I also attended seminars along with professional trade shows and allowed mentoring by others who had more expertise.
During my early years I earned the nickname "Green Flake Man" at these trade shows for my research into fish food, in particular those with high amounts of Spirulina Algae.
Where this article differs from most all others is this information and research dates back several decades and ALL recommendations (& fish food developments) are based on this in depth research.
This is UNLIKE most articles that are written after so as to support the latest marketing scheme for a premium fish food.
This is not new to the hobby either, or even to fish foods, as I have been to pet nutrition seminars where it is pointed out that the ingredients are quality, but the optimization is lacking.
Often what is pointed out in fad foods is their fish are growing and doing well, but in reality these fish are simply going through their life cycle fast, similar to Beef Cattle fed grains and high growth formulas to get them to market fast versus Cattle fed a slower but healthier growth "grass-fed" diet.
For example; Cats need Taurine in there diet or they can suffer heart problems.
Back to fish; the wrong amino acids in any fish will lead to aquarium pollution (extra ammonia) from lack of digestibility and potential renal failure (kidney failure) in the fish.
Another point is amino acids (the building blocks of proteins); almost all animals have different amino acid needs.AAP All Natural Fish Food Hopefully this article can educate readers as to all important aspects of what goes into an optimum prepared fish food diet.This way readers can apply this information to any fish food in an educated manner.Regardless of whether the fish' diet is 100% prepared or prepared that is supplemented with live/frozen (which I have had test fish do very well in controlled tests on 100% prepared foods), you want to seek a fish food that has the lowest amount of supplementation as well as one that is optimized as per energy points, fiber, and proteins to make the food viable diet. Any prepared fish food that has to add vitamin, mineral, and other supplements to bring their food up to higher standards is obviously not providing these via optimal ingredients and/or is cooking them out via the preparation process (such as making flakes or pellets versus crumbles which destroys less of the nutrition value).Admittedly even some of the better brands perform supplementation, but I still would seek a fish food that supplements as little as possible.We also know from studies in human nutrition that certain diets add to inflammation and oxidative stress.
