Web Summary

Live food enrichments play an important role in delivering nutrients to marine fish larvae. Today, there are many enrichment products with different levels and ratios of EFA, anti-bacterial agents and vitamins. Species-specific enrichments are, however, lacking. Sometimes, especially with new species, it is desirable to have a product with a targeted nutritional profile. The author’s laboratory has developed two products that are customizable for either research or commercial applications in fish larval nutrition:

Nutra-Brood^® is a tailor-made feed additive designed to enhance the nutrition of fish broodstock. The product comes as liquid-oil emulsion that contains essential fatty acids, vitamins, minerals and other essential nutrients. It can be injected into the fresh food and is digested and absorbed in the fish gut.

Arti-Kol^® is a tailor-made enrichment product that can be designed to suit any nutritional and/or experimental requirements. For example, different levels and ratios of EFA, vitamins, therapeutics immune-stimulants, carotenoids and probiotics can be included. Specific nutrients and/or ingredients are incorporated into the oil/water matrix of the globules (liposomes) which is easily incorporated into live food.

The article discusses recent developments in fish larval nutrition research that were possible because of the use of above products.
