Isochrysis is ideal for Fish, Shrimp, Oysters, Clams, Mussels, and Scallops

Isochrysis is a small golden-brown flagellate commonly used in the aquaculture industry. It is high in DHA and often used to enrich zooplankton such as rotifers or Brine Shrimp (artemia).

Isochrysis is:

1. Used for DHA enrichment of rotifers. It is also a good size for feeding brine shrimp and copepods.

2. The most commonly used algae in the aquarium for oysters, clams, mussels, and scallops

3. Used for DHA enrichment, (DHA Docosahexaenoic Acid)  an omega-3 long chain polyunsaturated fatty acid produced only in brown algae (Isochrysis). DHA is one of the building blocks of neural tissue. It is very important in the development and growth of larval fish, shrimp, and shellfish. Our Isochrysis phytoplankton is not a live product and can not be cultivated from.
