Protocols for enrichment using Instant Algae products N-Rich with RotiGrow Plus, RotiGrow Nanno, and RotiGrow Chlorella

General Information

N-Rich feeds are exceptionally clean, effective and easy to use rotifer enrichment feeds that offers full fatty acid enrichment without stressing your rotifers. N-Rich is so clean that rinsing of rotifers after enrichment is unnecessary. N-Rich is an algal blend composed primarily of Pavlova and Isochrysis.

With Whole Cell-Whole Food microalgal nutrition, Astaxanthin and Stay-C added, N-Rich products provide broad spectrum rotifer nutrition for rotifer tissue enrichment, cold and warm storage nutrition maintenance and gut loading nutrition.

All N-Rich biomass is from marine microalgae (except Stay-C).

The N-Rich Family of Enrichment Feeds includes:

(Please see Table 7.1 and Charts 7.1b for enrichment feed comparisons)

  • N-Rich Extend – has very high protein content and appropriate levels of lipids and carbohydrates for optimal rotifer and larval fish health. Extend is used for:
    1. Extended enrichment (all day enrichment or overnight enrichment) with RotiGrow Plus as the base feed. Extend provides superior rotifer tissue enrichment with optimum DHA:EPA:ARA ratios and Lipid Class profile.
    2. Extend is used for two-stage extended enrichment with N-Rich Plus and N-Rich Nanno.
    3. N-Rich Extend is also ideal as a maintenance and gut-load feed for warm and cold stored rotifers. N-Rich is high in protein for long healthy rotifers and larval fish. Extend maintains rotifer health through proper protein nutrition.
  • N-Rich Plus – Used for rapid, yet gentle full DHA:EPA:ARA/Lipid Class enrichment in two hours or less. N-Rich Plus is formulated for use with RotiGrow Plus as the based feed and pre-enrichment. N-Rich Plus has a higher lipid content than N-Rich Extend, yet contains substantial levels of protein and carbohydrates for optimal rotifer and larval fish health.
  • N-Rich Nanno – Used for rapid, yet gentle full DHA:EPA:ARA/Lipid Class enrichment in three hours or less. N-Rich Plus is formulated for use with RotiGrow Nanno and Nanno 3600 as the based feed and pre-enrichment. N-Rich Nanno has a higher lipid content than N-Rich Extend, yet contains substantial levels of protein and carbohydrates for optimal rotifer and larval fish health.
  • N-Rich Specialty blends – Custom blend for custom application. Reed Mariculture is happy to custom blend enrichment formulas to meet your hatcheries needs. Slow enrichment, fast enrichment and HUFA levels in excess of 8% of dry weigh rotifer biomass easily obtainable.
