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.

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.
