Optimal vitamin, lipid and carotenoid enrichment results are achieved from the right combination of base feed, enrichment feed, and duration of enrichment through the use of our proven protocols. N-Rich products increase the HUFA levels of the rotifer to match the nutritional requirements of the fish without stressing the rotifers. N-Rich products are exceptionally clean, effective and easy to use. With natural carotenoids (including astaxanthin) and vitamins, N-Rich products provide broad-spectrum rotifer tissue enrichment, health and nutritional maintenance during cold and warm storage and gut loading.
