RotiGrow

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.

RotiGrow® Grow-Out Feeds

These base feeds are carefully formulated to produce healthy and vigorous rotifers despite high-density, stressful conditions. These feeds are the first step in building HUFA lipid membranes, gut-loading, and achieving optimal nutritional profiles, while limiting harmful bacteria.

N-Rich® Secondary Enrichment Feeds

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.

RotiGreen® Greenwater Feeds

Our Rotigreen® Greenwater Feeds are rich in DHA, EPA and ARA maintain optimum rotifer enrichment in the larval tank, and provide optimum nutrition for gill-feeding larval fish. With excellent suspension in the water column, they help jump-start the digestion of larvae, and reduce “nose bumping” and associated disease. See all of our Greenwater Microalgae Feeds.
