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 NEO Index® has been developed to deal with all these factors in one.
JBL PROPOND STAPLE is an ideal all-season food for water temperatures between 10 and 25 °C. If the water temperatures fall below 10 °C, a special low-temperature food such as JBL PROPOND WINTER should be used. At water temperatures above 25 °C we recommend you change to a special "high temperature food" such as JBL PROPOND SUMMER.
