N-Rich® Products

Instant Algae® RotiGrow® Products — the Most Convenient and Effective for Growth, Enrichment and Greenwater Productivity

Your hatchery has a unique set of needs. That’s why Reed Mariculture devotes countless hours to the optimized formulation and rigorous testing of the highest quality feeds that mimic feeds found in nature. Our unique Instant Algae concentrates and custom blends are being used successfully by over 500 hatcheries, universities and marine ornamental operations in more than 80 countries.

In contrast to traditional practice, we produce only whole-cell, whole food microalgae feeds and enrichment products from marine algae using proprietary processes. Maximum rotifer nutrition is achieved because all biomass is from microalgae. Intact whole cells ensure that rotifers receive the maximum nutritional benefit from our exceptional feeds, which in turn provides maximum nourishment to your fish. Our feeds also produce clean rotifers that ordinarily do not require washing, so they can be pumped directly into the larval fish tank.

We offer a complete system of products that work together to support optimum grow-out, enrichment, gut-loading, and productivity.

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.

Pav DHA

Pav DHA is the predecessor to our N-Rich products. It is a blend of Pavlova and other microalgae created to achieve a high level of nutrition for rotifers before they become nourishment for larval fish. Rotifers are nutrition-delivery devices. Their nutritional value comes from both enriched rotifer tissue and the feed loaded into the rotifer's gut. Soft tissue and gut contents are squeezed out of the rotifer by the larval fish when the rotifer is consumed and the rotifer lorica and eggs often pass undigested. So it is important to sensure that the gut and soft tissue offer the highest nutritional value. LEARN MORE
