Nutrakol has manufactured several unique nutritional products aimed specifically at marine organisms cultured in intensive and/or extensive conditions. Nutrakol’s holistic approach in developing these products takes into account the organisms specific nutritional requirements, environmental conditions, stage of development (i.e. broodstock, larvae, juveniles) and many other conditions related to the development of an aquatic organism. Some of the products are ‘tailor-made’ to requirements while others present a viable alternative to the use of fresh and frozen feeds, reducing the risk of diseases and increase the stress resistance of any aquatic organism. > NutraFeed > NutraBrood > ArtiKol > NutraMicro > LobGrow Download our Nutrakol product brochure PDF.

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
