Hikari Sinking Wafers Ingredients Analysis

Primary ingredient is fish meal. Being a Hikari produced fish meal; we can have confidence in the nutrient and protein levels of the meal. However, not being labeled as “Whole Fish Meal” identifies that the meal is potentially compiled from leftovers after the more desirable components of the fish are used for human consumption (pending clarification from Hikari).

The next preferred protein source listed is Dried Seaweed Meal, an excellent natural source of vitamins and minerals. Dried Seaweed Meal (aka Kelp Meal) qualifies as a preferred plant protein.

A total of eight non-preferred protein sources are listed compared to four preferred protein sources. With wheat split into multiple products and two of the preferred protein sources (Krill Meal and Spirulina) being listed too far down the ingredient list to provide significant nutritional benefit, the preferred protein content is questionable.

Dried Bakery Product is a mixture of surplus and unsalable materials collected from bakeries and other food processors. In other words, old stale bread, cakes, tortillas, pasta, cookies, candy,.etc… It is added to fish food as a source of protein and a flavor enhancer (sure give the fish a donut).

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.

Listed Vitamins and minerals are acceptable.

This food does not contain Ethoxyquin or artificial colors. However, it does contain Menadione Sodium Bisulfite (synthetic vitamin K).

Oscarfish.Com Rating: 3 Star

Questionable ratio of preferred protein content vs. fillers, binders, or non-preferred protein sources, combined with use of Menadione Sodium Bisulfite (synthetic vitamin K), prevent a higher rating. The known quality of Hikari fish meal, an absence of both Ethoxyquin and artificial colors, and significant use of a preferred plant protein (Dried Seaweed Meal) justify a 3 star rating.

Understanding Oscarfish.Com Ratings:

This review is an attempt to analyze the ingredients, rating them from 1 (worst) to 6 (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
