Assessing a Koi and Pond Fish Food Ingredients Label

Assessing an ingredients label

Ingredients labels can be very exciting, or very misleading.

They can be exciting because they seem to report excellent ingredients and real care and attention in manufacture. Misleading labels use techniques like ingredient splitting and foreign law to dupe the consumer. Come with me to the store and we shall assess a label together in nine steps.

Assessing the Fish Food Label: Step-By-Step

Assessment 1: Protein source.

Look for fishmeal, squid meal, whitefish meal, anchovy meal, shrimp meal, blood meal, herring meal, etc as first ingredients. These are the best protein sources for fish and are the ones I recommend. Other proteins, for example if you found a bag of food that showed Lobster meal as the first ingredient, you understand that again, aquaculture protein is best for aquaculture.

Assessment 2: Purpose of plant material

If you find a food that has NO animal protein, therefore no fish protein, AND it also has TWO plant proteins, then the manufacturer is trying to get cheaper plant ingredients to do what fishmeal should be doing. And Koi feeding results will be mediocre at best. However, if you find a food with FISH MEAL as the first ingredient and THEN wheat germ meal or similar, they are using the plant ingredient for protein AND energy, letting the fishmeal carry the bulk of the protein requirement, which is as it should be. There will be some plant protein in most foods. It’s used as a helper, dual-purpose ingredient and it’s not to be eschewed.

Assessment 3: Ingredient Splitting

Look for any ingredient TWICE on the list.

If you were manufacturing a food and found wheat to be cheaper than fishmeal, you would want to use wheat to save money. But, you know the consumers want the fishmeal to be FIRST on the list. So you split the wheat!

Example:

Two pounds of fishmeal is less than three pounds of “Wheat”. Right?

So, honestly, that would read:

Ingredient one by weight: Wheat

Ingredient two by weight: Fishmeal

But what if you did your label based on:

2 pounds Fishmeal

1.5 pounds Wheat “germ”

1.5 pounds wheat “flour”

I’ve split my wheat into two “separate” parts and they’re taken separately into the label and my Fishmeal is boosted to the TOP of the list.

Assessment 4: Protein percent.

Let’s say a company who is tailoring a feed to the prevailing market-climate wants to use FOUR aquacultural proteins, and tosses in shrimp, kelp, spirulina, and squid meal. That would be AWESOME! But it could jack up the proteins to a level unsuitable for fish, or at least unnecessary (and expensive). The protein level in a decent diet should be about 32-36% …Partly because Koi can’t digest more than that in one pass. I don’t know that feeding MORE than that is a “Bad Thing” because fish will simply pass what they don’t digest. So, looking for minimums, and recognizing that an outrageously high protein percentage you might be paying for is unnecessary, are the two take-away tidbits on this assessment.

Assessment 5: Fat content

Find a food between 3-10% Crude fat. Go to the higher end of my range for smaller fish, and closer to 3% for adult fish.

Assessment 6: Ascorbic acid

Make sure “ascorbic acid”, or “L-Ascorbyl-2-Phosphate” or similar is on the label among the trailing ingredients. It will represent a very small part of the diet but it should be added to any milled food.

Assessment 7: Immune boosters

Some foods are made with immune boosters. These are certainly harmless and they may very well perform as promised depending on what we’re talking about. Look for any combination of following putative immune-boosting ingredients like: Optimun, Aquagen, Nucleotides, Torula Yeast, Brewer’s Yeast, Bee Propolis, Colostrum, Aspergillus niger, beta carotene, lactoferrin. Don’t hang your hat on any particular ingredient as a miracle supplement or life saver – okay? …but recognize that the addition of these items represents the manufacturer as a little more attentive and knowledgeable, and the food worth a little extra money.

Assessment 8: Color enhancers

Are there color enhancers in the diet? Look for terms like Spirulina, Bio-Red, BetaCarotene, Canthaxanthin, Marigold petals, Xanthins, Shrimp Oil, Synthetic and Non Synthetic Carotenoids, Color Enhancers…On the label. Generally, the shrimp oil is the most expensive. It performs as well or better than the synthetic carotenoids but either is acceptable. Spirulina cannot push color unless the fish are exposed to sunlight. None of these color enhancers are hazardous to fish but can make a fish with a yellow head YELLOWER and so they say: a fish with a tendency towards pink pinker. No color enhancer can replace the irrefutable contribution of genetics and sunlight to color.

Assessment 9: Ash content if stated.

Sometimes companies will level with you and tell you the “crap” content of their food. Ash is what’s left behind when you incinerate (or the fish digests) the food. It’s almost all carbon and mineral. So the higher the ash number, the less likely one is to appreciate it. Generally, when Ash is high, a smart label guy would just leave it off, and they are allowed to because it’s not required on fish food bags.

This is The LCD Screen Scope
We Did The Tutorial With. I did a twenty page tutorial (Here's the tutorial) with video, audio, images and even little parasite movies to show you how to use a microscope. 

This Filter is Good For BIG Dirty Tanks
I've been wrestling with water quality with the turtles. The sponges work GREAT, but in THOSE turtle systems where they eat MICE the poops are bulky. This filter can handle it. In "Tortu's" tank, it's got an 800 gph pump and it rocks. 

PraziPro for Flukes
They nailed it. Figured out the solubility and worked out the dosing. It works. 

Buy Some Good Koi?
No, this isn't really for the 'high end' collector y'all. But for someone who isn't near a decent garden center, here are "good-to-quite-good" Koi you will like at a very good price. I know these guys personally.

Best Food, Ever
It's made for (and I discovered it for) my Blood Parrots but the small size, intense color enhancers and excellent formulation make it superb young-Koi food. Oh, and it's AMAZING on color-cichlids like Flowerhorn and Blood Parrots. 

Pro Air 60 Aerator is a VERY high output air pump pushing my whole fish room (17+ drops), and I have one at home driving everything there, and I have one as a back up. 

Formalin Malachite (Not dilute)
There are formalin malachite preparations at 10%, 22% and 37%. There's economy in the concentrates. Hard to get Prime shipping because air transport is curtailed. This is a good value on 32 ounces. 

Topical For Koi and Pond Fish Ulcers
I like 7% tincture of iodine because it stains but it's hard to hurt anything with it. Used with a WOVEN gauze, this works well to clean and disinfect a wound. Only use ONCE. Do not 'repeatedly' scrub wounds. 

Confectioner's Glaze 
Is the way to bind a medication to fish food. Gone are the days of paste food and oil. The write up is done, it's RIGHT HERE.

Koi Health & Disease
Hopefully this link takes you to the newest edition by PRIME to get it to your house the fastest. 

I have over ten of these Titanium Heaters in my fish room and at home. They're a paradigm shift in aquarium heating. They're titanium and 400W for under $30! Whaaaaaaaaat?

CyroPro by Hikari is safe and easy for Anchor Worms and Fish Lice.

Whatever heaters you use, back yourself up with a temperature controller, it'll turn on, and off your heaters. If your heater seizes "on" at least the thermostat will stop a tragedy. 

LifeGuard by Tetra is a tablet version of a tame 'chloramine-t' or 'halamid' compound that's easy to get and good on bacterial infections, in baths. 

Antimicrobial
If you're making medicated feed for a larger group of fish, this will come in handy. Dosing is available in the site. 

For me, filtration-of-choice
For aquariums, even small Koi holding facilities or small ponds. These sponge filters are cheap, easy to clean, and they clear hazes very well when used with some Accuclear or similar.

Rubber sided, round, nettable tanks
Make great hospital or quarantine facilities. They SHOULD cost about $200-300 depending on size, but this, lower quality unit (while panned in some reviews) may be good. Don't overfill and make sure it's propped up.

1200 Watt heater, on a thermostat held securely above the waterline, works GREAT as a large tank heater. That's all I'll say because there's risk of electrocution and all that. But then, even in a bucket you could get killed. Sound like fun?
I have several of these ALLIED PRECISION stainless ones that are a couple years old. Working still. 

Potassium Permanganate 
500 grams could be a lifetime supply but it's 50% more than the 100g cost wise, for 500% more amount. Dosing is in the site and the book.

What Does Ajax Eat?
I looked for something well formulated, with meat as the first ingredient. Something UNDER $2/lb and something they could deliver for free. And this was it. He looks and feels great on it.
