RotiGrow® Nanno (Nannochloropsis)

Highest Yielding Grow-Out Feed

RotiGrow Nanno is our highest yielding rotifer feed. It is single-species (Nannochloropsis) and produces phospholipid-rich rotifers. It also provides the highest Feed Conversion Rate of our products, with the least organic waste in the tank, and gives a high EPA and ARA pre-enrichment boost for use with high DHA-enrichment protocols. Strain: CCMP525

Photomicrograph of RotiGrow Nanno

RotiGrow Nanno Offers:

  • Healthy Rotifer Cultures — Rapid growth, minimal fouling and reduced bacteria loads
  • Highest Yields — Rotifers can double daily at densities over 8,000 L-Type rotifers per ml
  • Optimum Enrichment — Supports full highly-unsaturated fatty acid (HUFA) enrichment; the best source of EPA and ARA as well as critical vitamins
  • Concentrated, Clean, Liquid Form — Exceptionally clean and easy to use with minimal foaming or clumping, which means less time spent maintaining cultures
  • Long shelf life — frozen, three years

The RotiGrow System *

A two-step rotifer feed and enrichment system employing two supplemental feeds that further enhance larval fish nutrition. All our feeds are produced using proprietary processes with 100 percent of the biomass composed of nutritionally rich blends of microalgae. All feeds contain 75 – 95 percent intact whole cells for whole-food, whole life-cycle support.

STEP 1: RotiGrow Nanno

Highest Yielding Grow-out Feed
Supports Pre-Enrichment and Highest Yields

RotiGrow Nanno, a single-species (Nannochloropsis) feed, provides the highest Feed Conversion Rate of our products, with the least organic waste in the tank, and gives a high EPA and ARA pre-enrichment boost for use with high DHA-enrichment protocols.

STEP 2: N-Rich

One to Eight Hour Secondary Enrichment (with blends to meet the needs of your species of fish)
Full HUFA and vitamin enrichment plus "Whole-Cell" Nutrition

N-Rich offers a unique blend of microalgae that provides a wide spectrum of essential nutrients, including high levels of protein, carotenoids, sterols and optimized vitamin C, A, D and B vitamins. N-Rich can raise the nutritional profile of enriched rotifers to meet the needs of any fish.

Additional Products for Nutrition Enhancements:

STEP 3 (OPTIONAL): Cold storage and/or Gut Loading with N-Rich or Isochrysis/Pavlova Blend

Digestive and "Whole-Cell" Nutritional Support for Larval Fish

N-Rich High PRO is a nutritionally balanced rotifer finishing feed that is easily digested when released into fish larval guts. It contains a blend of microalgae including Pavlova and Isochrysis. N-Rich High PRO offers an optimal fatty acid profile, plus carotenoids, sterols and the right amounts of vitamins A, D, C, and B's.

STEP 4: RotiGreen

Greenwater: Isochrysis, Nannochloropsis and DHA/EPA blends Greenwater to Promote Overall Fish Health

RotiGreen greenwater (RotiGreen Iso, RotiGreen Nanno and RotiGreen Omega) further supports rotifer and larval nutrition in the larval tank to promote health and enhance survival.
