catfish food for koi :-)
I think it comes down to what do the experts feed their koi, their dogs. People like
Brett Rowley who breed koi use high quality feed like Rangen, and he has to minimize his costs to stay in business ..... he got more koi mouths to feed than all of us put together. And Brett knows more about breeding and raising healthy koi than all of us put together. I am on a dog list as well, and the same issue comes up about cheap bulk dog food vs better brands. And part of my decision to feed high quality koi food is because I can actually see the difference between high protein dog food and the cheap stuff that is mostly fillers. When my two big springers take a dump after eating cheap food the pile is enormous. With high protein food there isnt 1/2 the wastes. The difference was obvious when I switched from cheap GF food to high protein. My filters stopped getting fouled with undigested food. Bulk is in one end and out the other. I think it is pretty clear all over the world what happens when people eat high starch diets. The majority of them get huge ... but it is obesity, not "sleekly fat" Minimize the protein and they are runted, never attaining their growth potential. Limit protein to children and they never develop full brain potential and their immune system is compromised. Those little kids with big bellies are the result of a lack of protein, but plenty of starch in their diet. I dont have high dollar koi, but they are my pets.. and they are worth a buck a year each to feed them high quality food. Fish are good converters of food, I think it is something like for every 2 lbs of food they put on 1 lb of weight. So fish just dont need so MUCH food. And since I want to maintain the highest quality water I want to use food that isnt going to unnecessarily make it more difficult. Ingrid "Just Me \"Koi\"" wrote: 1.

This is an incorrect statement. I am not now, nor have ever been in the business of
selling high priced koi or any other kind of food. Jo Ann is a friend that I can recommend for certain products. Most of the time when I recommend Jo Ann it is for people with sick fish to call her for help, which is free. I recommend AES or "that pet place" 95% of the time for fish related products. I pay for the food I buy from Jo Ann and I have the credit card slips to prove it. I have no financial arrangement of any kind with Jo Ann, I get no money or goods as the result of my recommendations from Jo Ann, from AES or from "that pet place". I, my list, my website do not get a SINGLE PENNY from any seller of any product at all.

catfish food for koi :-)
Jo Ann and Steve got 77 koi in their big pond. they range from 5-20 lbs each
Steve gives them 2 pints of food per night (which weighs 16 oz), combination of Ogata and Rangen. the RETAIL cost of feeding their monsters is: 6.5 cents per day per koi 45 cents per week per koi 23.63 bucks per year per koi cause they feed 365 days a year down there in Ala and they heat their ponds. The koi are monsters and are growing. their 5 lb fish are around 18-22", so it averages out maybe to around 0.25 lbs per inch for those big fish. a quick and dirty estimate of the average is they got 940 lbs of koi and feed 16 oz of food per day. I am not sure how many koi I got. Lets say 25 koi from 6-14", I know they arent 0.25 lbs per inch, but lets say my 25 fish weigh in at 40 lbs. I should be feeding 1/24th as much food as they do, or 2/3 of an ounce per day. Well, I think I feed more than that cause I been feeding a less than 1/2 cup or around 1.2 oz of food per day. Last year I bought 5 lbs of Rangen ($4/lb) $20.00 5 lbs of Ogata (5.50/lb) 27.50 5lbs of romet B ($4) 20.00 -------------------------------------------- 67.50 I had Ogata left this spring been using it and will run out this week. I have romet B left and I gave away at least half to people with sick fish. I started feeding around April 15 when the water is above 55oF. I quit feeding around Oct 8th. I didnt keep records on first and last feeding. But this was around 25 weeks I fed the koi. Lets say 24 weeks cause I forget to feed them every day. So 24 weeks X 7 days X 1.2 ounces per day = 201 ounces per year or 12.6 lbs. If I feed them according to Steve's rate, I should feed 110 ounces per year or 6.9 lbs of food. However, I feed 25 koi 12.6 lbs of food per year, average price is $5/lb or so comes out to $2.50 per koi. Feeding at Steve's rate 6.9 lbs x $5 = 34.50 or $1.38 per koi per year. It doesnt add up right, I have more food left over so I may have missed more feedings than I thought or not feed 1/2 cup. I dunno. Yeah, that comes out to about 1/2 lb per year per fish. High quality koi food is around $5 per lb. High quality koi food has more digestible nutrition per ounce so I dont have to feed as much and there is less waste coming out the other end to foul my water and foul my filters. Anybody wanna feed catfish food to save a few bucks no skin off my nose. I will feed my fish what Brett feeds his.

Ingrid, I hope you are sitting down, as this time you and I agree on a
topic! (I mean that in a positive way, not negative, just to clarify). Food quality does matter! Yes, any animal can survive, eating almost any non harmful foodstuff, regardless of its nutritional value. The animals will grow, mature and eventually die, just as others eating a different more balanced foodstuff. Size though can be deceiving. Just look what is happening in this country with obesity. It is a national epidemic. Medical studies have shown its not just lack of activity (esp. in children/young adults), nor is it just the amount of food consumed (total daily caloric intake) but it is related to the quality of our food. Fats in the diet don't lead to obesity anywhere near as much as some of the carbohydrates do! In mammals, fats are utilized primarily for energy. If there are not fatty calories available, then stored carbohydrates are utilized. Excess carbohydrates are stored as fat, once glycogen storage is maxed out. As most USA diets have excess calories, the excess is stored as adipose tissue (fat) for later use by the body when there is inadequate caloric intake to meet energy needs (which rarely occurs in the average US diets hence the obesity). Yes kids grow into adults, and they are big and seemingly healthy (like our fish), yet many are getting early cancers, heart disease, many have more and more immune related issues like asthma, chronic sinusitis, etc, etc, which we (the medical profession) finally have realized has a major dietary component to it, in addition to genetics. So how does this relate to fish? I am not an expert of fish food. I do know the percentages of components that should be in a good quality diet; the difference between the sources of lipids (fats), (with fish oil being preferred); the differences between digestibility of various heat stabilized vit C products; as well as understanding the facts behind the hype about color enhancement and immune stabilizing additions; etc, etc., but I am not a breeder/commercial grower, and have not had the experience some in this NG have. That being said, I have read quite a few articles on feeds available, and growth studies etc. None of them however, at least any of the ones I have seen, address long term health/longevity. At a wet lab Dr. Johnson stated, (and I think he probably has written this somewhere I am quite sure), that when evaluating the causes of "swollen belly" in Koi (vs. dropsy which has a whole different set of causes, and you usually call immediately tell the 2 apart as in dropsy the scales stand out away from the body) the most frequent cause of "swollen belly" he has seen is fatty liver, due to poor diet, specifically "due to feeding of catfish food to Koi". That is his quote and his opinion, based on his aquatic vet. practice for the last 12 years, not mine. It makes sense though, although granted it is anecdotal. BTW, The other causes of "swollen belly" are fecal/roe impaction, cystic kidney, tumor, abscess, etc. I'm not saying you need to buy $20 per pound fish food!! I am saying I would rather buy a few higher quality feeds, mix them for a varied diet (along with household veggies, etc), and feed less in total calories, than to feed more calories of a lesser quality food that has proteins, etc that may not be as efficiently utilized, which results in fatty deposition in the liver and in the belly. Size and speed/amount of growth are not necessarily synonymous with health and longevity. All that being said, I think are plenty of high quality foods available, with prices that vary. I would not recommend any one brand, as I have never seen a head to head comparison of foods reviewing their impact on the above factors (health (immunity issues), and longevity) Happy ponding, Greg "~ Windsong ~" wrote in message ...

Ditto, I'm with Ingrid & Greg and don't have anything more to add to the
discussion except, did you happen to see the Mallard Filmore Cartoon? **Goldfish in a bowl saying: "Apparently, America has an "overweight-pet" problem.... It doesn't affect me.... I'm on the "eat too much and they find you floating upside-down.... and flush you down the toilet" diet. ** That's a keeper for the frig, along with the summer of Zits cartoons when the 2 teen males decided they could make money digging koi ponds, course they had to first find out what a koi was, and why it needed a pond. ) ~ jan On Tue, 17 Jun 2003 02:48:58 GMT, "Gregory Young" wrote: Ingrid, I hope you are sitting down, as this time you and I agree on a topic!

The average age of wild carp live in those european rivers is brief indeed. There is
a difference between just getting enough and thriving. Everything I have read says koi need protein to build muscles and fat for energy. That they cannot digest complex carbohydrates. Koi teeth are not made for thorough mastication of foods, nor do they secrete digestive juices into their mouth while they chew. Our land based adaptations help us start pre-digesting our food so the nutrients can be extracted before the food mass exits our body. Koi dont have a true stomach, they have a pyloric ceca which contains digestive enzymes and their liver and pancreas secrete enzymes right into the intestines. Land based animals like us produce acids that start the breakdown complex and land based foods in the large stomach. Everything koi have evolved to eat is wet with little to no cellulose. They have evolved to be a perpetual eating machine. They eat small amounts of low fiber, nutrient rich foods all day long, not big chunks of dry food with lots of fiber/filler. Fiber does not help them digest out the protein and fats they need from the mass of food moving through their intestines in a large bolus. Koi are adapted to digesting simple fats, the kind that go rancid very fast if food is sitting around in a warehouse. But corn oil and vegetable oils are typically used in cheap fish farm foods because they are cheap and dont go rancid at room temp. Manufacturers of food for farmers that grow food fish (catfish) have found ways of pre-digesting the complex carbohydrates and fats so they are available to put size and bulk on catfish quickly. People do report fish fed on corn develop fatty livers. I dont know if this is directly related to the corn in the food, or the fact that the food could be rancid anyway and rancid oils will cause fatty liver disease. In any case, food fish are processed and in the stores before any problems show up. OTOH, Jo Ann, who routinely does necropsies on GF and koi says she has never found fatty deposits in fish fed on high protein, high fat diets.

Excuse me Ingrid,
Please, give us just one meaningful scientific reference that "supports" what you are touting. Please don't use the Canadian professor again who is a salmon and trout specialist and has never worked with Carp or KOI. Why do you insist on continuing to spout this drivel. Algae is made up of cellulose which also makes up the majority of Spirulina, and any other plant that carp eat whether it is aquatic or land based. Most catfish foods have the same ingredients including vitamins, minerals, etc as the food that you are always touting, in fact, Rangan makes catfish foods and the process is very similar. I have spoken to the president of the company. Dr. Werner Steffens, Dr. Roland Billard, and Dr. Robert Stickney and Dr. John Halver all say that KOI and carp should have 28 to 32% protein to maintain these fish. All of these men are Aquaculturists and fish nutritionist and I have mentioned this to you and any one else who wants to know what is the right thing to feed their fish over and over again and yet it doesn't seem to soak in. The SRAC also has reports out saying the same thing and still you refuse to do any real searching to find out the truth for yourself. One of these days, you will realize how wrong you have been, but I surely will not be hold my breath and waiting for it to happen.

What she is saying maybe true for wild Carp and Koi...

catfish food for koi :-)
First John,
There is no such thing as wild KOI. KOI are the domesticated variety. The only thing that she says about wild carp is that they have a brief life in the wild. She then goes into talking about protein needed by KOI; 'nough said. She is still wrong. This is getting laughable. Tom L.L. "john.stoddard" wrote in message news What she is saying maybe true for wild Carp and Koi... How many times have you been to a wild koi pond and found naturally occuring bags/boxes/containers of koi food. Diets of Wild and Captitive Fish should not be compared "Tom La Bron" wrote in message ... Excuse me Ingrid, Please, give us just one meaningful scientific reference that "supports" what you are touting. Please don't use the Canadian professor again who is a salmon and trout specialist and has never worked with Carp or KOI. Why do you insist on continuing to spout this drivel. Algae is made up of cellulose which also makes up the majority of Spirulina, and any other plant that carp eat whether it is aquatic or land based. Most catfish foods have the same ingredients including vitamins, minerals, etc as the food that you are always touting, in fact, Rangan makes catfish foods and the process is very similar. I have spoken to the president of the company. Dr. Werner Steffens, Dr. Roland Billard, and Dr. Robert Stickney and Dr. John Halver all say that KOI and carp should have 28 to 32% protein to maintain these fish. All of these men are Aquaculturists and fish nutritionist and I have mentioned this to you and any one else who wants to know what is the right thing to feed their fish over and over again and yet it doesn't seem to soak in. The SRAC also has reports out saying the same thing and still you refuse to do any real searching to find out the truth for yourself. One of these days, you will realize how wrong you have been, but I surely will not be hold my breath and waiting for it to happen. Tom L.L. -------------------------------------------------- wrote in message ... The average age of wild carp live in those european rivers is brief indeed. There is a difference between just getting enough and thriving. Everything I have read says koi need protein to build muscles and fat for energy. That they cannot digest complex carbohydrates. Koi teeth are not made for thorough mastication of foods, nor do they secrete digestive juices into their mouth while they chew. Our land based adaptations help us start pre-digesting our food so the nutrients can be extracted before the food mass exits our body. Koi dont have a true stomach, they have a pyloric ceca which contains digestive enzymes and their liver and pancreas secrete enzymes right into the intestines. Land based animals like us produce acids that start the breakdown complex and land based foods in the large stomach. Everything koi have evolved to eat is wet with little to no cellulose. They have evolved to be a perpetual eating machine. They eat small amounts of low fiber, nutrient rich foods all day long, not big chunks of dry food with lots of fiber/filler. Fiber does not help them digest out the protein and fats they need from the mass of food moving through their intestines in a large bolus. Koi are adapted to digesting simple fats, the kind that go rancid very fast if food is sitting around in a warehouse. But corn oil and vegetable oils are typically used in cheap fish farm foods because they are cheap and dont go rancid at room temp. Manufacturers of food for farmers that grow food fish (catfish) have found ways of pre-digesting the complex carbohydrates and fats so they are available to put size and bulk on catfish quickly. People do report fish fed on corn develop fatty livers. I dont know if this is directly related to the corn in the food, or the fact that the food could be rancid anyway and rancid oils will cause fatty liver disease. In any case, food fish are processed and in the stores before any problems show up.
