Nutra-Kol products

NutraFeed maturation diet is specifically designed for crustaceans broodstock. The diet is semi-moist (up to 30% moist) and manufactured as short pellets at any length and diameter needed. The diet is stable in water for 24 hours and will not break down when the animal is holding and chewing it.

NutraBrood is a tailor-made feed additive designed to enhance the nutrition of marine fish (as well as other marine organisms such as crayfish and others) broodstock.

One of the problems with shrimp (and other crustacean) culture is broodstock diets and nutrition. Currently, most hatcheries around the world are using fresh or frozen squid, worms (polychaetes), fish and other marine organisms, topped up with nutritional additives. This practice is far from ideal, exposing the cultured animals to potential pathogens and diseases, nutritional inconsistency and is dependent on wild fisheries. Considering the cost of broodstock (especially SPF), these are serious risks and in many cases result in high mortality and/or reduced productivity, leading to significant financial loss. Until now, broodstock fed maturation formulated dry diet, pelleted or extruded did not match the performances of animals fed on fresh/frozen food. The dry diets tend to break down due to the unique feeding behaviour of the animals, resulting in polluted water and very high FCR. Moreover, palatability and ingestion rates are usually low.

Nutra-Brood is a tailor-made feed additive designed to enhance the nutrition of marine fish (as well as other marine organisms such as crayfish and others) broodstock. Nutra-Brood supplied as an oil emulsion that can be injected into the broodstock’s fresh food using a syringe. The basic feed additive contains essential fatty acids, vitamins, minerals, carotenoids and other essential nutrients.

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.
