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, 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.

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.
