Instant Algae
  > Printable version

Instant Algae is your easy solution for replacing or supplementing live microalgae in commercial fish, shrimp, shellfish and ornamental hatcheries, universities and research.

Instant Algae is real marine microalgae, grown under laboratory conditions and concentrated for easy storage and long life.

Instant Algae is not live and cannot be used as starter cultures - it is an inexpensive bulk feed.



Different species:




Nannochloropsis is a small green algae that is extensively used in the aquaculture industry for growing small zooplankton such as rotifers and for Greenwater. It is also used in reef tanks for feeding corals and other filter feeders. Instant Algae Nanno 3600® is 3600 X as dense as cultured algae, so 1 liter replaces almost 4 metric tons of live algae! Nanno 3600 is available in 1 quart and 1 pint bottles, and 1 liter bags.

Fin Fish Hatcheries: Nannochloropsis is the single best food for growing rotifers. It has an very high EPA level and can be frozen for long term storage. It also works very well for Greenwater.

Shellfish Hatcheries: Works very well with mussels. It has not been traditionally used with oysters and clams, however a study currently being done at a university in Los Angeles indicates that it can work as well or better than Isochrysis and Pavlova with larvae and post set.

Storage: Instant Algae Nannochloropsis can be stored in a refrigerator for 3 months (best if stored at -1 to +3C) or it can be frozen for longer shelf life (2+ years). When frozen the algae will "hard-freeze" like ice.

Ice Cubes: If you have received a liter of Nanno and don't plan to use it all within 3 months we suggest making it into ice cubes. Simply pour the algae into a standard ice cube tray and freeze for 24 hours. Then take the cubes and store them in a plastic bag in your refrigerator. As you need more algae remove a cube from the plastic bag and thaw.



Pavlova is a small golden/brown flagellate that is very similar to Isochrysis. It has a VERY high DHA profile and is excellent for enriching rotifers and other zooplankton. Pavlova is very difficult to grow so it is not produced by many hatcheries.

Pavlova is similar in nutritional profile to Iso, however is has a more sophisticated sterol composition so it is very popular with cold water fish hatcheries (such as cod) for enriching rotifers.

Fin Fish Hatcheries: Pavlova has both a high DHA and EPA profile so its good for enriching zooplankton. We have received very good reports on larval survival from hatcheries that use it to enrich brine shrimp.

Shellfish Hatcheries: Pavlova works very well for oysters, clams, mussels, and scallops. It is also used to increase the DHA / EPA levels in broodstock.

Shrimp Hatcheries: Used for DHA enrichment




Isochrysis is a small golden/brown flagellate that is very commonly used in the aquaculture industry. It is high in DHA and often used to enrich zooplankton such as rotifers or Artemia. Isochrysis is a primary algae used in shellfish hatcheries and used in some shrimp hatcheries.

Fin Fish Hatcheries: Used for DHA enrichment of rotifers. It is also a good size for feeding brine shrimp and copepods.

Shellfish Hatcheries: Isochrysis is the most commonly used algae for oysters, clams, mussels, and scallops

Shrimp Hatcheries: Used for DHA enrichment



Tetraselmis is a large green flagellate with a very high lipid level. It also contains natural amino acids that stimulate feeding in marine animals. It is an excellent feed for larval shrimp.

Fin Fish Hatcheries: Used in conjunction with Nannochloropsis for producing rotifers. It is also a good size for feeding brine shrimp.

Shellfish Hatcheries: A standard feed for oysters, clams, mussels, and scallops

Shrimp Hatcheries: An excellent feed for increasing growth rates and fighting "zoea syndrome".

Thalassiosira weissflogii


Thalassiosira weissflogii is a large diatom (6-20µm x 8-15µm) that is used in the shrimp and shellfish larviculture industry. This algae is considered by several hatcheries to be the single best algae for larval shrimp. The large cell size (16 X the biomass of Chaetoceros and 3 X the biomass of Tetraselmis) extends the algae feeding period until the end of the PL stage.  During the winter this algae is about 15 microns, but shrinks to about 5 microns during the summer.

The color of TW varies from brown to green to yellow, depending on the amount of chlorophyll in the culture. This color change does not in any way affect the quality of the algae.

Fin Fish Hatcheries: Good for feeding copepods and brine shrimp.

Shellfish Hatcheries: Due to its large size TW is an very good feed for post-set (200 microns and larger) oysters, clams, mussels, and scallops and for broodstock conditioning

Shrimp Hatcheries: TW can be fed from mysis well into the PL phase. This is a real advantage because the high lipid and carbohydrate levels continue to boost survival and growth rates.


 Shellfish Diet 

Shellfish Diet 1800® is a mix of five marine microalgae that all have demonstrated success with a variety of shellfish including oysters, clams, mussels, and scallops. A mixed diet provides a much better nutritional profile for all types of shellfish, increasing both growth rates and survival. 

Shellfish Diet can be used with pre-set larvae all the way up through broodstock and will typically perform as well as live algae so it can be used as a complete live algae replacement.  1 quart of Shellfish Diet will replace the equivalent to 1800 liters of dense algae culture.  This product is available in 1 plastic bottles of 1 quart, 1 pint, 1/2 gallon and gallon sizes.

The dry weight of Shellfish Diet is always 9%.  The cell count varies depending on the time of the year but is roughly 2 billion cells per ml.

Rotifer Diet HD

Rotifer Diet HD is a marine microalgae feed product for producing high quality, high density, low cost rotifers.

Rotifer Diet HD is a combination of the microalgae species Nannochloropsis and Tetraselmis and results in a 20% increase in rotifer volume over pure Nannochloropsis.  It is a 100% complete feeding solution, needing no other feed additives to produce dense cultures.

Rotifer Diet HD was specifically designed for high density rotifer systems, but also works exceptionally well in low density and batch cultures.
