Vitamine C


Young Nishikigoi (Fry) do not only need vitamins to stay healthy, but also for the growth and the healing ability of the body. Further more vitamins are of great importance for the production of enzymes. Enzymes play a part in the metabolism of the body. Without enzymes there is no metabolism and food can not be digested and diverted to energy. Should you breed your Fry (f.e. in a quarantine facility) it is wise to add extra vitamine C.
Adult Nishikigoi obtain enough vitamine C from their daily feed and if necessary they can transfer glucose to vitamins. A supplement is therefore unnecessary.

There are two kinds of vitamins: watersoluble and acidsoluble vitamins. Acissoluble vitamins are mainly obtained from fat foods an can be stored in the bodycells. Watersoluble vitamins, that are mainly in the moist of foods can not be stored and therefore need to be replenished daily. Vitamine C is a watersoluble vitamin. Vitamine C is one of the most importand micronutrients. Not only is it a strong anti-oxydant (protection of tissues) but it is also very important for the metabolism and for the removal of toxics from the koi body. Vitamine is also essential for the build up of collagene, important for skin and the renewal of tissues and skeleton. It increases the intake of iron and fortifies the immunesystem. Further more vitamine C has an essential part in the maintaining and improving of the resistance against infections and inflammations.

Royal Jelly

Productfotografie, House of Kata, Gerrit Arends.

Royal jelly, which is secreted from the salivary glands of worker bees, serves as food for all young larvae and as the only food for larvae that will develop into queen bees. Royal jelly is harvested from the queens cells if the royal larvae are 2 to 3 days old. Per cell 110 to 210 mg jelly can be harvested. The production of royal jelly means intensive breeding of dam bees. In the first days all larvae are given the same food. After a few days the larvae that are meant to be worker bees are given a lesser quality food, but the future queens will continuously be fed with the royal jelly. A worker bee will live approximately 6 weeks, while the queen of the hive will live up to four years! A queen will grow 50 per cent larger than the worker bees and she will also mature faster. This indicates the power of royal jelly.


Usage: Use on our fish and Nishikigoi. Because of the composition royal jelly is a very valuable product. Royal jelly enhances the resistance against diseases and speeds up recovery. When used on fish and Nishikigoi you may also consider it as a stress relieving product. Ideally to be mixed with pellets or paste.
