OSI Freshwater Flake Food Ingredients Analysis

The primary ingredient is fish meal. We have no way of measuring the quality and nutritional value of the meal being used as the source is unknown. As a result, the quality and subsequent nutritional values are questionable. Use of fish meal, instead of the “whole fish meal” indicates the primary ingredients are potentially fish processing left overs (scales, skin, bones, internal organs) deemed unsuitable for human consumption.

As the third listed ingredient, Algae Meal is a preferred plant protein that provides a natural source of vitamins and minerals, although Spirulina Meal would be preferred.

As a general statement, shrimp meal is a lower quality protein source than is fish meal.

There are three preferred proteins listed in the first 5 ingredients vs. two non-preferred protein choices. Despite concerns about the nutrient levels of the fish meals, there is marginal confidence the primary protein source of this food comes from preferred proteins.

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 content.

This flake food contains each of the three least desired ingredients in fish food. Ethoxyquin, “artificial colors”, and Menadione Sodium Bisulfite Complex (synthetic vitamin K. )

Oscarfish.Com Rating: 2 Star

Based upon preferred protein content alone, this food would justify a 3 star rating. Quality questionability of the fish meal in use, preferred protein to filler, binder, and non preferred protein ratio, combined with inclusion of Ethoxyquin, Menadione Sodium Bisulfite, and artificial colors prevents it from being rated higher.

Understanding Oscarfish.Com Ratings:

This review is an attempt to analyze the ingredients 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
