General for marine microalgae:

Marine microalgae from Reed Mariculture Ltd. Consists of whole algae cells that are concentrated in pure saline. The cells are not damaged by drying or other procession that causes leakage of nutrients into the water. The algae from Reed are not artificially enriched, as some freshwater salmon products may be.

All marine fatty acids originate from marine microalgae. However, in freshwater algae there is no. In fish, they are normally found in the metabolised form triglycerin, and fish oil consists solely of fatty acids in triglycerin form. Most marine fish larvae are difficult to absorb fatty acids in triglycerin form. However, the algae contain the fatty acids in phospholipid form, and in this form the fatty acids are readily available to the fish larvae.

It has been found that the fatty acids EPA and especially DHA are essential for the development and survival of the fish larvae, and it has been my focus on giving lipids to lipids on this form. Algae, however, contain a lot of other substances in addition to the fatty acids, and since one is still far away from a complete picture of the larva’s needs, an enrichment of the prey with marine microalgae will provide a much wider dietary composition than processed products.

Instant Algae® Nannochloropsis

Nannochloropsis is a small green lizard that is widely used in aquaculture industry to cultivate less zooplankton as rotators and as “green water” to create the desired turbidity in the water. Nannochloropsis is also used in the saltwater aquarium market.

Instant Algae The Nanno 3600® has 3600 times the density of a common algae culture. Thus, 1 liter of Nanno 3600® will replace almost 4000 liters of culture with live algae.

The Nanno 3600® has a very high content of EPA, and the extremely elastic cell walls of the algae make it freezing for long-term storage.

Fish farming: Nanno 3600® is used mainly for cultivation of rotators and as “green water”.

Breeding of shellfish: Nanno 3600® works very well for mussels, but has traditionally not been used for oysters or scallops. However, studies at work show that Nannochloropsis may work as well or better than Isochrysis and Pavlova on larvae.

Storage: Instant Algae Nannochloropsis can be stored in a refrigerator for up to 3 months (preferably between -1 and + 3C). For longer storage time, Nanno can be frozen (up to 2 years).


Instant Algae® Rotifer Diet HD

Rotifer Diet ™ HD is a marine microalgaurus designed for the production of high-quality rotators and high-density cultures at a low cost. Rotifer Diet is a combination of microgenalgia Nannochloropsis and Tetraselmis. This combination gives an increase in rotator production of about 20% compared with the use of Nannochloropsis alone. Rotifer Diet is a 100% complete solution and no other additive is needed to produce high density rotator cultures.

Rotifer Diet was initially developed for high density rotifers, but has also proven to work very well for low-density cultures and in batch cultures.

For protocols and instructions on feeding and smoking rotator cultures, see information at


Instant Algae® Pavlova

Pavlova is a small brown algae that has a very high content of DHA. Along with the excellent ability of the algae to stay in suspension, this makes it very suitable for anrike rotators and other zooplankton. Pavlova is very difficult to grow so very few breeders can grow these themselves.

Pavlova has a nutrient profile that is close to Isochrysis, but has a more complicated sterol composition. This has contributed to the popularity of the algae for the enrichment of rotations among fishermen of marine fish.

Fish farming: Pavlova has a very high DHA and EPA profile and is therefore very suitable for growing zooplankton cultures.

Breeding of shellfish: Pavlova is very suitable for oysters, scallops, mussels and scallops.

Breeding of prawns: Pavlova is widely used for DHA enrichment.


Instant Algae® Isochrysis

Isochrysis is a golden / brown flaggelat that is widely used in aquaculture. It has a high content of DHA, but lacks EPA. This has meant that it alone or together with Pavlova is widely used to animate zooplankton such as rotations and artemia in relationships where one wishes to increase the DHA / EPA ratio. Isochrysis is the main ingredient in the diet used in shellfish and in some shrimp farming.

Fish farming; Used to DHA enrichment of rotators. It is also the right size to carry artemia and copepodes in general.

Breeding of shellfish: Isochrysis is the most common algae used for oysters, scallops, mussels and scallops.

Breeding of shrimp: Isochrysis used for DHA enrichment.


Instant Algae® Tetraselmis

Tetraselmis is a larger green flagellate with a very high lipid level. It also contains natural amino acids that stimulate skin intake in marine species. It has proven to be a very suitable for rekeyngel.

Fish farming: Tetraselmis used with Nannochloropsis for the production of rotators. (see Rofiter Diet HD) It is also suitable for the administration of artemia.

Breeding of shellfish: Tetraselmis is a common feed for oysters, scallops, mussels and scallops.

Breeding of shrimp: Tetraselmis is a very suitable for increasing the growth rate, as well as fighting the “zoea” syndrome.


Instant Algae® Shellfish Diet 1800®

The Shellfish Diet 1800® is a mix of four marine microalgae, all of which have proven to be very suitable for many shellfish, including oysters, scallops, mussels and scallops. A composite diet for shellfish shows a significantly better nutrition profile for all types of shellfish, increasing growth rates and decreasing mortality.

The Shellfish Diet can be used throughout the full-time up to full size and has proven to work as well as living algae, and is a complete product for shellfish.

The dry weight of Shellfish Diet is 9%. The number of cells varies slightly with the seasons, but usually ranges around 2 billion per ml. Shellfish Diet consists of:

Other uses include crowballs, raudade and brine
