Nutra-Kol products

Arti-Kol is a tailor-made Artemia enrichment that can be designed to suit any nutritional and/or experimental requirements. Today, there is large variety of commercially available enrichments with different levels and ratios of essentail fatty acids, anti-bacterial agents, vitamins etc. However, in some cases, especially with new species or susceptible larvae, different levels and/or other ingredients are needed in the enrichments. For example, immune-stimulants and mega doses of vitamins E and C are used to increase stress resistance and reduce deformities. In public aquaria and ornamental fish hatcheries, stress resistance and coloration enhancement is needed. These can be achieved with high levels of carotenoids.

Live food (rotifers and Artemia) is considered to be a vector for bacterial infections in marine larvae, resulting in reduced growth and survival. During the hatching and enriching process, bacterial numbers increase by 5-8 fold. These bacterial populations remain well established and are very hard to remove from within the nauplii by rinsing with freshwater.

NutraMicro fish larvae weaning diet based on cold extrusion method which results in a semi-moist weaning diet. Due to its physical and chemical properties, NutraMicro is easy to digest by the larvae. NutraMicro weaning diet can be tailored to any species requirements even in small batches. NutraMicro particle size ranges between 200-800 microns.

The metamorphosis stage in fish larvae marks the transition to the definitive phenotype of all the body systems, such as; digestive system, visual and olfactory, skeleton, muscles, skin, pigmentation and behaviour. This transformation process from embryo to fully developed fish demands high physiological and nutritional resources from the larvae. Therefore, if larvae arrive at this stage in a condition that is not optimal, its chances of survival deteriorate significantly.
