria. 

  1. Absence of toxic, potentially toxic, and controversial ingredients
  2. Aquatic Animal protein and Preferred Plant Proteins as the primary protein sources
  3. A fully nutritious food to include necessary vitamins and minerals with natural sources of vitamins and minerals being preferred.

These basic concepts apply:

  • Any food that utilizes Ethoxyquin, BHA, or BHT as preservatives, cannot rate higher than a 4 star food.
  • Use of artificial colors prevents rating higher than a 4 star food.
  • Any food that utilizes Menadione Sodium Bisulfite (Synthetic Vitamin K, aka K3) cannot rate higher than a 5 star food.
  • Inclusion of the “Whole Fish”, or “Whole Krill” (in meal form or not) is preferred over fish meal or krill meal.
  • In order to achieve a 5 or 6 star rating, the quality of the meal must be known.
  • In order to achieve a 6 star rating, the “Whole Fish’ (or whole animal) must be used, either in meal form or in sufficient quantities outside of meal form.
  • Inclusion of sufficient quantities of preferred plant proteins is a bonus with sufficient Spirulina content being a significant bonus.
  • Use of prebiotics or probiotics is a bonus
