ProPond® / NEO Index®


Feed your animals throughout the year with the natural, balanced JBL ProPond fish food, to keep them healthy and active for the long-term. All ProPond products from the seasonal food concept range contain high-quality ingredients in accordance with the NEO Index®. This species-appropriate nutrition provides the ideal amount of high-grade proteins and fats for the well-being of your animals at any temperature. By supporting all their vital functions it ensures active, disease-resistant fish with vibrant colours. The food is highly digestible thanks to its prebiotic ingredients. In addition to the Season Food, JBL ProPond offers you other dedicated foods which can be used to meet specific requirements, either as a complete food or as a supplement.


In May 2016 the only physiological-nutritional concept with the NEO Index® was introduced to a broad professional audience at the Interzoo in Nuremberg (Germany), the globally leading trade show for the world of pets. Scientists and pond fish experts first developed the food concept and then they built a production line especially for the product and housed it in its own dedicated building! This is a huge step towards species-appropriate animal care and towards animal welfare in practice. And we are as pleased about that as you are! On this site you will regularly find new information and background data about nutrition and the ProPond foods until the sales launch starts in spring 2017. Just subscribe to our newsletter and you won’t miss any news or nutrition tips from our scientists.


NEO Index® literally means: natural, energy-optimised nutrition. Behind this lies the ratio of proteins to fats in the food. Looking at the season alone, the fish would only need half as much protein in winter (2:1) as in summer (4:1). But because not only the season (which means water temperature), but also the size and age of the fish, and food function (e.g. growth food) play determining roles, the der NEO Index® has been developed to deal with all these factors in one.

Anyone getting to grips with the subject of nutrition (also for us humans), will soon discover that proteins and fats are not all the same! This doesn’t only apply to our diet but also for the fish diet. The best model for high-quality food is the food spectrum of animals in the wild, because the animals’ organisms have been adapting and evolving for generations. All over the world scientists have been testing other natural food components for decades. These findings too have influenced the composition of JBL ProPond.



Proteins are basic components of the body and necessary for the building and renewal of body cells. Proteins as enzymes and hormones are also responsible for a wide range of tasks in the body. Amino acids are also classified as proteins and they create important conditions for healthy and good growth. Proteins can be found in all raw materials. Particularly suitable for the pond fish are protein sources from fish, crustaceans and molluscs.



Fats provide an important energy storage in the body and are therefore an especially important food component when higher storage is required (before winter). In addition there are also essential substances in fats (which the body cannot produce and have to be taken via food). High-quality fats with many Omega-3 and Omega-6 fatty acids are therefore an important supplement in fish food. Fish oil especially provides quite naturally the ideal composition of fats for our pond fish and further important substances, such as carotenes which support the colouring of the fish.



Just like us, our fish need an indigestible proportion of their diet to support the digestion. The crude fibres make sure that the food is better absorbed.



In crude ash substances can be found which can be absorbed as minerals or trace elements and are essential for many processes in the body. Important for the formation of the skeleton are, for example, calcium and phosphorus, for the metabolic processes sodium, potassium, magnesium, calcium and chlorine, and iron for the function of oxygen transport.


For our JBL ProPond pond fish food we set the highest quality requirements for the foods’ ingredients. Every single component is examined in accordance with our specific JBL quality criteria before the ingredient is used for the food. Especially important for us are the controlled cultivation, the freshness and the pollution control.


Even if your pond fish are always hungry and greedily eat any food they can get it’s important to get to grips with the subject of correct nutrition. It is not enough to select a food which is appropriate to the season. Proper nutrition needs to provide energy at the right time and in the right place.

Fish are cold-blooded animals! Therefore their metabolism always depends on the ambient temperature (water temperature). While the feeding needs to be stopped in cold temperatures during winter (below 5 degree Celsius) the fish need more and more food as the temperature increases.Even if the metabolism of the fish is dependent on the ambient temperature, a classification into metabolic rate, which is required for the maintenance of the life functions, and the active metabolic rate can still be made. These types of energy are dependent on the ambient temperature, age, sex and the activity of the fish.

From spring 2017 for the first time ever along with the JBL ProPond food range, you’ll be able to access over 100 articles created according to the NEO Index® on the basis of the criteria season, function, animal size and age.



Feeding with JBL ProPond, the only fish food range with the NEO Index®, means systematic feeding. Adapted to the optimal metabolism of your fish, JBL ProPond provides a wide choice either as a complete food or can also be combined with each other. Therefore the JBL ProPond range is divided into the 4 depicted elementary fields Season Food, Function Food, Special Food und Goody Food.


Proteins are basic components of the body and necessary for the building and renewal of body cells. Proteins as enzymes and hormones are also responsible for a wide range of tasks in the body. Amino acids are also classified as proteins and they create important conditions for healthy and good growth. Proteins can be found in all raw materials. Particularly suitable for the pond fish are protein sources from fish, crustaceans and molluscs.


The fish’s living conditions are also incorporated into the NEO Index® and factored in the different function foods. Thus the prebiotic ingredients of the fitness food provide ideal conditions for good health, even when the temperatures are varying wildly in times of seasonal change! The protein/fat ratio of 5:1 in the food helps your fish to compensate for their high metabolism without drawing on their energy reserves. This way they have enough energy to fight diseases and other issues. Function food is best when you are aiming to achieve certain ends: Your young koi also will grow without growth food, but they will grow more slowly and their body will not develop the beautiful shape it does when using this food. A colour enhancing food will bring out the colours of your fish and also make sure that the fish retain their beautiful colours after purchase. Retailers generally feed this food to show off their fish in their most beautiful colours. It will also help younger fish (mostly two years old) to develop their colours properly when they are 3-5 years old. If you regularly feed your fish with colour enhancing food their colours will show up more intensely, even at an older age


Along with size, age, season and water temperature the fish species also plays an important role, of course. Koi and goldfish are physiologically-nutritionally very close. That’s why goldfish can be perfectly fed with koi food during their whole life. Koi have a higher demand on the food since they often need to develop more and brighter colours. Sturgeons are very special fish. Their body shape indicates their way of life: They swim near the ground and use their barbels (chemosensor organ) to feel for small invertebrates, which they would eat in the wild. JBL ProPond Sterlet has been adapted to suit these eating habits, both in its composition (increased share of invertebrates) and in its sinking behaviour. Even if sturgeons can learn to feed at the water surface, this feeding behaviour doesn’t represent their natural behaviour and harbours the risk of excessive air swallowing. Sturgeons should always be fed with their own food because it has a dedicated composition and the sturgeons could hurt the koi’s mucous membrane with their bone plates when fighting for their food. In practice you can feed your goldfish and koi on the surface at a corner of the pond and your sturgeons with sinking sturgeon food at the other corner.


Even in the wild fish get goodies. Sometimes a fruit falls into the water, sometimes an insect lands on the water surface. With JBL ProPond goodies you can treat your fish to a special meal, which also offers another advantage. Your fish learn quite easily to eat out of your hand. Should you once need to catch a specific fish for an examination or treatment, you’ll be able to do this simply and easily thanks to the hand feeding. The ingredients of the JBL ProPond Goodies have been complemented so that these foods also can be fed as complete feed (which you couldn’t do with pure silkworm or shrimp food).


An optimal metabolism also needs to take the animal size/ age and the food size ratio into account. That’s why JBL ProPond provides you with 4 food sizes XS, S, M and L.

Naturally, along with size, age, season and water temperature the fish species also plays an important role. Do they feel for the food on the ground or do they feed directly at the water surface? Each ProPond food has therefore been adapted in its composition and its sinking behaviour to the different species and their eating habits.
