Shellfish Diet 1800® is a mix of four 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 (standard) and 1 gallon sizes (special orders).

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.

Microalgae Amount
Isochrysis 30%

Other Applications: Shellfish Diet 1800® is also an excellent feed for ascidians/tunicates, sea urchins, soft corals, brine shrimp, and copepods.

Shellfish Diet 1800® is part of the Instant Algae® product line and does not contain any preservative chemicals or filler material - just pure marine microalgae.
